Rechambering???

BigFiveJackRechambering???
If one has a nine pound .375 - 2.5 inch flanged D/R, and
the firing pins are far enough apart that the chambers
for the
.375 Flanged MAG CAN fit, is there a
MECHANICAL reason to
NOT do such a rechambering?

500NCan't see a Mechanical reason but I can see
a safety reason.

peterdkas long as you get the gun through reproof, no problem, if not big problem.

WillAussies are just wimps!
Make up your mind. Doubles are such "low pressure," and all that implies. If the Flanged Magnum is loaded to the same pressure, what difference does it make? Ignore any differences in wall thickness!

Up yours as well !
Why do Purdey, H&H et al build the Fl Mag on a reinforced action but not the 2.5".
Maybe because they knew something about what was required.
There are enough rechambered C&H 2.5's floating around the US
to know alot were done just for the money.

WillI'm just harrassing you. I have no intention of doing anything related to rechambering a double .... but one could admit that these doubles at times take on a degree of unjustified mythical status.

Like "they have to be low pressure, but it is perfectly okay to shoot 375 H&H rounds in them," etc., etc.

LJSI was told by Champlins that usually 2 1/2" guns have a slender barrel that would be too thin to accommodate the 375 Flanged conversion. Most 2 1/2" guns I've seen are very light.

JudgeGI took a .375 2.5" double to Africa and had a ball with it. I shot the old Hornady's 270 grain bullets (given to me by Mims that were a part of George Hoffman's estate). I think they were going 2150 fps or so. The killed every thing smaller than a buffalo quite dead with one shot and nothing but a stumble of a few yards.
I always had a few 300 grain solid bullets with me loaded to 1950. I reckon they could have done a little better than the traditional .405 Winchester load as to penetration, but never used them except on paper. That load was very accurate.
Personally, I'd never rechamber the .375 2.5" because it does exactly what it was designed to do.
JudgeG ... just counting time 'til I am again finding balm in Gilead chilled out somewhere in the Selous.

BigFiveJackWhen I used the word mechanical I was thinking physical,
safety, tolerances, etc, just NOT monetary
