Boolits in a MN 91/30 info wanted!!!

[seagiant]

Hi,
I just did a search for opinions on a cast boolit and or mold for my MN 91/30. I did not find to much surprisingly! What are you guy's using for boolits in these rifles and also interested in bore sizes you have and any other info on this rifle in reloading! Thanks!

[Dutch4122]

Best advice I can give you is to go to the "Active Group Buy" sub-forum. Swede Nelson has run another Group Buy for the NOE 316299. Ask him if it's too late to get in on that one. The 316299 drops .316" on the body bands and .305" on the nose.

If it's too late to get your order in there; then keep an eye on the "Vendor Sponsor Sales" sub-forum. He usually has a few extras for sale after the Group Buys have shipped out.

Hope this helps,

Hi Dutch,
Thanks,if that mold drops a .316 boolit how far down would it have to be sized? I'm not at home now and have not slugged the throat/barrel on my MN. I'll check the mold out,thanks again!

Ok, I found some info ,it seems most of these are around .313 bore dia. So adding .001 that would be a sized boolit to .314 Does that sound right? Also thast would make the .316 with a .305 nose work pretty good!

[Dutch4122]

Instead of slugging the bore and throat you can try another method. Take a casing that has been fired in your rifle, but has not been resized yet. Measure the inside of the case neck with the small end of your calipers. Subtract .001" from that measurement; and that will be the largest diameter cast boolit your rifle can safely chamber and fire. So, if it measures .316" then you would size to .315" and so on. Remember that this method is case brand specific; as different brands of brass will have different case neck thicknesses.

Mosin bores and throats are all over the place. That's why I use the method above. No two M/N's are the same. I have a 91/59 carbine that slugs @ .315" believe it or not; and others have reported bores as large as .318"!

Hope this helps, :D

Mosins and Lee Enfields alike! I have a latter with a groove of .318/.319 and a bore of .308! I don't know about the Mosin but mine has a normal chamber, That means a good groove fit is also a good neck fit without resizing and that's what I do. My policy is to use as fat a boolit as will enter the throat (and seat in an unsized neck). It's a lead boolit so I'm not concerned about case neck expansion to release the boolit. It'll push out regardless. One of my guns has such a large throat that the loaded cartridge has no neck clearance at all and I have to work to get enough pressure to burn the powder properly.

Thanks Gentlemen,
Still looking for info on these rifles!!!

These rifles will shoot a cast boolit very well the trick is to get a boolit fat enough to fit the throat and groove diameter of the barrel. Another consideration is to expand the neck of the case big enough so that the oversized boolits will fit the case. A Lyman "M" die does this pretty well although there are other ways to do this I prefer to modify my dies so that I don't over work precious brass.

Hi Richard,
I'm all ears! Whats the mod???

[rhbrink]

The RCBS dies that I bought for my Mosin were made to resize the case for .308 jacket bullets they did include a larger expander that did open the case up a bit more but no where enough to load and shoot a .316 diameter boolit. So I had the neck portion of the resize die ground out to .338 which works just great for my big boolit. Some people like the Lee collet dies but you have to get a bigger mandrel (I think is the name for the part) to resize to the proper tension. Also you can get a Redding bushing die for the .284 Win. case and get some bushings for different sizing options. To use the .284 die you do have to trim a bit off the bottom of the die to get the neck portion of the case far enough up into the bushing to work. A dremmel tool works just fine for that. For my money the bushing die is the way to go, lots of options if you load for several Mosins. And if you have one you'll soon have more you just will not be able to help yourself they just follow you home. A good thing is it seems that brass is getting easier to find reloadable brass that is.

Good luck

My 91/30 (Tula '39) slugs at .313 (grove) x .309 (bore) and, for casual paper-punching out to 200M, likes the Lee 312-155-2R sized to .315. (Mould has been beagled to drop a bit over .316).

Thanks Gentlemen,
I was able to get into the NOE 316299 mold GB by the skin of my teeth (Thanks Swede) so hope to have a nice mold to use when I return in Jan. from work! Will try to post back then and report what I have found for us Mosin Nagant shooters!

I improvised a Ranch Dog bullet in 303 British that performed good in my sporterized No.4 Enfield. The TLC-311-165-RF bullet is intended for 30-30s but, my mold drops them at 312.5 and I size them to 312 for the 303. I do want to try this in my 91/30 with the 7.62X54R and 303 being so close it may do well. I also plan to try the CTL-312-160-2R that I use in 7.62X39 for my SKS.

I'm using 155 Gr Lee boolit (WW alloy),13,5 Gr of Promo/Red Dot in Lapua cases with Win primers.
Works excellent.

[jcunruh]

I'm using the lee 155's sized at .312 w/ GC (bore is .311 grove .308 bore) on top of 20gr of 2400, groups are a little over an inch at 100yd. I have some of surplus Russian 2400 that's floating around and find that 24gr. Does about the same velocity just picked up some 5477 but have yet to start load development

What kind of accuracy do you get out of these rifles? I see one selling localy for $150.00 and was wondering if it is worth it. It is a made in 1932 hex reciever all numbers match in good condition.

[Donor8x56r]

I'm getting 2 inch groups with above mentioned load with fliers opening it up to 3 inches.
I have to pay a little closer attention to my casts :)

btw-I'm shooting M91 Mosin made in Tula(I think) in 1899 with VKT 1941 made and later counterbored barrel.
Rifle is totally mismatched (literally).

I have only this to say about that hex reciever M/N. GRAB ONTO TO IT!Robert

SAECO 305 works well in mine, unsized, no gas check, tumble lubed, IMR 4350 + enough COW to be compressed a bit. 1900 fps, around 2 MOA accuracy.
