The bullets were .452 lead bullets from Houston Bullet Co. No hardness available. The barrel will be slugged in the next few days to see what it is. We are not talking squibs, the bullets hit the target (and one bounced off). The firing from the glock confirmed the loads were functioning. The low velocity happened with 6 shots with the lead bullets using 2 different powders. I think that the compatibility of the lead with my barrel is the most likely reason. Liontribe- I understand about the Glock and lead, and informed the gun owner about the need to clean and risks before we tried it. We fired only one from the same batch of loads, it chronoed 824fps. Thanks for the reminder. Appreciate the ideas. it helps me to keep thinking and learning.

I have a Tanfoglio Witness Polymer Compact in .45ACP. I would like some help deciphering this situation that happened tonight. Loading Once-fired 45ACP brass with 4.0gr Titegroup, with a lead 200 grain semi-wadcutter. OAL 1.225 Chronograph from my gun gave 450 fps instead of the expected 800 fps. 230 grain FMJ used to check chronograph out of same gun gave 924 fps (intentionally hot load). Next lead bullet gave 454 fps. Same lead bullet and load out of a Glock 45 gave 824fps. Gun has about 800 rounds through it. All jacketed bullets give good performance. Any ideas? Thanks for the help.
