Use any quality load listed in a good manual for 230 lrn and you should be happy. I used precision's "black bullet" for a while, but the coating in the barrel was more difficult to get out than good old fashioned lead. Still have some in 185 swc. Tracy
I just got 2000 of the 230gr. black bullets myself for the first time. For 230 LRN I like 5.3gr of 231, and with Berry's Plated 230gr. I like 5.6gr. I expect the new ones to take somewhere in this area, but like you I'll work up to it.
A perfect 45 ACP powder, suggest start load of 5.0g, OAL 1.245-1.265" based on your gun (mine go 1.250"ish).
5.0g gives 690-740fps based on specific gun.
I know, I'm shooting 5.0g/230g (FMJ, though) this morning.
Never seen a 5" need more than 5.5g to "make Major".
I notice both of you use a OAL length much shorter than what is considered the max of - 1.275".
Is there a reason you guys set the OAL that much shorter? I was gonna shoot to get the OAL to just under 1.275, when/if I got my Dillon set up tomorrow-- on the Dillon video, they use the 1.275 OAL when they set up the reloader and ended up with something very very close to that- like 1.273 or 4.
I've manufactured more 45 ACP than all but 40 (cops, ay?)
So I've learned from experience what a reliable OAL is, and I offer it to you: from 1.245" up to 1.265" using Rainier 230g TCJ-RN (one of my personal favorite bullets, 'cause I use them meself. IPSC, you know.).
I've gone (way) shorter, and out to 1.275", too, but that was for a specific gun-in-hand-at-the-time.
