Ammo for Interarms Mauser

unspellable · 08-27-2003, 10:48 AM

How many rounds have you put through it? Unless it's really bad, I'd allow 200 rounds as a break in period before I started really worrying about reliability. My standard for a reliable new bought pistol is to ignore the first 200 rounds and tolerate no malfunctions in the second 200.

I'd make an exception in the first 200 rounds if it has obvious problems. I might tolerate one malfunction in the second 200 rounds if it's a for fun pistol as opposed to one for social occasions.

And if there are problems, then you are correct in not overlooking the possibility that the ammo is the problem.

If its a 7.65, the factory ammo will be under loaded. Fiocchi produces the lowest velocity, Winchester the next lowest. I have not run Remington/Peters over the chronograph yet but suspect it is the hottest load if you can find it. You are looking for high velocity, not high pressure. It's a recoil operated action, not a blow back.

If it's a 9 mm the factory ammo will be too short. Try the Wally World Winchester hardball special. It's has the longest OAL of any factory load I know of off hand.

(Really bad is defined by an AMT 380 I had that averaged 2.5 malfunctions per magazine load including such wonders as tossing a loaded cartridge out in front of me.)
