Hiper velocity Ammo

[Darkstar]

Both the manufacturer as well as the gun store I bought my GSG 1911 from said that I could only run hyper velocity ammunition through my new gun. Is this true? what kind of ammo have you put through yours?

[Microgunner]

I think they probably specified high velocity ammunition for your GSG 1911.

This is due to your pistol being a straight blow back action, as are virtually all .22lr semi auto firearms, and the recoil spring weight is properly chosen for high velocity ammo, the most common type.

Hyper velocity ammo is a high velocity charge with a lighter bullet weight.

You'll most likely find your pistol to be most reliable with high velocity ammunition, and there's no substitute for quality. Buy the best you can afford.

Your pistol may also be reliable with standard velocity and possibly subsonic, although I doubt it.

A recoil spring change could adapt your pistol to run reliably on the lower velocity ammo.

I know 2 people with these pistols and both use plain High Velocity CCI Mini-Mags and I've shot one with Federal High Velocity. Which is the same ammo I use in my Browning Buckmark Camper.

My owner's manual says the GSG1911 was designed for HV (high velocity), and it was adjusted to also use high quality standard velocity ammunition. Mine has digested everything I have fed it, with no problems.

I've found with a bit of tuning most blowback 22s can be adjusted to run regular load ammo as well. In particular polishing rails, slides and such and using final finish 22 fire bore lapping.

Federal bulk should run fine in it....

I've got somewhere around 2000 rounds through mine of whatever was laying around; CCI Mini Mag, Federal Bulk, Fed Auto match, Remington Thunderbolt, Golden Bullet, Winchester, and even some old wildcat.

Seemed like it ate most everything, had some issues with the golden bullet; ftf, which is the catridge, so can't blame the firearm.

I've found the GSG to be very reliable, and reasonably accurate for the $390 w/spare mag, I paid for it.

I just picked up my gsg1911 on friday and took it to the range today to pop its cherry. I tried 5 different types of ammo: Federal Auto Match, Federal American Eagle, CCI Mini Mag, CCI Stinger, and CCI AR Tactical. All of which performed very well. I actually had the best groupings with the American Eagle ammo which is contrary to my experience with this ammo in my rifles (GSG522 and M&P15-22) which both work best with the CCI AR Tactical. I also just purchased the Sig Mosquito which liked the American Eagle but worked best with the Mini Mag.

Just my 2 cents :thumb:

It's been awhile since I posted, my GSG 1911 I sanded the finish off of the lower rail slides with some 1000 grit sand paper used a little gun lube and now it runs like a champ. Everyone who's shot it can't believe how well it shoots.

Well that's cool. A good, inexpensive fix! Well done DS!
