Cartridges for semi-auto


Recommended Posts

Hi, I just acquired a very nice Beretta A301, my first semi-auto... the guy I got it off said it cycles any cartridges, but I've read that some can be fussy with cartridges ?

 

I currently use Llyalvale 67mm fibres in my Winchester 101 XTR, both 28g 7.5's and 30g 6's and Ely select 28g 7.5's

 

Would I be better getting 70mm cartridges in the future for compatibility with both guns, or will this older Beretta be fine with what I already use ? Maybe someone else who has this gun could advise on what pretty much works reliably?

 

 

 

Thanks

I have 2 collections of Beretta 300 series, one in italy (with about 9 guns-barrels combinations) and on in UK with 3 guns and 5 barrels

 

I shoot anything from 65mm to 76mm ... all in their right chambers (70 mm or 76 mm) with no issues.

 

Couple of points i want to clarify:

 

- you might have issues shooting 65mm in a 76 mm barrel, this is becuase the pressure tends to drop a bit and the powder won't generate sufficient gases

- i reload all my cartridges so, i teend to prefer slightly higher pressures which might help.

 

I had issues with my 76mm chambered barrell using gamebores 67 mm 25 g shots .... but i put that down as my errro; shooting 28 g i had no issues

I use a 303 auto, I use most things through it really, the only cartridges that I have had the OCCASIONAL jam with, have been Hull Comp X. I bought them to use in my O/U and had a couple of boxes in my bag. The gun will also cycle 24 gram Cheddites without a hitch. I used the Comp X's by putting a Superfast in the chamber and the Comp X in the magazine, no problems then.

I know a few people who wont shoot express in their beretta semi autos. No experience of this though.

I only use Express Sporting in my SX3 and when out at clays the other week my mate a Beretta semi auto owner ran out of shells, gave him 10 of mine and he hit a 10-10.

He will not be shooting Express Sporting again, not at my expense anyway.

Comp X is a nice soft shooting shell but not that great in some semi auto's in my experience.

I must say that the 390 I use hasn't failed with any cartridges that I've put through it or any combination. The 300 series are largely the same throughout.

A light 21g comp x is almost recoil free so may not cycle. I don't think I've tried them.

Anything 67mm and above has gone through without issue. In the 6 plus years I've had it I can honestly say it's jammed less than 5 times and thats due to me being lazy and not cleaning it when I should.

A wipe with an oily cloth goes a very long way.

Use whatever carts you have and you'll find out.

It's a few years since I shot an auto on a regular basis.

 

Used many makes of shells, but the common denominator for any jamming / misfire was the length of the brass. Low brass - potential misfire - whereas higher brass - no jams / misfires.

OK thanks for the good info :-)

 

I looked at the Lyalvale carts I had been using in my Winchester O/U, they are 30G#6 65mm and are noticably smaller than the 70mm ones. The 28G#7.5's I have are 70 mm

 

I just bought some Pigeon Power 29G#6 70mm for the Beretta, I'll just use the short ones in the Winchester until they're used up, then just stick to 70mm as both guns can use them.

I've heard a few reports of the older auto's stripping off the brass which causes a jam but not with the likes of the A400, A350. I have no idea why this might be?
