hybrid 100v vs H4350 vs H1000

[taliv]

I'm about to start loading 6 SLR, which is substantially similar to 243win I think as far as powder. Will probably use the new 105g berg or the 107SMK

does anyone have any experience comparing these 3 powders in terms of velocity, metering and accuracy and barrel life? the marketing is pretty confusing from hodgdon

I ran 4350 in my 6XC and had great experience with that. wondering if the 100v or 1000 are better.

thanks

H4350 is a great powder in the .308 based cartridges such as .243 .260 .7mm-08 ect. I use it in my .260 with excellent results. I was going to try H1000 but it would be a little to slow.

I've been working on a 100v load in .243 - have not yet replicated the accuracy that I was able to get with IMR 4831. This was in a hunting rifle, using 100gr bullets. However, the small granules of 100v meter very well.

Be really, really cautious with the H100V.
The lot# I have is substantially faster burning than the one Hodgdon worked up data with.

I blew primers in my .257Roberts with a 2gr below listed load (48.0gr w/100gr bullet); I was using 46.0gr. I had to drop charge to 44.0gr to get acceptable pressures and velocity was below that of H380 or H414 and they aren't loaded to +P levels.
The Hodgdon data is not even +P level for the "Roberts". They "suggest" 44,000psi for the 48.0gr load. Glad I didn't try it !!!

Back in fall of '11, I was at the range and a fellow was shooting a Remington VTR in .243. He was shooting some fabulous groups with some 105gr VLD's. He was shooting a BR target and getting near 1-hole groups. He was using H1000. He said it was the best powder he'd ever found for the .243.
I'd start there...

I agree H1000 is too slow a powder for that cartridge but H4831 is probably not.

You're asking about H4350 and H4831 has already been mentioned. Why not give HYBRID 100V a try since Hodgdon is reporting it falls between those 2 powders. Several friends have been using it in short magnum calibers and they tell me it's an extremely accurate powder that burns well and produces single digit SD numbers...

Sorry I can't give you first hand reports 100V but I trust the 2 guys who told me about it. Heck, it's worth buying a pound to try...

So far I have only worked up one load using Hybrid, and it was for a Sako Hunter in .243 using the 100gr Nosler Solid Base. Here is a pick of the target I used.


I cleaned the barrel at around 20 shots or so, and the bottom right sticker was my fouling spot. The bottom left are the two final loads with the two flyers shown caused by the barrel heating, and slightly rubbing the stock. I have since relieved some wood and the groups are basically one hole now.

This said I have had the best overall results using H-4350 with several .243's over the years. IT also works well in the Sako, but I simply wanted to try out the Hybrid powder and am not complaining with the results one bit.

i used an acculab scale and harrell culver benchrest measure to throw and weigh a bunch of charges and then compared the results.

(yeah, i know, the harrell is an overrated POS)

but the net seems to be changing to hybrid 100v won't give me good enough results to skip the weighing process and just throw.

(for comparison, i weigh my match loads to +/- .05 grains and just throwing would only put me > +/- .20 grains)

anybody have different results?

I had high hopes for the 100V in my 25-06. I'm in the same boat as Goose on my thoughts, I thinks it's faster than advertised. At least concerning my lot of powder, luckily I only had 1 lb. I have a thread from a month or so back discussing this and after going through the suggestions of things to look for, I narrowed it down to the powder. The load was also nearly 2 grains (1.7) under published max. Flattened primers and stiff extraction resulted. It was however accurate on the lower safe charges of 48.0 and under. I have since switched to 4350, it seems more stable during development. I keep the hybrid around for minimum loads and plinking, no velocity chasing with it.

Hi Folks,
First post here. I was searching the web for more information on the Hybrid 100V powder I tried today before I buy a quantity of it. I have had fits over the last few months trying to find a powder that would work well in both my 25-06 and my 300 Win Mags. I loaded 50 rounds at recommended max from my latest Hornady book and went to the range. I once again tried RL22 and IMR 4350 in the 300's and as usual I am all over the paper. I tried a few rounds with the 100V and have been astounded. The two rifles I was using are Remington 700's in 24 and 26 inch barrels. The 26 inch placed 3 rounds touching at 100 yards exactly where I want them and the 24 inch barrel would have done the same thing except I pulled on the second round and it placed just over an inch away. I've used IMR4350 in my 26-06 since the early 70's and regularly touch all three rounds at 100 yards. I'll have to try the 100V in the 25 to see if I can keep the same great results I've always had with 4350. I am a little concerned about temperature performance because my Son and I usually hunt from New Mexico to Montana from October to the end of November and sometimes it can be bitterly cold. We're here in Colorado and it of course gets cold here as well. Does anyone have any experience with performance variations with powders under very cold temperatures? I've never heard of performance degradation under low temperatures, living under a rock I suppose. I decided I was unhappy with my M77 last year when I missed a 360 bull which my son got with his shot. Using RL22 I cound'nt keep the Ruger on the 12 inch paper. I haven't chrono'd the load yet but the book says 3100fps which I will place at 3 1/4 inches high at 100 yards. This zeroes me at 300 yards and just over 4 inches low at 400. 200 yards is just over 2 inches high. I like the flat trajectory relatively speaking out to 400 yards. I use the Hornady 180 grain Boat Tail Spitzer Point #3072. CCI Magnum Large Rifle primers. Thanks for letting me talk your ears off.

M376X6,
Welcome to the forum.

It's my opinion you will have better results using 4831 in the 25-06 and 300 Win Mag. 4831 a slightly slower powder than 4350 and will probably improve accuracy in the 300 Win Mag over 4350 but of course every rifle is different and you can't know until you try it. As for worrying about cold temps, I suggest using H4831 or H4831SC since those are part of Hodgdon's Extreme Powder line which are supposed to give you consistent performance even in extreme heat and cold. (and they do)

Hope this helps you a little...

H1000 has been one of my powders for a good while, like 20 or so years for the .270 win, .243 win., and 30-06 with great reaults. I also have used a lot of IMR-4350 and RL19 as well for those cartrodge applications.

For the heavier 105 gr. bullet in .243 win. loads, the slower burning powders have always been my go to powders. So my first choice would be either IMR-4350, then RL19, and then H4350. But all 3 work very well and produce very similar performance, in both velocity and accuracy. And don't over look H4831 SC either. It's a fantastic powder for that .243 win.. The problem with determining the best of those that have been discussed on this topic, is that there are a good number of great performing powders for that cartridge.

Thanks Guys,
Called and spoke with the folks at Hodgdon's this morning. I described the typical hunting scenario we are involved with and they stated that 100V is not as temperature sensitive as IMR4350 (my powder choice for 40 years) but not as good as the extreme powders. They listened and said I shouldn't have any problems whatsoever. The problem would come with higher SD's at higher temps than the average we hunt in. I have tried 4831, in fact, I have a fairly full bottle of it sitting on my powder shelf right now. While better in my Ruger 300 Win Mag than RL22 (which was horrible) it wasn't as good as the IMR4350. The rifle I had the worst problem with was my Ruger M77. The Remington 700 CDL 26" barrel and the Remington 700 LS 24" barrel did fairly good with RL77 but they loved the 100V. Based on what Hodgdon said this morning I am definitely going to keep giong with the 100V and before I head to Wyoming in a week and a half for deer I'll load up some in the 25-06. But I may just keep the IMR4350 for the 25 and go with 100V for the Win Mags. It really won't bother me to have two powders, it's just some silly notion to have only one powder for such different type of rifle calibers. Thanks for your input, it is always super nice to hear from folks who have good knowledge and experience.
