More Mosin Loads

I used to not think too much of Mosin Nagant rifles.  They looked cheap, they were crusted with cosmoline, and how good could a rifle be if it was made in Russia and sold at Big 5 for under a hundred bucks?  (That under a hundred bucks thing, incidentally, is no more…prices on these rifles have climbed substantially.)

Then one day after I taught an engineering creativity class at Cal Poly, one of my students approached me to ask if I was a shooter.  He had noticed the 1909 Mauser on my book.

I told him I was and we talked about the Mauser a bit.  He told me that he and his father had recently purchased a Mosin Nagant and they were having a lot of fun with it.  That got my attention for a couple of reasons.  The first reason was that prior to that, I hadn’t spoken with anybody who owned a Mosin.  The second reason was that I always like hearing from young folks who enjoy shooting.  This was a young man who was enjoying the Mosin he and his dad owned.  You don’t hear that too much these days, and I enjoyed the discussion and this young engineering student’s enthusiasm.

The next time I was in a gun store….well, you can guess where this story is going.  I pulled the trigger, and 10 days later, I bought my first Mosin home.

The first time I went to the range with the Mosin, my opinion changed completely.  The rifle was reliable, it was fun to shoot, and wow, it was accurate.  Don’t let a Mosin’s appearance and price fool you.  Trust me on this:  The Russians knew what they were doing.  These are fine rifles.

My Mosin was made in the Soviet Union’s Tula arsenal in 1940 and it has matching serial numbers on the receiver, the butt plate, and the bolt.  The trigger guard/magazine is what we call a forced match.  That means it had a different serial number, but Ivan struck through it and stamped a new serial  number to match the others.  That didn’t concern me at all.  What I worry about are the serial numbers on the bolt and the receiver.  If they match, the headspace is most likely good.  If they don’t, you’ll want to make the seller show you with headspace gages that the headspace is within spec.

I’ve done a bit of work to my Mosin…glass bedding, a trigger job, and a TruOil refinish.  I’ve also done a fair amount of load development (the last time my Mosin saw factory ammo it was in the hands of a Russian soldier; I’ve never shot factory ammo in my Mosin).

My 7.62x54R ammo “go to” accuracy load is 43.7 grains of IMR 4320 under a Hornady 150-grain jacketed bullet.  That load groups exceedingly well at 100 yards.   But that’s when I can find the components I want, and that’s a tough thing to do these days.  IMR 4320 is no longer made and it’s hard to find bullets, primers, and brass.

Fortunately, I have always tended to overbuy components and when I spot a good deal on something I think I can use, I scoop it up.  When the pandemic and civil unrest shortages emerged a couple of years ago, I didn’t feel the impact from a components perspective.  I had plenty of 7.62x54R PRVI brass, I had primers, and I had bullets.  That was two years ago, though, and this is now.  I shot up a lot of what I had, including my Hornady .312-inch diameter jacketed bullets.  But when components were available back in those good old pre-pandemic, pre-Portland-anarchy days, I had spotted a couple of bags of PRVI Partizan 150-grain jacketed bullets.  Being the curious pack rat sort of fellow I am, I bought them.

Most recently, my components dealer had a few powders on the shelves, and I picked up some new propellants.  I wanted to see if I could work up a good load with the PRVI bullets for my Mosin.  One propellant was IMR 4166, which is a powder designed to prevent copper fouling.  I’ve already tried it in a couple of 30 06 loads and I was happy with the results, and I wanted to see how it would do in the Mosin.  Another was Ballsy 2 (that powder is designated BL(C)2, but everybody calls it Ballsy 2).  IMR 4166 is a relatively new powder.  Ballsy 2 has been around for decades, but I had never used it.  When I saw it, I grabbed a couple of bottles.  The time to buy components is when you see them, especially these days.

I also wanted to try my previous accuracy load (43.7 grains of IMR 4320) with the PPU bullets first.  It didn’t take long to load the ammo I wanted…my previous accuracy load with IMR 4320, two load levels of Ballsy 2, and two load levels of IMR 4166.

After charging the cases and seating the PPU bullets, I then labeled the ammo and it was off to the range.

That labeling thing is important.  I always label my ammo as soon as I finish loading it.  I can’t rely on my memory to know what I loaded.

I shot all of my targets at 50 yards as a first look, and I had 10 rounds each.  The first target I shot printed a little low, so I raised the rear sight a couple of notches and that put me in the black.  The Mosin has great sights.

How did I do and what loads worked well?  Here are the targets:

The results from the targets shown here are tabulated below.

The bottom line is that my former accuracy load (with Hornady 150-grain jacketed soft point bullets) didn’t do as well with the PRVI Partizan bullets, but the PRVI bullets shot very well with BL(C)2 and IMR 4166.   That’s good because even though I have a good stash of IMR 4320, it’s no longer in production and the other powders (BL(C)2 and IMR 4166) are available and they are accurate with the PPU bullets.  Good times.

About now you might be wondering…how can I get a Mosin-Nagant rifle?  It’s not as easy as it used to be.  We’re not importing them from Russia like we used to, and you can’t pick them up for cheap at places like Big 5 any more.  I felt they were exceptional bargains at those earlier price levels and I bought several (none are for sale), including a sniper Mosin I’ll write about one of these days.   I checked on Gunbroker.com and you can still find Mosins, but they seem to be starting north of $300 now, and going up sharply from there.  I think they’re still a bargain, even at those prices.
