hi all,i've just bought a new beretta 391 ulrika camo 3 inch,the instruction manual says it can handle upto 56 gram load yet it is stamped kg 1,070 on the barrel,i bought some itm 50 gram cartridges today and on the box it says for guns with 1,200kg,the proof mark on the barrel seems low to me for a 3" chamber,does anyone have info on whats safe to use,
thanks andrew.
