1lb 10 oz

i have 1 170, 1 155 and 3 140s....gonna add another 170 and 155 eventually

it measures out to 0.376...might look weird in the pic... i made 10 oal dummy rounds...all measure with in 002 oal all plunk and spin with the crimp at 376

This is my second profile/try....my first was coated lead that i had laying around from minor and that was like a shotgun grouping and too many variances in oal, ogive etc so now I'm trying the 124PD that I've seen as a very popular projectile. This is one of my few mock-up OAL rounds. doesn't look like it would compress the load. i could start at like 9.0 and work my way up and see what happens over the chrono this weekend.

I picked up a CK Thunder with the kkm barrel over black Friday and I'm working up a load with AA7. Im finding out that the max OAL is 1.145 during a plunk and spin test. Crimp is .376. searching the forums here I've seen quite a few posts about their OAL being 1.165 with the PD124s in 9 major. Do I work up a load with the 1.145 OAL and send it? or should I send this barrel off to be reamed to be able to accept the 1.165?

the 171s after crimp etc did acutally plunk and spun in the barrel....so i have 50 more rounds now....same seating die setting varying from 1.160-1.171

9.5 gr of aa7 Brass lube lubed cases If i shorten the long ones down the 163-165s will be below 1.160 and being that its major i dont want excessive pressure spikes

i have a mark7 650 pro Lee seating and crimp die 125gr gallant coated lead bullet mixed cleaned range brass my target is 1.165 and most come in a 1.163-1.165 but then I get some that are 1.171 and its absolutely driving me nuts..... 29 round test batch 5 were too long at the 1.17 mark.... ive checked shell plate, cleaned the die, readjusted the die, measured a handful of projectiles and they all are within .003 Any suggestions?
