I see some of you do not use mag primers when loading 296 and H 110. for 454 Casull loads.Is this because it is a rifle primer?I know with pistol primers I always use a mag primer with 296/110.Just dont wont any squibs.
I've had good results with Remington 7 1/2, CCI 400 and Federal 200 primers in .454 Casull. All give great accuracy, low extreme spreads and good velocity. My favorite is Rem 7 1/2. CCI 450 magnum small rifle primers have not improved any aspect of my .454 loads.
When I had a 454, I used 30+ grains of 296 and a cci small rifle primer. I never had any issues of squib loads. I'll admit, I didn't really do any cold weather hunting; coldest temperatures I had it out in and shot was 15-20 degrees F.
