H&R MAGNUM CONVERSION

[Hondo44]

I've converted a few Small frame Smiths to 32 H&R Mag. Just about the simplest re-chamber that can be done. So little material is removed it's akin to opening chamber throats to proper size.

The reamer can be turned by hand with a T handle.

In I frame and new I frames, the barrel/cyl gap will be sufficient to compensate for bullets a few thousandths longer than the chambers. Or worse case scenario, bullets need a few thousandths slight deeper seating; either reloads or running factory ammo thru the seating die.

The dash 1 .32s are J frames with about 1/8" spare length in the chambers. There's no strength differences between Post war I frames and J frames.

The rear face of the cyl nor headspace is an issue. Just don't ream deep enough to recess the case rims.

This is my first re-chamber to 32 H&R Mag, a 4" J frame Model 30-1, 1966 vintage:

Others have been snubby Model 30 New I frames.

It's a good thing I'm on my iPad... every time you show that gun I start to salivate so heavily I'm in danger of ruining another keyboard!

It's like a blued pre Model 631, and we all know how desirable they are. I keep telling myself I'm going to build one for myself, but I never seem to get a round tuit.

For those shooting hot 32 H&R Mag loads, especially in a lightweight model such as the 431PD or 432PD keep your eye's open for a new J frame boot grips from Culina. I'm not sure how soon will be released but I did a test for them with 3 J Frame hammerless models, and it is amazing how much less the recoil seems. With the 432PD Airweight (which usually ate my thumb after 2-3 cylinderfulls) I shot 50 rounds without a problem and kept most all the rounds in 3-4" at 12 yards (double action). I won't show any pictures until after the new grip is released.

If you have a lightweight J Frame, these make a difference.

I'm probably going to sound like a Philistine (again) but the set of grips I've found for my favorite J-Frame (a Model 60-4) is a set of Thai combat style grips with closed back made of an ebony type wood. They are as good a fit for me as any grips on any revolver I've ever owned.
