Has anyone had any experience reloading 9 mm for a semi-auto UZI. I need to know if the load data for 9 mm pistols (4-5 inch barrels) is applicable to the UZI with a 16" barral. I am going to load a 115 grain rn from Sierra using power pistol. I understand that I do not want to go under the minimum load as pressures could rise above a safe level. I have found some data specificly for the 16 inch barrel in the new Lyman manual but it only lists a 115 grain hp. How should I adjust this data?:)

I may be wrong, but I don't think you have to adjust a load for a longer barrel. I use 9mm 147 grain rounds in my Kel Tec P11 (3" barrel) and my High Point carbine (16 inch barrel). The velocity is a lot higher in the carbine, but the ammo shoots well out of both.

You should use the same loads for both guns. The 9mm round is an efficient pistol round that does not gain much velocity when fired from a carbine length barrel. The 115 gr. load will add maybe 300 fps from the 16" barrel.

I've seen some specific loads (can't remember if it was here or otherwise, try a search) on "carbine specific" 9mm loads. supposedly he was getting 1700+fps (chronographed) using Blue Dot.
Thanks for all the great advice. My main concern is the load building up too much pressure due to the longer barrel with a starting load. should I start out with a little higher load than the published starting load?
