I worked up a load in my GP100 6" using Zero 158 gr JHP bullets and Bullseye powder, CCI 500 primers and mixed brass. I started loading at 5.8 in 10th grain increments till I got to 6.4. No signs of primer deformation, no split cases, but I am getting some flame between the cylinder and the barrel and of course out of the barrel. The recoil is pretty stiff and I don't think I will go any higher for plinking loads. It does shoot 2" baloons at 65' very consistantly. My main worries are damaging the pistol or wearing it out prematurely. Is this a valid concern?

I think I will look for a better powder for higher midrange 357 loads and relegate the Bullseye for the 38 and 9mm. Any reccomendations for 357 powder?
Thanks in advance.

I have developed a good upper, mid range load for 158 JHP's using H110.

There are a lot of good powders available that will do the job. I like SR-4756 for both .38 Special and .357 Magnum, but not for full power loads in the Magnum. For that, I use H-110, Winchester 296, or for really heavy bullets, Hodgdon's Lil'Gun.

Hope this helps.

Bullseye is a very poor choice of powder for trying to get Magnum level performance.

It is at it's best with low velocity, light target loads.

When you push it to the limit like you are almost doing, even the slightest variation (like mixed brass) can push you over the edge real easily.

If you want light target loads, Bullseye is your powder.
If you want Magnum power, use a slower powder like Unique, 2400, H110, WW296, Lil'Gun, etc.

AA#5 is a good powder to span the 357 reloading range. I consider it a "jack of all trades, master of none" type of powder: it doesn't do what 231 or Bullseye will do on the low end, nor what 296 does on the top end, but it generally works well with various bullet weights.

For the .357 mag I usually use Unique for 158gr cast. Blue dot for 125gr JHP's; 2400, AA#9 or H110/W296 for 158gr and heavier jacketed.

Most of the time I shoot .38's out of my .357's using swagged Speer or Hornady bullets and W231.

I think I will go with 2400 as I have seen it locally and know I can get it. As for the flame shooting out between the barrel and cylinder, is this a problem?
I plan on casting for 38, 357, and 9mm very soon. Is there a good all around powder that will work with all three? I don't mind getting a powder for each if I have to, but it would be nice to buy a big jug of one and be done for a while.

AA#5 or WSL and Unique would be my choice for the calibers you listed, I'm sure there are other good choices, but for .357 mag a slower powder will give you more joy :)

RC has the right idea. H110 and 2400 are what I use for magnum loads for my 357, H110 if I really want to see some muzzle flash! If I plink, I use bullseye.

Bear in mind that if, you may be over max levels already even if you don't see any physical signs such as primer deformation, ect, ect, so on, and so forth. Check the books, Mate and double and triple check with cross reference. If they say your okay, then cool. But always remember to use maximum powder charge with extreme caution. Keep a sharp eye.

W296/H110, 2400, Lil'Gun, AA#9, Blue Dot and 4227 are considered good powders for loading the .357 Magnum to full potential. If you want lighter loads HS-6, Longshot, Power Pistol, AA#7, AA#5 and Herco will also do a good job.

I use mostly W296 and Lil'Gun for my Magnum rounds and when I want something a little lighter I use Longshot when using Jacketed bullets.

If you're looking to use only 1 powder for the .38 Special, 9mm and .357 Magnum I would choose HS-6 for Cast bullets. The problem with using only 1 powder for Magnum and non-Magnum rounds is powder speed. The Magnum round should really use a slower powder than both the .38 Special and 9mm.

IMO W231 would work very will in the 9mm and .38 Special using a Cast bullet and 2400 for your Magnum rounds when using a Cast bullet if you buy 2 powders instead of only one.

Bullseye is a great powder for mid-range .357 loads. It's not as fast-burning as people think, and it has a very high energy content. (but I would use cast bullets for mid-range loads and save the JHP's for hot loads (BlueDot, 2400, or 296.)

You still have some headroom at 6.4 grains of Bullseye, quit worrying if you like that load.

