Update...

First of all It was way to easy to work up a load for my Kimber. It seems to like everything I feed it. I have SUB .5" groups with both Magnum and RL22.

RL22 We tried a load we developed for my friends 300. Tightest 3 shot group I have ever had at .18"

Magnum powder I just picked a powder weight and loaded it up. Used most of the. For barrel break in but then shot a .20 4 shot group 5th shot turned it into a .47" group.

I am blown away and beside myself excited about the performance of this rifle.

I went down today for the final sight in and when done shot 2 5 shot groups. One with each case weight.

Results.

214 grain case
Group was .45"

215 grain case
Group was .47"


Center of groups was approximately .75" apart. Still acceptable but a noticeable difference for sure.
