    @jim160 mate im sorry i haven't seen this post, probably best in some respects this is my first 24hrs in months with NO meds....... so hang on with any ramblings....

    so, rifle that i used in this project was / is a single shot omark, I had a little removed from the end, threaded and a Gunworks maximus suppressor made up for it. Love Omarks and for the purest, ive saved a fair few over the years and this one was never going to be a target rifle again....i digress, but ive just found some reloading 2B4 old reloading notebooks so.....

    the following is only around the subsonic development, my goal was to create a hard hitting accurate quiet round,

    Powders that ive tried, 2206H, Alliant 2400, Trailboss, 700x wow a raft of them, found the 2400 lethal with a Carcano 6.5 with lead cast projectiles, the 308, it was trail boss!

    Cast projectile weight ranged from 208Gr looks as if i sized to .312 of which with a very classic annoyed handwriting "with much annoyance, ive realised ive not properly written down the previous top load" "the author is a poor recorder of loads, an idiot"..............which makes me laugh, and a little cry as from what i can tell i was making a 224gr projectile sized .310 GC with wool filler, with 9gr trail boss another with 12gr of 2204 i know one was super quiet and more than adequately accurate, how so i made up a box of 50, and am now down to only a couple, owell ill be more attentive!

    i also found a load for a 150rn sized to 310, notation = "quiet, very accurate" was with a filler, possibly with flared case 1430,1418,1407,1385, 1399fps

    i will keep looking and see what moulds i was using, i know i was even making my own gas checks, my go to guru was / is The Cast Bullet Kid, jeff is truely a legend! in fact i may bug him next now that im able too!

    ramblings done!
