Hello all;
I have been shooting the 7.62x45 Czech since I have bought my first Vz-52 in 1993. At he time, over a period of a few months, when they were available for next to nothing, I bought five. I still have four and the fifth is with my dad. I came to love the cartridge so much that I built a little hunting rifle from a Mini Mk.X action, around 1995. The main drawback is that the cartridge standard length has the bullet set way deep into the cartridge. I have been sitting on a bunch of, both small ring and large ring Mauser actions for many years now and decided to do something with them. I took one of my Turk large rings and built a nice hunting rifle out of it in 8x57 with a new E.R. Shaw barrel. Now I plan on using two of my small ring actions (I have five total) and building hunting rifles in my beloved 7.62x45 It is a fantastic cartridge to shoot. It falls right in between the 7.62x39 Soviet and 7.62x51 NATO. Almost the equal of the 300 Savage but in a much smaller and much more efficient package. I have now dropped a bunch of wild hogs with this cartridge both with the Vz.52 and the Mk.X. However I have always used the FMJ Czech surplus rounds for this. I have never used one of my loads with a "sporting bullet". Many of the hogs I have dropped (I always take bores, never a sow) have had shoulder hide as thick as 2.5" in some cases. With the 7.62-Kr-52 military round (130gr) it is no problem because they have a mild steel case with a armor piercing core. These cut through the pig like butter. I would however like to start using a commercial bullet for this task. My new project rifles, being based on the small ring Mausers do not have the limitations of the short magazine and I can start using longer bullets which do not need to be seated so deeply into the cartridge. Since my love-afire started with the Nosler polymer tipped bullets on my .375 T.R. Magnum and the AccuBond, 260gr Spitzer, I virtually ignore all other bullets but Nosler. My new rifle will have a 3.54" longer barrel (21.75") and I can make the cartridge 2.5" which will by my new "sporting" OAL. I can go with a bullet maybe .025" longer than the #30125 BT 125gr Spitzer which I have started testing. Since my first rifle is not yet finished I can't finalize my tests. So, I guess my question would be; which .308 bullet from Nosler is no longer than 1.1", no heavier than 150gr (nor lighter than 125gr) is a boat-tail and has the greatest penetration? The ones I have been contemplating are the 30125 125gr Spitzer, the 52165 125gr. Spitzer, which are my only Nosler choices with my parameters. MV will be 2700+FpS according to my calculations. Any help would be appreciated. If there are any other suggestions, I will listen to them.
