6.5 PRC loading with 140 ELD

Unfortunately my testing (and a cursory google search) shows that Vihtavuori’s claims that N560 is temp stable is a flat out LIE.

I am running it in my 6.5 PRC with 143 BondStrikes getting outstanding SD numbers at 3000 fps now.

I have had great results with H4831sc but not great SDs and it seems to become unicorn turds as of late. I was getting 2934 fps with 140 eldx with a 24” barrel.

56.5gr H1000 at 2850 with a 140eldm shoots pretty well in my 20in barrel. Jumping them 45k. That same load was shooting well mid 3000s at 26in length b4 I chopped it for a supressor. Lost around 35fps per inch. I would not build a prc shorter than 20in unless it was a special purpose rifle.

You jumping those 40-50k?

Just put a 21" 7.75 tw on a defiance classic, bedded to a manners pro hunter. First custom for my chiropractor friend. I need to put something together for barrel break in. I have 100x pcs Peterson brass and 140eldm. If they shoot well, I'll keep loading them for him.
