Re: Anybody loading 220 SMKs over reloader 22? 300 win
Win brass annealed, Fed 215M primers, 72 grains of RE22,
3.50 COAL, ~.012 off the lands, 2812 fps at 50 degrees from Lilja 27.75" 3 groove 1:10 twist.
~12 min elev at 600 yards, ~28 min at 1000 yards.
Hope that helps.
BTW.....
70.7 grains of H4831SC provides the same stats.

69.5grs. of RL22 with a 220gr. bullet gets me 2775 fps from a 26.5" bbl. Not the fastest but is very accurate. I noramlly settle on the load that gets me really good accuracy instead of seeing if I can get a few more fps.

Good news! I loaded 3 rounds each of 67, 68, 69, 69.5, 70, 70.5, 71, 71.5, 71.8, and 72 . Smk 220s over rl22 in win cases. should be a good first day. Merry Christmas!

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: REELDOC</div><div class="ubbcode-body">What OAL are you loading to? Did you back off the lands? </div></div>Coal is 3.54", ogive is 2.97" kissing the lands, ie when I chamber a dummy round I get one groove mark. So does it make sense to back off the lands a little and look for a bigger powder charge?
Thanks!
