    New VKT M91

    I recently glommed this VKT M91. The rifle is in great shape, metal and wood. The bore looks almost unfired, although I know that it has been fired, because I shot it myself.





    The bore is very tight..I tried a CMPicon .30 cal muzzle gauge and it would not even start in this muzzle, even though it is nominally .3095. A Prvi Partizan 182 gr round gave considerable "stand off".


    Here's the thing..I fired two rounds of Prvi Partizan 182 gr commercial ammo and got considerable primer cratering.

    I have always assumed that this indicated excessive pressure. Anyone have an opinion as to whether this ammo safe in this rifle?

    Thanks

    That is a very nice example, beautiful rifle. The cratering looks like a pressure problem to me also, I would start by trying some different ammo and go from there. When I shoot handloads in my NDM86 the primers will crater when I load 41.5grns of 4064 under a 175grn BTHP but will show no signs of cratering with the same amount of powder under a 168grn BTHP so I think sometimes the line between cratering and not is very small, trying a different load should make a difference. That bore is something else, I'd load some .308s and see if it likes them. Good score!

    I remember hearing that some of these rifles had bores of .308 and not .310. I too suggest you load up some with .308 150 gr bullets and try them out.

    Of course a .3095 won't fit the grooves are .310 or .311. The bore will be about .300"

    Same as a .308 has a bore of .300" and .308" grooves.

    The best answer is to slug the barrel & measure the groove dimensions.

    Thanks, crusty

    I do understand that the bore gauge measures the land-to-land distance. However, it has been my experience that a MN bore, even a Finnishicon one, with appreciable wear will allow the CMPicon gauge to at least enter the barrel. This bore was even tighter than .300-- it would not allow the muzzle gauge to even start in the barrel
