Hello Campers! It's a hot, sunny, humid day here in WNY, I hop y'all are staying cool wherever you are! Just got back from the range, starting to work up a loa for the new '06 (Mossberg) that I was lucky enough to win last spring. The load specs are:
WW cases (new)
CCI 200 primer
16.0 gr. of 2400
Lee 312-185 gr. RNGC
The boolits drop at 0.313", sized them to 0.311" and lubed with Javalina. Initial results were pretty good, 10 shots into 1-1/2" at 50 yards after zeroing the scope. I know that's not stellar but as a starting point, I'll take it! At the least, it tells me that this rifle has potential.
The nose of this boolit is cylindrical, not tapered, and mikes at 0.302". My Alloy is 94-3-3, essentially COWW with 2% tin added, though I mixed this from pure lead, lino and 50-50 solder. The nose engravs heavily when chambering the round, but will extract with a bit of a bump rearward without pulling the boolit. Neither does it telescope into the case upon loading. I use a Lyman "M" die to prep the case mouth and I straighten the flare (no crimp) with a Lee Factory Crimp Die.
So, everything works pretty well except for that stiff push needed to chamber the round. I've heard of nose-sizing dies, haven't done any research on it, but would like to get some opinions from you guys about it. Also, Micrometer Seating Die - yes, no maybe? Can you make a recommendation? Thanks for your input!
