Today was day one with the 108 grn, Hohenstein, started my test at 200 yards, with H-4350, tried 5 loads and 39.5 grn. @ .005" and .008" into the lands both shot 1/4 moa for 5 shot groups at 3084 Av. and 3076 Av. in my 27" 1-8 Krieger. 39.8 and 40.0 grains opened up.
I will load up 39.3, and 39.0 at the same jam and test next week, (I avoid the range on weekends)! If they don't do any better, 39.5 it will be and I will start playing with other seating depths. But if 1/4 moa. will hold out to 600,,,, 1.5" groups at 600 yards will win most of the matches where I shoot!
I just started shooting Kenny's 68 grn. dbl. ogive BT's in my PPC for BR competition about 4 weeks ago, and 100 yard .068" is my best to date with a couple others in the 0.0's, a lot in the low .1's when I do my job. Only been using them for a month now, and with his 108's shooting like they did today,,,,,, I'll definitely suggest them!
