RIMLESS,60 grain Barrier bullet Hornady. 13.1 grains 4198 compressed, RP .223 cases, Wolf primers, oal= 1.745", 2316 to 2424 fps., 1" group at50yds.,
RIMMED, 52 grain FBHP, Berger, 13 grains
T680, PPU cases, Wolf primers, oal=1.850"!!!!, mild, 2328 to 2556 , POI changes dramaticly with velocity difference.
RIMMED, 52 grain FBHP Berger, 13.5 grains T680, PPU cases, Wolf primers, oal=1.850",2503 to 2660 fps. Deadly when velocity is close. As velocity increased the point of impact rose.The differential between 2503fps. and 2660fps. was 1 1/2". The 7 shots fired were true to form in degree.
To this point the loading has been within published .218 Bee data and the pressure indications seem low. Future loading will be gradually stepped up to get some indicated max. loads.

Some time a little of both, plus make a greater effort to clean lube off the cases. Being in wildcats anealing and neck brass thickness have to be considered.

Thanks for the response!!
