Good Afternoon and thank you for providing such a wealth of knowledge on this forum. I am looking to pick up a new mold that would work well in both 30 carbine and 300BLK. The 300BLK will be used for supers in an 8.5″ with CFE BLK and a RAA rifle for subs suppressed with trailboss. Projectiles will also be tumble powder coated. I have had great luck with the 311-232-FN-AZ1 BLKOUT when coated but thats way to heavy for the 30 carbine. I think I have settle between these two mold HTC310-135-RN-BY3 5 cavity PB and HTC312-137-RN-CA1 5 cavity PB. I have the HTC452-234-RN-BV5 and love how the fly out of the mold when casting and since I’m coating them I would like to stick with one of the HTC molds for this application as well. Thanks for any input and advice on these two and have a great day!

The 30 carbine is going to want a 110-120 grain “Round nosed” profile, or your asking for Feeding issues!
I had a ton of the “Berry’s Plated 110 grain, that I loaded in My M1 Carb. [Sold many moons ago :'(] so just to see, and to use them up, I loaded a bunch in 300 blk. I don’t have my notes handy, but they were all supers, and functioned perfectly, but the powder I was using, 4227(I think) was the problem, in that they were shooting “dirty” and after a hundred or so, a case got stuck enough for the Extractor to rip out the Rim, but a cleaning rod pushed the case out with little resistence. But the “Round nose” fed Fine in “My” upper.
Hope this helps you make a more informed choice, but that M1 Carbine won’t “like” anything but a “Traditional” “Ball” ROUND nosed bullet, I guarantee it! Good luck, and let us know what you come up with!
