Goodsteel put this 20" bbl on an ol' Carcano I've had kicking around for too long. The bbl is 7mm so it is a wildcat sorta , .007 over. The 6.8 data is skinny out there . There's data for 10-15 powders and 50 bullets but next to nothing for boolits. I have dabbled out in nomans land for 1 cartridge but but there was some guidance there for it. It also was not in a platform that I had anywhere near this investment in. I know I could max out the case w/4350 and about any weight boolit fairly safely. I have at the moment 285-130 2R Lee plain based and checked and a 27-130 FN to PP. I've tried 3 loads w/RL 10x under the PP. The top load was very erratic,23gr 2304/2345/2397 the load at 21gr posted 2158,2145,2124.
What I have for powder ,
IMR4350
RL 10x
IMR3031
IMR4895
IMR4756
800x
Unique
Red Dot
Primers in LR standard from CCI and Win.
I really want to shoot this 1 up on the top end w/PP as that is why it was built taking all suggestions though.
I've had success in a couple of 30s w/PP and my technique is sound as far as PP'ing goes . I've also had good luck w/PB boolits in 30s up into the legal big game levels ,1000ftlbs @100yds . This 1 has has been a pleasent suprise so far giving me 2" 50 yd groups right off w/a Reading #070 140 a TC/SIL sort of boolit.
