.243Win 55HH How Fast?

WARNING: Varget and IMR 4064 eats barrels with these loads up to 80g Sierra blitz bT. AA4064 burns a lot cooler, just as accurate.

Calvin, 257 Weatherby, 80-85g at 4130 is real world with R#19, try cci 250 and fed 215 primers.

Wow. That seems insane but I believe you haha.

I'm loving my weatherby so far. All I've tried is 100 grains. 3720 with imr 7828 and fed 215s. Can't complain!

But yeah, one day when I run out of existing supplies I'll try the 75 hammer and hope to hit 4200-4400.
