Your choice for .243 powder

I'm running 95gr SMK's and looking for a good powder for a reasonable price. I've tried RL-17, seemed to be a decent powder, I've tried H4350 and had good results with it as well. I've bought a new LNL powder dispenser so it will need to flow well with that dispenser. The H4350 bridges a lot so I don't think that is a choice that I would want to buy 8lbs of. I didn't own the LNL when I tried the RL-17 so I can't comment on its dispensing.

Try IMR7828 SC for your 95's and H4831 SC for 87 to 65 grain bullets. I posted a pic of 100 grn. Sierra Gameking with 45.5 grns of 7828 SC in the rifles section the thread title is "cheap accuracy" good luck

Shooter,

If I were starting on a new .243 today the first thing I'd buy as a component would be the Hornady Interbond bullet, one hundred gr for hunting and maybe something in the 75gr for very long range varmint. Although I'd have
a.22-250 for varmint.

With powder I'd start with H-Varget, simply because I shoot it in so many different rifles. If H-Varget didn't make me happy then I'd pull out H-4350 and give it a try. I've had so much experience with both powders in a .234 I just can't imagene trouble with either of those powders.

Primers would have to be the CCI BR2. It may cost a little more than other primers bur after many test it is the only primer I'll use in standard cartridges.

Well that's my opinion, it and a dollar bill might get you a cup of coffee. Let
us know how it works out for you

I have been running reloder 22 out of a rcbs chargemaster and a regular old rcbs thrower. It is not the best metering, but if I take my time and trickle it works fine.

That powder has given me very good accuracy and has dropped quite a few deer. Shoots sub minute groups pretty easily. Not sure on the exact velocity off the top of my head. Around 2900 I think. Could be wrong though.

redbullitt was that a Uniflow dispenser?

BigBob, my twist isn't fast enough for anything heavier the 95gr. I gave the 105 Amax a shot, just too heavy.

I have had good luck with IMR 7828 in a 243 win also... 95 gr Nosler BT.

Varget and IMR-4064 cover all of my 243 loadings. I have been thinking about trying some of this RE-17 that performs so well in my 30-06.

You'll find that Win760/H414 gives great performance and flows through a measure like water. I suggest using magnum primers with the ball powders.
Rel-17 works very well in the 243 Win, but no idea if your measure will handle it well.

There are some new powders on the scene that show great promise, but I have no experience with them.
Check out www.hodgdon.com and www.alliantpowder.com and compare.

Well hell, I'll have to give the Varget a try seeing how I have 4lbs of the stuff I bought for the 308 but haven't tried. Mag primers for the 760/414? Is it really that hard to light off?

I'll load up 15 rounds for this weekend and see how it does.

It was nice to read this thread. I've had real good luck with H4350. I have several test loads put together with Supreme 780 and Hybrid 100V but I haven't been able to shoot them yet. I hadn't even thought about trying the RL 17 and RL 22 even though I have a couple cans of each. Those are all for the 95 and 100 gr bullets. I need to find some load data for the 75 gr bullets I got in now. And I need to figure out a good load for the Ramshot powders I have.

Nice thing about the .243 is it doesn't seem too picky. Just about any powder I have used gets pretty decent results and it makes me feel like a real expert. :)

Gotta agree with that statement, funshooter, the 243 is easy to shoot easy, it's hard to find a combo that doesn't work! Maybe a new thread call what won't work in your 243 would be better.

I have huge temp swings here in Vegas. So keep that in mind. I've been told the RL-17 was designed to be a close match to Varget. I've used the 4064 in 308 here but rounds that run well in the winter, over pressure in the summer.

Thanks for the suggestions.

R-15 and varget are almost twins I believe. I run varget and hybrid 100. varget behind a 75gr varminter, and hybrid 100 behind a 85gr tsx and they both shoot 1/2 moa at identical POI at 300. But like has been said what doesn't work in the best cartridge ever invented:D varget will be very forgiving as will r-15

I've had great luck with IMR 4895 for bullets in the 85-100gr range. Better results than with H4831sc so far.

Ramshot Hunter is a spherical (ball) that meters very well, is temperature insensitive and burn rate is about like R-19. Nearly ideal for .243!;)

Sin City Shooter,

I :)have had great results using H-4350 and H-Varget. I think either one will give you what you're looking for.

I just wanted to bump this thread to thank Funshooter45. I tried both the Supreme 780 and the Hybrid 100v. Both meter extremely well (slight edge to the 780) and both seemed to shoot very similar to the H4350. I read that the Hybrid 100v is basically H4350 but has been cut even shorter and has rounded ends. I tested all 3 powders this weekend with 95gr SMK. The wind was blowing a good 20 mph+. I thought all 3 performed great considering how hard it was blowing. I just ordered 8lb of the Hybrid 100v, but would have no problems with having the Supreme 780 on my shelf either. I've seen some posts regarding the need for mag primers to light the 780 off. Is that really necessary? I had no problems with standard LRP.

I have been running 41.5gn of IMR-4350 behind 95gn Berger vld-h, with great results. RL-17 seems to be the short cut and temp insensitive version of imr-4350, i bought a pound to try.

Will post results when my 5 week old son lets me go to the range. :)

Yeah, I liked the RL-17 too. I was looking for something that didn't bridge in my LnL powder thrower. I had ran out of the RL-17 before the new dispenser arrived. I think the guys here are right, it would probably be easier to say what doesn't work in the 243.

I run 38 grs of IMR 4064 behind a Sierra 85 gr HPBT for varmints and 40 grs IMR 4350 behind a Sierra 100 gr SP for when I use this for deer hunting.

Congrats.


