Model 25-2 .45 ACP factory throat diameter questions

[TheTinMan]

I have seen throats on these guns as large as .458 and they pattern like a shotgun. Your caliper measurement is most likely off by 1 or 2 thousandths. I have also found that shooting jacketed or plated bullets can give excellent accuracy even with oversized throats.

Plated bullets are reasonably accurate in my 25-2. Lead bullets were a mess both on the target and in the barrel.

Without digging up my notes I can’t remember what the throat diameters were, but I do remember that they were over-sized and not consistent.
