I'm just getting into shooting plain base boolits from my '06 and was wondering what kind of results others are obtaining.
So far, my results aren't anything to write home about (< 2MOA) but I don't see why my '06 shouldn't do as well as .22 match ammo if I can find the right combination. I'm using 4759 and alloys just about the same hardness as Lyman #2 or a bit softer. I don't want to use alloys much softer due to the likelihood of deformation in the loading process. I've got a mold cut by MM that casts in the 195-200 grain range (depending on casting temp and alloy) but am contemplating a 180 grain design to be cut by Accurate. The MM castings have a 0.2" meplat, 0.43" ogive, 0.16" leading band (to fill the throat), 3 lube grooves of approx. equal length and a 0.12 or 0.13 (IIRC) long base. The overall length of the boolits are 1.08". Perhaps I'll post a pic of the boolits if I get a round-to-it.
So far, the 180 grain design on the drawing board has two lube grooves and a .14" long base which I'm thinking about making even longer (perhaps .15 or .16). It's also got a .190 meplat and a secant ogive which should move the CG toward the base a bit farther.