I tried some IMR 4064 under a 65gr V-Max & wow it was great. i most be doing something wrong with Varget because it is by far the worst powder in all but one of my rifles & even in that one it's no better then anything else.

I guess the Varget is better then the WC 872.

varget works the best at the top end, and I normally use fairly heavy bullets...85 and up.. try a top end load, it is the most accurate in .243, 308, and 223 for me.. varget likes to be hotter.. not max or over just upper end

I can't get anymore in the case in the .223Rem. The 30-06 seemed to tolerate it the best but nothing tighter then 1.25" with the bullets I tried it with.

For my 243Win I am using the 65 V-Max & haven't tried any other projectile so far & I'm not sure there is any reason to.

I think I discovered a new favorite last night. I used some Ramshot Hunter for the first time last night. It gave me the best groups I have ever shot with that rifle. I was using some blems or seconds, I guess they were probably Hornady BTSP 100 gr. The bullets were amazingly close in weight I noticed, no more than 0.2 gr away from the 100 gr range. The best group was with 41.0 gr, not close to the max at all. But the 40.0 and 42.0 were also really nice groups. I am going to zero in on that range with finer increments. And I'm going to try the same powder for my 95 gr SST bullets too.

there are about five of us in my "social shooting circle" of friends.. we have excellent accuracy with 26.0 gr of varget behind a 55gr pill.. I run 24.5 behind a 75gr hornady bthp, with excellent results

Hi all, In my rem700 I use IMR 4831, for 100 gr Sierra Game king and 87gr Hornady both will hold under a inch at 100. The 100gr at 2930 and the 87 at 3230. The 100gr GK when put in the right place is good Whitetail medicine. My son got his first buck this year, shot was a little high but he dropped right there.

I'm starting to get worried about my rifle. Every one here says just about anything will work in a 243. My son has a Browning Stainless Hunter in 243. I have gone through the chart from min to max at .3 grn increments with 7828 and 4064 and am working my up with Varget now using Hornady 100 grn BTSP and 75 grn VMax. I will say the Varget has given the best results. I have gotten a couple of 5 shot MOA groups (with 32.5 grns if I remember correctly). I hope we can do better than that in that he traded a 1/4 MOA Stainless Stalker in 270 for this rifle.

Dakota Bones
April 3, 2011, 12:07 AM
My son's Rem doesn't like 4350 it shoots all over the place, but most people love it in a 243, MY 308 doesn't like rem cor-locks shoots 2" and sometimes bigger groups. But with Sierra,Hornady, or Nosler she will shoot under a inch if I do my part. Or try different bullet, don't think it is the Gun, some guns are just more picky then others.But not all off the shelf guns will be a tack driver, 1/4 MOA is a lot to ask for .

LOLBELL
April 3, 2011, 12:27 AM
I know I may be asking a little much, but until the last loads of today about 1.75 MOA is the best I"ve got. with the worst being about 2.75 MOA with the 7828 I think. I know it's not the norm but my SS Browning in 270 will tear one ragged hole with Varget and 140 grn SPBT Serria's. That has spoiled me. And like I said Logan's would shoot 1/4 MOA with Hornady 140grn BTSP and 7828. Maybe I have come to expect too much from Browning, but they have served me well for 25 years. I've got a 270 Bar that shoots MOA with factory stuff. I expect a little more from a bolt gun. :rolleyes:

Dakota Bones
April 3, 2011, 12:51 AM
Thats funny I too have a 270 BAR that will shoot MOA with factory stuff, don't give up try different stuff. You will find what it likes, that is why we handload to get the best out of the gun.

suzukisam
April 3, 2011, 06:42 PM
Varget now using Hornady 100 grn BTSP and 75 grn VMax. I will say the Varget has given the best results.

What is your twist? 100's may not work.. are you noticing any difference in groups between the 75s and 100's? also has anyone other than you shot the gun? I know this sounds insulting and I don't mean that, but I have had a few rifles that just about anybody but me could shoot moa or less with, and I could put one of those guns down pick my 243 and shoot ragged holes.. I have a weatherby mkV that I can't get under about 1.5-2 moa at 100yds my bro can shoot 3/4 all day with my handloads... me and the gun just don't like each other I guess...

sldo you may try running some jb down the barrel.. I have seen that clean up groups.. a 243 should not be that hard to get to shoot, especially a fairly new rifle.. check your crown..

April 3, 2011, 10:29 PM
1 in 10 twist and yes they do tighten up a little with the 75 grn VMax. I have some 95 and 87 gr bullets ordered. I want something at least that heavy in that he will be using it for Alabama whitetails along with all sorts of varmits. There has been 3 trigger pullers all getting the same results. Me being Dad I thought I could out shoot him But not so. He's got younger eyes and a steadier hand than I.

Long 100gr boat tail 6MM bullets can be a problem in a 1in10" twist, especially if you are not hotrodding them. You'll often find that the shorter, flat based 100gr bullets will stabilize in that twist.
Most often, any bullet weight under 90gr will be fine in that twist, be it boat tail or flat base.
IMR4064 and it's near twin Varget should be better with the lighter bullets.
Have faith in the Brownings.

Why does it have to be that heavy? I there a law in AL that requires a certain weight projectile? Are you concerned the bullet wont retain enough mass & weight to travel deep enough?

I suggest using the bullet the gun can reliably shoot. If there is a law dictating weight then maybe switch guns. If your looking at retention then buy a bullet that is built to hold together at the speed you want to push it or push the bullet at a speed it will stay together.

The faster you push the bullet the more it becomes frangible.

If none of this helps you maybe it will help the next guy reading it.

well that is good at least you know it is the rifle.. I have had really good results with the 75gr sierra varminters and the 85gr tsx.. try I run varget.. and hybrid 100... try some sierra.. your gun may like 'em
