So I've been loading for the 12 twist for awhile and helping my brother with his Valk loads too, but this new project is something I'd like some input on. Primary purpose will be varmints and plinking, secondary will be deer, but not hunted hard, to stay legal for deer in this state, we need 900 ft lbs at 100 yds, with a 16" barrel, I'll have to be choosy on powder/pill combos, for now (based on the calculations I've run) running something in the 65-70 gr HARD and it should be ok. Obviously, I'll chronograph prospective loads.
With all this in mind, I'm thinking that the lead powders for the deer rounds should be cfe223 and benchmark, pushing the nosler or Sierra 64/65/70 or one of the 60ish monolithic game bullets. For varmints/plinking I'm adding 4166 to the mix but I'm unsure how well it meters as all of my 4166 loads have been manually dropped, bullets I'm considering are the 53 and 60 gr vmax, but I'm open to ideas on all fronts, I also have h322(very fond of its accuracy under a 50 gr pill!) on hand and a2015. I'd look forward to any fast twist ar input. Making a supply run tomorrow so time will be short before I make the initial batches but I appreciate all ongoing input in advance.
Parameters for powder: available and ideally fairly stable, on the worst coyote calling days, it'll be sub 0, on the worst pdog days +100. If I have to do warm and cold loats I CAN but not an ideal choice if avoidable.
For bullets:
Deer: game type bullets, no varmint types, I know some can and do, but for my purposes, they have to hold up through at LEAST one bone through the vitals.
Varmints: hold together in a tight twist, not terribly expensive (very curious about the varmageddons) and preferably fairly splosive on contact.
