Mini 14 Tactical, IMR 4198, 52gr BTHP
Tried out some new loads today. <20 grains of IMR 4198 wit a 52 grain Hornady Match grade BTHP, and CCI 400 primers. These grouped a little better than my H4895 loads, but about 1/2 or the rounds either short cycled the action or didn't cycle and eject at all.
I also had some 68 grain BTHP Untramax rounds with me and they grouped the best with several 3 round groups under 3 inches. I would think the lighter rounds would group better than the heavier and longer 68gr, expecially from the 1in9 Mini.
My hope was to work up a load for 52-53-55gr bullets using the IMR powder. I've got 500 Remington PSP 55 gr flat based bullets ready and waiting. So.....,my question is......................
(1) What experience does everyone have with Flat base vs Boat tail rounds with the Mini. Is one more accurate than the other. I have read that the Mini likes flat based bullets and is more accurate with them.
(2) Are 55 grain bullets the upper limit when using IMR 4198?
(3) What have you found to be your most accurate combo of powder/bullet/primer for your mini?
Perfect is the enemy of good.
