Sounds like a good time!
I did try a little 26 in it and I thought it worked pretty well... ...It's very dense so the case will hold a lot! You could likely run them between 3200 and 3300.
I'll keep an eye out for some N570 locally. I don't generally see it up here, and we can't order it from out of State. Maybe my brother can get some from his distributor. Thanks.I really think you should give n570 a try. I shot up to 86grs with the 225's and settled on 83gr for 3050' and great accuracy. There was still capacity left at 86gr so I know it's likely to work with a 197.
The si must be way different than mine. I maxed out around 81.5 n570 with fireformed brass. In my 24.5"bbl im estimated at 2950fps out to 800yds. With unfired brass i made it up to 83.5 i think and it shot great there. I had to drop 2 grains to maintain.
As a side note im really not a fan of this hornady brass. After 1 shot i can push the primers in by putting them on a table and pushing the brass down. This tells me its a warm load but even the unfired brass goes in almost as easy and the primers are still round as new and no ejector marks or anything.
Yours I'd a straight 30/375, right?I hear ya! I think it got worse the last batch I bought.
