28 nosler

[Orange Dust]

compared to the N570 thats what I found. I know its not considered a "dirty" powder compared to many others, and maybe I was using too much powder, i dont know. But pulling a patch after each shot I noticed its a lot blacker than pulling a patch after every shot of N570.

All powders react differently to some degree when the relationship between bore /capacity / projectile wt. changes. Some more than others. That's why there is a wide difference in opinion on powders. H1000 is great in some cartridges, and not so great in others, and that can change with bullet weight. Same with all the others. R33 is supposed to be the bomb with a 28 Nosler, but it isn't with a bullet lighter than 180grs. This kind of stuff is what makes this hobby so interesting. You never stop learning, scratching your head, and experimenting.

Those of us, that used the good ole 7STW (28Nosler ballistic twin), way back when, before the excellent powders of the early 2000's to present, found that the 7mm bore, mid-weight bullets and "slow" powders of the day, 20 shots was a max before the rifle turned into a long range shotgun. And cleaning was mandatory.

H4831, H1000(pre Extreme) and H5010 (pre H50BMG) were and still are excellent propellants. Now we've available new slower powders with better technology behind them.

FWIW, in 7STW, best combination of velocity and accuracy has been RL26 and 7828 with 160accubonds. I think you are leaving lots of velocity on the table if you're only running 162s at 3100. I do find RL26 dirtier than 7828.

Plus the barrel runs cooler with n570 than the others

yes I noticed that too, after 10 rounds I can still touch the barrel

I'm using R26 behind 160gr Accubonds. Running 3230fps in Nosler cases with no issues. Mine is 25" 1-9. Groups are just under .5".

I got a can of 8133 I'm hoping to try in my 7mm STW if I can find primers.

imm getting 3286 with rl-26 with the 162 gr eldx, no issues with brass or pressure

What is FWIW?

FWIW = for what's it worth.

I know, some of these abbreviations, google is your friend

You are firing 10 round strings in your 28 Nos? Expect 400-500 rounds of barrel life.

For what its worth, you answer was not overly informative!
