Hello folks, I bought this Beretta model 81BB recently exclusively to convert to 32NAA. My goal is to match its grouping abilities to a 32NAA casing loaded with Lehigh 55g all copper defense bullets. For now, this is what the used M81 can do at 30 feet shooting off a wooded 4X4 block as a frame rest. Prior to the rechambering, the average speed of some pretty old PMC 71g FMJ loads were 962 fps out of the 10 round string. The PPU averaged 914 fps.
To do a conversion on a Beretta Model 81, it simply requires renting the reamer from 4D rentals for a total cost of $47 bucks, adding a model 84 380 magazine and some ammo. No other mods are needed since Beretta uses the same bolt face in their 81/84 model slides. The thick gripped Beretta is a most comfortable gun to shoot. In 32ACP its a real kitten. Stepped up to the new chambering and you know immediately, this aint your grandfathers ACP! The 80g Defensive HP's stepped out at an average of 1067fps in the pictured 10 shot string. I'm looking forward to see what kind of velocities I can generate with the 55g Lehigh copper pills. They should have some serious splash out of the Beretta's 4 3/4" barrel. Then I couldn't help giving the Guardian a go at the 30 foot target with the PMC's. There is some evidence of slight key holeing out of the Guardians shallow rifling but hitting the paper regularly at that range with those sights is still acceptable in my view. ;D
