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.

That little 125 gr Ballistic Tip is one heck of a deer bullet. Accurate and expands well.

I haven't tried the Accubond version.

Don't know that I can be much help as I have never worked with this cartridge. It poses fascinating possibilities, however. I would think that either the 125 AB or 125 BT would work very well for you.

Which of the two would expand slower?

Here are some pictures of the work in process. I hope the pictures download, I have had some problems downloading pictures here. I just wiped the stock down with some Glycol-Ether to bring the color out for the pictures. By the third picture it started drying out. There is still a lot of sanding and finishing to be done on the furniture.

Here is a picture of the cartridge. The gray one is the surpluss and the brass ones have been made out of a Carcano case (PPU). The bullets are all in the 125gr size with a FMJ, Z-Max and Ballistic Tip. If you can picture it as a 6mm longer 7.62x39 with less case taper. The base is the same size.

From experience with other Accubonds, the Accubond will hang together better, refusing to come apart, but both will expand readily. That's a guess, based on using some larger Accubond bullets. They simply don't come apart. They lose a little weight in the forward section, and mushroom very nicely.

At the modest velocity you're talking, either one should work well. I hunted a lot last year with a 165 grain Ballistic Tip from my .30-06 at about 2900 fps and it performed very well. But that's a heavier bullet, with more punch behind it so I don't know that we can rely too much on that for an example.

The Accubonds I've used truly perform like a bonded bullet is supposed to. The lead & jacket don't separate.

I almost have my first of two small ring Mausers finished for this caliber. I will post some pictures once it is blued and put back together. At which time I will put my Mini Mk-X Mauser up for sale. I also have the 7.62x39 insert which i will include with it for the guys that will want to use it in its original 7.62x39 configuration. The two I am building are both based on small ring Turks. One will be with Williams WGRS peep sights and the other with a 3x9 tactical scope. I'm still waiting for the stock for the scoped version.
