I finally finished my 1.40" 41 Magnum project (formed from cut-down 414 SuperMag):
Some details include:
- Stainless Bisley with a 6" Pac Nor barrel. - 5-shot cylinder - Bowen Target rear with a home-made aluminum front post. - #5 basepin - For contrast I used a blued Bisley hammer and trigger combo - Action tuned to 2.5 lbs - Laminate Hunter grips; though I'll probably have Cary Chapman do a set of Claro Walnut in time
Here's what the 5-shot cylinder looks like:
Once the snow melts, I'll put it over the chrono (we got 18" over the weekend). I'll also publish load data since I know a few others will be working with the round.
Turned out nice Lee.... I'm still waiting on mine. You will have to share your load development trials... Don't we have a forum member with a Harton 1.4 41 mag? I think that Alan provided some data too...
Lee - what OAL will yours handle? Alan told me mine is going to handle up to about 1.877 OAL cartridges with my rebored maximum cylinder.
Mine will handle 1.85". Haven't chrono'd this one yet, but my 401 Bobcat is pretty much the same cartridge in 10mm. From a 6-shot, it'll do 150 fps over a 41 Magnum. As a five-shot loaded to 50,000 - 55,000 PSI, this should yield 200 - 300 fps over a standard 41.

Not sure I can hit 1,900 fps with 185s. Most of these 5-shots give better velocity gains with heavy bullets. In fact, this conversion will probably see nothing lighter than 230 grain Keiths. Most of what I'll shoot will be in the 265 - 295 weight range.
