In my first post I forgot to add a couple other details and facts about the .327 Mag .....
The .327M operates at
44K psi or cup, the same as the .30 Carbine (which is 1.290in long - SAAMI).
This new round can also be bored to .308 caliber instead of .311.
A check on T/C barrels available in .327Mag, .32-20Win, as well as .30 Carbine - ALL come in .308 caliber.
I am not bothered by this as I'd rather shoot the .308 projectiles in a singleshot riffle.
Also .327M ammo and brass is VERY HARD to acquire given present market conditions and manufacturing of all ammo "flavors," altho
MidwayUSA is reporting ammo should be available
in March, if not before.
Of course .32H&R brass is easily found, but that round operates at 28K units of pressure (vs 44K).
I have been studying these ALL of these rounds because I want a T/C barrel in the .327Mag.
I even considered trying to swage 7.62X38R brass into a "rimmed" .30Carb casing (sort of) and acquired some of that rare brass (7.62X38R Mosin-Nagamt), but a .308 cal .327Mag is a much easier solution!
Also plan on using 100 and 110 grain .30cal plinker bullets, but 125's and 130's too. Plus .32-20 or .312-cast boolits can be swaged to .309 cal, too.
The overall idea is to create a reloadable SmGame or scrounging set up that can operate at low to medium pressures.
