I was wondering what everyone's experience with 75 or 85gr bullets using IMR4064 has been for accurate loads
I need a good load with the Sierra 80 gr. Blitz with IMR 4350 in an .243 AI. We talked on the phone before I purchased the rifle.I shot custom 6 Rems for coyotes. The 80g Sierra Blitz BT is hard to beat on knocking the life out of them before they hit the ground. My load was 42.0g of IMR 4064 with a Fed 210 and the bullets like to touch the lands at 3500 fps.
We killed hundreds of coyotes in Mexico with the 60g Sierra with 50.0g of Win 760 with a Fed 210, sub 1/4" accuracy at 4000 fps, and easier on barrels than the 4064 load above.
I have seen 85g Sierra BTHP and Spt zip through coyotes with them not even feeling it, seldom happens, but when it does it will stop you in your tracks on bolting another round in the gun.
All the bullets made on J4 jackets work very well on coyotes from 60-80g Bergers that I tried. The 62g bullets with 50g of Win 760 is beyond awesome in the 6mm Rem.
If you want to stomp on the gas, a max load of R#19, win primer with the 80g Sierra Blitz BT will get you some accuracy at 3600 fps, bump the shoulder each firing with a Forster Neck sizer and you will avoid FL sizing.
Good luck
