With the muzzle on a board, drive the slug into the barrel maybe 3-4'. Mash the body lengthwise in the vise to bump it up to about. The easiest wasy to check your barrel's internals is to take a 30 cal cast lubed boolit and cut the nose off, so it's about 3/8' long or so. When Harry Pope was involved with the US Palma team he went to Springfield to oversee the production of thier rifles and was astounded at the bore/groove dimensions they were turning out. Ruger used to buy barrels form an outside source and had accuracy issues. I'm sure they are both within tolerance, and might shoot equally well with FLGC type slugs.Ĭan't be negative about the Argentines though. I will then figure that their barrel manufacturing also lacked 'That little something extra'. While these are really well made, they lack that little extra that sets the German contract rifles apart. Yet they have the barrel discrepancies noted. Nice and shiny, sharp lands, great crowns. I mentioned the German ones as possibly having the tighter barrels as my experience with German rifles is they are generally 'At' or very darn close to what they're supposed to be.īoth my Cav carbines have excellent appearing barrels. 1mauser, mine are Argentine manufacture also. If you can't find any cast boolit data specific to the cartridge, just use 308 data.īTW, the 7.65x53 was Paul Mauser's first cartridge, used in the Belgium and Turk Mausers also (Turks switched to 8x57 later). Only one thing some people consider a negative, is that the caseneck is real short. If you should happen to run across a bunch of cheap 8x57 brass, this is easy to reform to the 7.65x53 as there isn't as much trimming to do as with 30-06.īallistics for the Argentine are very similar to the 308 Winchester and it's a fine cartridge. 312/.313' from their moulds.īrass is no problem, as Graf & Son stocks 7.65x53 headstamped brass for about what 30-06 or 308 brass costs. Also the Lee soupcan C309-113F, as most find it to drop at about. If your groove is smaller you can then also get the Lee C312-185R, which is a nice boolit. 312' (or maybe even smaller?) you can size it down if it won't chamber at. 303x.314' barrel.Īs was mentioned, the Ly 314299 would be a good mould to buy. If yous is German (DWM) manufacture it may well be closer to the.

One of these? I have 2 of'em both Argentine manufacture and both are different in the barrel dimensions.
