Hello all, recently reloaded for 7mm-08 160 grain Speer Grand slams. I loaded them spec with h4350 44 gr total federal mag primer. I had an SD of 17.6 and wide velocity spreads. My SD is usually below 10 even with my muzzleloader. I triple check my powder before putting it in the cartridge. Is there something I am missing? I loaded these for a friend but eventually want todo a full work up on these for myself.
I am not looking for the ultra pinpoint accuracy. These are in the woods general bear and deer loads. I would like consistency though.
A low SD is understandably desirable. However, if, like you mentioned with not needing absolute accuracy, if this is a Woods gun for deer and Bear then having a high SD really isn’t going to hinder you.
But if you do want to chase it that is certainly understandable. I would think the biggest things to improve would be changing your primer, a 7mm-08 doesn’t typically need a magnum. Or you may change powder
You may be very right on the magnum primers. Reason I prefer magnum primers is the conditions I hunt in. -27 was my coldest night in a tent last year while hunting.
