So I'm just beginning to get the hang of handloading, but i'm having a hard time finding .311 diam bullets for my Parker & Hale Sporterized 303. I can't seem to find them in Bass Pro or any local gun stores, so i started loading .308 bullets into my brass. They give mediocre accuracy with IMR 4895 an even worse with 4320. Right now i have 20 or so loads with Sierra Varminter 110gr hollow points. They push 3000-3100 fps with 40.0 gr of 4895. Any tips or tricks to help me improve my accuracy? (Without the obvious of using actual .311's please? )
Cheers,
Cody.
