Got my hunting load for this year. 95 gr.777ff with a 777 primer. 300 gr.speer gold dot in a harvester crush rib sabot. Shooting out of an Omega. I tried regular win. 209 primers and got bad crud ring. Remington kleenbore i got less crud ring but a lot of blowback. Crud ring is about the same with the 777 primers as with the remingtons but no blowback. Getting good accuracy with this load.
