I have had a couple posts here lately on my new trk rifle. Rebarreled LTR, Rock 1/8x21 1/4" L. Had throated xtra long, 2.405" COAL, seated .010" off lands. Using Lapua .223 brass, CCI BR-4 primers, Hornady 75gr BTHP and currently loading 24.7gr RL-15. This load is .6gr above max in Hornady manual.
My 308 load using Lapua brass and Sierra 175gr BTHP match is nearly 2 gr above max in the Sierra manual. (44.3gr Varget)
I'm not showing any pressure signs whatever on the 223 load. I would like to be shooting at 2800FPS Then this load would have basically the same trajectory as my 308. I plan on increasing my load .2gr to find out where the top is on pressure. I would like to use Varget cause I got so much but my research shows I can't never get to 2800 with it. Any thoughts, opinions, productive comments, especially prior experience with 223 and the 75gr Hornady. Topped it off with the NF 2.5x10x32, It might be a little slow but it is Hell on the farm vermin. krw
