30 BR powder

I was kind of figuring I'd have to be at a higher charge with the slower ball powders. Wasn’t expecting your setting to drop almost 5gr more. Bulk density showing up.
Of course, I'd work my way up towards there because every powder just reacts differently, even though it might be right next to the one you're currently using.

On a whim, I tried CFE 223 in the 6-BR/105 and it worked great. What I didn't expect was how well it worked with the 112s.
I went back and bought the other 8lb-er because momma didn't raise no dummy. It's right next to VarGet on the chart, so I was comfortable experimenting with it.

I think the cfe223 will be too slow for the 30-BR, so I'll concentrate on the faster stuff.

Thanks for the info on the SW/Lovex powders. I'll see if I can find some to play with.

I saw n120 mentioned a few posts up. FWIW, it is about 2 full grains faster than h4198...for a starting point of reference. The burn rate charts can be misleading at times. N120 is a good example of that. Very good powder though. The old stuff was magic pixie dust. The new is still ok too but the old spoiled me.

"Slow" is not, of necessity, "bad". One good example of bulk-density : burn-rate, via 30 BR, is comparing H-4198(Extreme, or, ADI AR2207) to H-322 (Extreme, or, ADI AR2219 ): at the volume setting which drops 34.8 Gr. of H-4198, my Jones measure drops 37.2 Gr. of the H-322. Both of these powders and charge weights have won BR tournaments for me. The 2.4 Gr. heavier H-322 charge produces 100 FPS less MV . . . but, I never got a trophy for either velocity, or, BC. Just be prepaired to throw the chronagarph in a dark closet . . . or, maybe not!

Al Nyhus and I have discussed the powder thing ad nauseam - as he pointed out, many of the "newer" ball powders, up to and including CFE223, when replacing H-4198, in a measure, set to drop 34.8 Gr., will drop >39.5 Gr. of the ball powders. Especially if precision is THE measure, based upon experience, some, if not all, may prove useful, requiring only some common sense and judicial working up, thus assuring no excessive pressure surprises.

That said, I have obtained tournament winning precision ( yes, won registered NBRSA/IBS tournaments) using H-4198(Extreme); H-322(Extreme); RL7; Win 680; Tu2000; N-120; H-4227. over the past 15 years or, so, I have acquired numerous powders which were purchased to "check it out", which are yet to be tested - they were all opened and the bulk densities compared to H-4198, then set aside . . . just not enough time.

I keep wondering - especially, with the powder shortage, "who is doing THE testing" . . ?? What is everyone afraid of - potential success?? Once upon a time, we were experimenters. ;) RG

P.S. Some of these powders can and WILL generate EXCESSIVE pressure - if doing experimental load work-ups, one must be cautious and pay attention . o_O

Randy,
Out of necessity in my neck of the woods there has been a forced migration to LT30 and N130 for the 30BR. No one seems to be complaining. I've tried N120 but not so much as to have drawn a conclusion. Gonna give it another try when the season slows down a bit. Good post. Thanks --Greg
 
So if a powder like N120 or H322 is a good replacement for H4198 in the 30 BR, does that mean they will also work well in something like the small 20 caliber cases?

I have not, but it is a Ball powder, meters extremely well, was specifically made for the .30-06, very temperature insensiitive. 32 lbs? I'd be loading some and see how it works.

760 is way slow. Not saying it won't shoot small because I don't know...never tried it, so it might. I just think there are several available options that are more appropriate. I'd like to see some tiny groups but along with speeds posted. It's not a race so it might get things moving along but these small cases tend to like pressure and there's no down side to powders that shoot equally well with lower muzzle pressures at the same time, so I lean toward faster for application powders unless something just knocks my socks off. These little 30's are amazing though and almost nothing surprises me when it shoots small in one.

Win 760 in .30 BR?! Lord have mercy... no! As @gunsandgunsmithing mentions, it's much too slow.

100% case fill, using Lapua brass and Bart's 112gr X-OUT, with a COAL of 2.270, equates to 36.2 gr. of Win 760. That load would produce on the order of 25K psi and a velocity of 2200 and change fps.

If anyone ever places in a match using Win 760, I'll eat my sock!

Yeah, now I've seen his other mentioned powder, h322 shoot very well from a 30BR but I've just never tried something as far out of its wellhouse as 760 is. Density is a huge thing and since I haven't tried it, I didn't want to say "hell no but I settled for just no, instead. Lol! There are powders that due to density, might surprise you and me both in a 30BR. But h322 is about as slow as I'd go...or Benchmark, etc. Those have similar density though and there may well be a ball or similar that you can get enough in the case to make up for how slow it is...and since I haven't tried it, I won't go that far and say it won't work either. Just that it seems too far off to make much sense to me...unless we run out of better alternatives is all. The LT32 is too slow too but it has good density and is in the same area code as h4198...not zip code. I've seen lt32 shoot great too, fwiw. Just very full and a bit low velocities with it at absolute max fitting in the case.

The powder situation is slowly getting better and there are better options is all I'm saying. If it comes down to 760 or a slingshot, I'll try 760. Lol! But do try the h322 if you can't find lt30, h4198, n120 or n130...and I'm forgetting some others. RL7 is good..very good.
 
N-130, H-322, Lt 30 and RL -7 all will shoot. Just tested them over the last week.
Went to a match today and a fellow shooter was selling off his powder hanging up his rifle. Illness. I pickup 5 pounds of H-4198. Hope to test some this week. Will be the first for me.

I was going to say Hoarder but you don't have quite enough showing. Yet.

Roger. I don't consider what I do hoarding. It's more of having brains enough to buy it when it was available years ago instead of not planning for the future. Every time a Democrat became president we always had shortages of some sort. This was my plan to avoid that. I have 50 pounds more of N130 than I do this stuff and I have a little more N133 than 130. Same with brass, bullets and primers. I always planned way ahead. But now it's on hold since I stopped competing. Someday I will return. I had to laugh Roger when LT30 went from $343.00 to $465.00. Totally ridiculous.