I agree, Bullseye is a impressive powder, I have developed a few great loads for my shorter barreled handguns that slower powders could not compete with.
I must add that the recoil from hot bullseye loads are SHARP and can feel less pleasant than other powders.

My general purpose load is 6.7 gr Unique under a 158 LSWC with a Win small pistol primer in mixed brass. About 1150 fps.
I like Bullseye for 125's.
I get some great velocities with AA#7 for hot 158's, but it take a LOT of powder, 10.7 grains in my gun.

These guys are right, Bullseye is for target rounds, not magnum.

I prefer W231 for target rounds. I use 5g under a 160g cast bullet in a magnum case for an outstanding equivalent of a 38spl. +P.

Midrange rounds can be achieved with BE or W231, but many prefer a medium powder like Unique, and for good reason.

My magnum go-to powder is W296/H110. 2400 has given me great results in the .357 too.

Thanks guys, I'll get some 2400 for the 357 and When I finish up the bullseye i have on hand I'll grab a can of W231 and Unique and see how that works.
Thanks for everything.

I think this is a wise choice, since you're clearly interested in working up the power in your .357 loads. In this caliber, you can't go wrong with 2400.

2400 will make some flames too. I know my std 14 grain load out of my blackhawk makes a pretty good flash. It packs a pretty good punch in a rifle too.

I'll throw my 2cents in. Afterall, I've been handloading for almost 3mos now.:what: I've also been loading my way up with different bullets/powders for the 357mag. And, I've found what not to use. Red Dot under a 158gr LSWC. Poor choice. Unique worked well for me with that bullet, and so did Clays. Someone mentioned W231, yesterday 8.1gr of that powder was most accurate out of 6 different powders I was experimenting with under a 110gr Hornady XTP bullet. I don't have a chrono, but the report it gave indicated it was neither mild nor wild..just right.
I'm glad I got into this hobby, it's a lot of fun.

My favorite load right now is 10.0 grains of Blue Dot, Nosler 158 grain JHP and Winchester small pistol primer. I'm getting 1140-1190 fps over the chrono, pretty consistent and accurate. Blue Dot is giving 90% of the velocity of 296, with 6.5 grains less powder and a standard primer, I like it. Plus, Blue Dot is clean.

Good advice here. IMO

Personally I would Shelf the Bullseye for Magnum top end performance.

Get some H110 or 296 (same powder) and work up a Load slowly. This powder will Ruin you though....It's Awesome,it has basically one use...."Pedal to the Metal or Nothing"

I like a 125gr Jacketed Bullet with 21.5gr of H110 and a Magnum primer.....<----This will Rattle your Teeth. This Load in My 4" GP100 chronos at 1545fps avg.

Get some!

If I recall, you stay within 3% of the charge weight with the H110, is that correct? What I am looking for in the 357 load is something around 3/4 of the total available power. Maybe between the level of Rem bulk and a +P loading. Then will work on the accuracy. I think I will get some 2400 & blue dot for the 357 and leave the bullseye,w231, and unique for the 38 & 9mm.

Bullseye will get you your 3/4 loads (it's an amazing powder) but that's pushing it. Herco is perhaps a better choice because you'll be right in its optimal range.

You don't really want a powder you can load down to low power levels. They burn very inefficiently that way. You want a powder than maxes out at just over the power level you are trying to achieve, so you are working on the upper end of the curve.

my .357 load

14g 2400 158g SJRP "Magtech"
win cases wspm primer

plinker load / 38+p
5.5g Unique 158g RN Rainier lead safe WSP
or
5g Unique 158g lead RN WSP

Both loads are very versital in a 6-gun or lever gun.

I only load RN's so i have no feeding issues w/ the lever actions

Sorry, I didn't make that clear enough. I will not be using Bullseye in 357 anymore, I will get some 2400 and use that. The Bullseye will be for the 38 and 9mm. I was also just clarifying for myself that when using H110 you don't vary the charge weight by more than 3%, right?
