I am tired of throwing 13$ per 100 bullets down range for fire form and punching holes in paper. Cast bullets will poke holes in paper and not bounce off I'm pretty sure; even tho I haven't tried it yet. But will cast loads generate enough pressure to fireform ? I know you can get enough pressure but would you then be driving the bullets too fast. My contender manual doesn't list any pressure data. It also doesn't list any cast loads for the 6mm TCU. All the cast loads are between 80% to 100% of there counter part same weight jacketed bullet load. And I also figuer that any safe cast load in 223 would be ok in the larger 6mm bore. From this I GUESS for an 85grain cast starting loads of eighteen grains for IMR4198; and twentyfour grains IMR4895. Am I even close or is there something wrong with my logic ? Is 2000 fps too fast for cast that is my guess of the velocity of above loads. Does anyone have any Cast data for 6TCU ? Should I work with cast in 7x30 waters first which I have data for to gain experiance ? (I don't need any more fire form inthe waters and dont shoot it as much) Or should I not be cheap give these barrels their perfect less than MOA ammo all the time?( the old it aint broke so don't fix it) Thanks for any info JR
