Some may recall a year-long+ project I did on a previous generation of this site, intended to find and improve the accuracy level of three side-by-side-on-the-sales-rack M-N 91/30's. This involved shimming and handloading in the later stages.
It's hard to determine the OP's desires from a deleted post, but in reality, it's very likely to be an umpteenth rendition of the slew of such request which prompted my project. Thin skin or thick, my responses would be the same.
Most 91/30's were mass prepared and stored sometime after WWII. Most of them suffered from serious cleaning rod wear in the muzzle area, and the generic mass-fix was to counterbore the muzzle down to a distance that reduced the bore diameter to a reasonable size. This was a very fast and uncritical process. The end of many/most bores was a crapshoot, complicated by upwards of 50-80 years of general neglect in long term storage; cosmoline can only protect so much, for so long. Expect
much corrosion where a 'recessed crown' should be.
Then there's the ammunition. The steel case/steel jacketed USSR/GI spam can ammo was purely 'cannon fodder'. It goes bang, mostly. Aside from applications like massed musketry, it was probably always substandard; and age has not improved its performance.
If you have a 91/30 that shoots 1 MOA with
any ammunition, don't let it out of your sight.
Are there accurate ones? Oh yes. They tend to be battlefield pickups from the Russo-Finnish "Winter War" that were carefully researched and very dutifully rebarreled, restocked, and refurbished as Finnish factory arsenal (later to become SAKO) M-39 Rifles. Finnish ammunition is also special (7.62x
53). The bores and bullets are often described as .308 diameter, which is even sometimes true.
There are also some original 91/30's that defy the odds and refuse to suck.
For general purposes, a cosmoline excavated 91/30 and Spam Can military steel case ball ammo will probably deliver accuracy in the 2-5 MOA range, or worse. As a perimeter defense rifle, it's moderately satisfactory out to 100yd.
Oh, and they tend to kick like mules. If you get into the 180gr loads, you need serious recoil protection for extended target practice (i.e. more than ten shots).
In my unrelenting effort to develop a handload, I came up with PPU Brass, Win LRP, Hornady 150gr Interlock "303" caliber bullet, and 48.1gr of IMR-4064 (identical-charge to my Garand load). It's better than the steel case, somewhat; over the past ten years or so, it has harvested several dozen whitetails for my (now former) S-I-L. PPU 150gr Factory SP loads are a reasonably fair compromise.
People have
actually tried to blow these rifles up and had real trouble getting anywhere near their goals. Seriously, this thread
reeeeally needs a little bit of comic relief...
Mine is a safe queen (Archangel Stock, Bushnell Handgun Scope, Scout Mount, Limbsaver, etc.) these days. I shudder to raise it and fire it.
