I just bought a Ruger M77 Mk 2 target in .243 win. I would like to end up with 2 main loads to shoot. One with 65gr vmax or other varmint bullet that will reach 400-500 yards for prarie dogs, coyotes, etc. And one load with a relatively high BC but still a good hunting bullet to use on anything from coyotes to mule deer. I was thinking Berger 95 grain VLD for this?
Powders I have on hand are IMR4831, IMR4064, Varget, Superformance, and H380
bullets I have on hand are 65gr Vmax, 85gr Sierra Gameking bthp, 95gr Berger vld, and 100 grain Hornady Interlock bt
the 95gr vld claims a .486 BC and requires 1 in 9" which is what my bbl is
the heavier berger requires 1 in 8" twist. I do not know what 105 grain Amax (claimed BC .5) needs for twist rate and I dont know if this would work on game anyways.
PS bbl is broke in and has 100 rounds through it with some other varmint bullets that I wanted to use up
The hornady Interlock btsp claims a .405 BC which is pretty impressive for a lead soft point hunting bullet.
Sierra gameking 85gr BC=?
Once I make my initial bullet and powder selection and start loading I will reduce by 10% from shown maximums but what increments should I use to step up the loads? .1 grains .5 grains? I am going for minute of Prairie dog @500yds with the varmint load with max speed, and at least .5moa for the hunting/target round with a reasonable velocity.
