Hey guys,

I'm hoping to get "in tune" with a mosin 91/30 I picked up from MrClark. (Thanks :)). Anyhow, I've found the czech and polish surplus I have shoot about 5-6inch high. The Bell stuff I shot was spot on for elevation and they were 148 g SP.

Anyhooo...I looking at working up a load for this, I tried some 168 c CMJ Frontiers behind 45.5 g of IMR 4064 and it too is about 5 " high at 100 m.

I'm looking at trying some 1 g increments of WC735 (5% less than H335) starting at 44 g and 41.5G of IMR 4064 at 1 g increments. Maxed out at 48 and 44.5g respectively.

My question is...have you guys any good loads for your milsurp Mosin's you'd like to share.

I'm hoping to add a mix to the EOHC and Smiths Falls Milsurp shoots.

There has to be someone else in the top 5 crowd not holding a Garand or Enfield, (excluding beer bellies and M17's)

And yes Andy, you did do good with the Swede the first year... ;)
 
I'm still waiting on my dies, ordered them about two weeks ago. Be happy to share my experiences once they start! :)
My issue is availability of .310 bullets. I have a box of Sierra .311 match HPBT (174 Grain) that I would like to try but I would really like some feed back of how the Mosin Nagant handles a .311 bullet. I have talked with a guy in P&D while I was in there who reloads for his Mosin and he stated that the .308 bullets were all over the paper, he is the one who put me on to these .311 bullets.
I bought them due to the fact I was in Edmonton and that is all that I could find. I'd do the research and decide if I would use them later (I live in Ft McMurray, a ways to drive for re-loading supplies). Well the internet has let me down... I got about 50% of the sites saying that a .308 bullet is the best and .311 is dangerous and the other 50% of the sites saying that .308 is loose and inaccurate and the Mosin bore is .311 to .312 and a .310 - .311 bullet works the best. Does anyone have any insight and a good reloading site that I can get some 7.62X54 reloading basics?
(Sorry to hijack your thread, it was related.)
 
Well, maybe someone can tell us how to slug our barrels and then your bullet size question would be answered. I thought they were good to go with 308....
 
I played that game with the Nagant, and am the wiser.

The Eastern Bloc 7.62 x 54R is .311 dia. You are correct in purchasing those bullets. Your buddy did not leave you astray. The.303 British is the same bullet matter or factly. (I said bullet - NOT brass or "round" so get your hands away from the keyboard!!)

The .308 dia is to small. You will have to crimp the bullet because it won't seat very tight in your brass. The finished round will cycle & shoot, put you will never group. The weiner down the hallway effect, if you get my meaning.

When they introduced the 7.62 x 39 to the North American market, they too were .311. Now that they are popular (and cheap), newer versions may indeed be .308 - THATS the stuff you got to be careful of.

Hope that helps

I'll also take pointers on how to raise the front sight as well....
Click to expand...

Typically, if you are shooting "High", you raise your rear sight. If you can't raise your rear sight any further, you file a minimal amount off your front sight.

They only reason you would add or raise your front sight is of your shooting really low. and you cant lower your rear sight any further.

If you elevate your rear sight, you are RAISING your point of impact.
When your rear sight is flat down and cannot go lower and you still get a high point of impact, you'll have to replace your front post by a higher one in order to LOWER the point of impact some more.
As for bullet diameters, it all depends on where your Nagant comes from. Finn Nagants have at least three bore diameters A, B and C .
So called "D" stamp is to denote an enlarged throat to accomodate "D" bullets.
Finnish captured rifles with the original Russian barrels still have the original .310/.311 bore.
Best method to be sure of what you have is to "slug" the lubricated barrel with a soft lead ball or fishing sinker and measure the diameter of the deformed ball.

Well damn... I slugged the barrel and my caliper only reads to two decimal places, (digital). And it is so accurate it measures a 308, 7.62 and all my 303 bulltets as 0.30.

The slug measured 0.30
 
Well I may pick up another front sight and give that a go.

Ah yes Princess Auto....that is where I got the first one for $15. I guess I should have spent $5 more..

Thanks :)
 
Damn Princess Auto...

I got the calipher and new rotary tool ($10.88 with case and attachments - got one already but at $10.88!!) and some generic epoxy ($3.99).

Anyhooo... I slugged the barrel with a lead sinker. I got 0.308 on the land and 0.311 on the groove...

Sounds like I should be using 303 or 7.62 bullets..
 
Well I found http://7.62x54r.net/ and it answered all my questions...

Looks like I'll try some 0.3105 and 0.310 :)
 
That sure is a nice diagram SKS - but keep in mind that Mosin bores are known to vary in size from one to another (athough they are all generally thought to be a bit oversized from the official 7.62X54R measurement of .310 that most reloading guides give).

Mine mics at 3.124 (bore groove to groove) - so at least I know I can use .312 Hornady Lee Enfield bullets for reloading. Others however will vary. Even the Lee reloading guide (Modern Reloading 1st Edition) recommends that individual bores be slugged to determine size.
