Title: Rim Rock 220gr - Powder type /OAL / powder Work up range
Post by: Kenk on February 25 2018 09:10:42 AM MST

Morning Folks,
Once my Rim Rock 220gr FP's arrive, I could use some recommendations / advice on the following. I have 3 powder options on hand; Blue Dot, Long Shot, and Powder Pistol. In addition, I am not finding much on a min-max charge range for this weight projectile. Lastly, for my OAL, I'm guessing it should be around 1.24-1.25
I will be using a G20, gen 4 with a factory length KKM barrel.
Any thoughts on the above would be very helpful
Thanks

Ken

UW is loading Longshot 8.0 - 8.6 with the 220 bullets 1.2520 -1.2660"
DT is loading Longshot 7.2 with the 230 bullets 1.2550
BB is loading Power Pistol 8.4 grains for the 1.2550"

Some of the 200 grain loadings show 1.2420" COL

If you load shorter than what is listed you may want to reduce charge weights...
