I recently started reloading and shooting rounds for my 24/7 Pro Compact DS .45acp
I've used the following recipe on two batches:
Projectile: Missouri Bullet Company - 230 LRN "softball" .452, BHN=18*
Brass: Assorted between PMC once fired and Winchester, Remington, Speer Range brass (all cleaned up of course)
Powder: Red Dot
Charge: 5.0gr and 4.5 gr
Primers: CCI 300
OAL: 1.265
All rounds go into battery and feed from the clips without a hiccup. When dropped a dummy round into the barrel (removed from the gun) it seats flush with a 'clunk'.
After shooting 50 rounds of each this past weekend, my barrel was so leaded, grooves were almost FULL of lead. It looked like I had a smooth bore! In fact, there were very small thin shavings of lead clinging to the inside of the barrel.
I've got it all cleaned up now and all the lead is gone, but I have a LOT of these bullets left over.
I'm wondering if the following could be a culprit:
1) BHN is 18: Is this too hard of lead for my barrel?
2) Barrel could possibly be .001-.002 larger than .450 - has anyone slugged this barrel? I haven't yet, but plan on doing so. The reason I bring this up is that gas cutting could be the culprit.
3) Could my OAL be too short? I measured against a PMC 230J FMJ for seating depth, after I had shot 150 rounds of that ammo without a single failure to feed/fire or jam.
4) I did NOT check the diameter of the projectiles against a caliper. I assumed (yes I know what that means) that they were spot on as .452 since they were professionally manufactured.
Thanks in advance.
