Load for black bear w/ 314299 Mosin

[trail troll]

I am looking to get a solid 2000 fps out of my 91/30 with a 314299. Black bear medicine. I have been going with 16-18 grains of 2400 for paper, and tried a 29ish load of 4227 once. I have 4064, and the above powders. any ideas?

Hey thanks

Slower burning powders.

Try AA4350, H4831SC, RL19 or possibly RL22.

Since you have the 4064 try that. I'm using it behind condom bullets but haven't got that far with cast in my O3A3.

What kind of loads for a 314299 using ww760 or H4350 are you guys looking at? I have a M91 (32" barrel) to use them in.

[webfoot10]

Use 33 grains of 4350 under the 314299 boolet. If your 91 is Russian size to .313 and gascheck. If your 91 has a finn barrel
size to .310 dia. Should be pretty accurate out of that long barrel.

That sound awful light for a slow powder like that. I would expect to see something over 40gr. Listed maximum for XMR5744 is 32.5gr, and that's a little faster than IMR4198.

My M91 groove diameter measures 0.313 at the muzzle, 0.314 near the chamber. I'm using boolets from an NOE 316299 sized to 0.315 with a Hornady gas check and White Label Lube, over XMR 5744. It shoots better than the milsurp ammo, at about 1800fps. My Lyman manual lists 20gr (1513 fps)to 32.5 gr (2153 fps)of powder for this combination.
As for the boolit diameter, it's a snug but not tight fit in the neck of a fired case. It would probably cause problems if the bullet were any larger. I highly recommend NOE moulds to everyone if mine is typical. I cast a huge number with almost no rejects in an afternoon. They shoot better than most of the "condom" bullets I've tried.

How well did the "29ish load of 4227" work? That might get close to the 2000fps you are looking for.

Reducing powder charges for some of those listed can get to be a bit tricky...hang-fires, pressure spikes, etc. It may be good advice to stay with those powders that have a history of working safely with reduced loads, 5744, for example.
The online Hodgdon manual calls for a powder charge of H-4895 for the 7.62 with a 200 grain Speer SP of between 39.0 [2271fps] to 42.2 grains [2411fps]. The minimum load may push that boolit a little faster than the chrono results from Hodgdon with the jacketed slug.
The beauty of the H-4895 is that with data for ANY MAXIMUM POWDER CHARGE FOR ANY BULLET LISTED that powder charge may be safely reduced to as little as 60% of the maximum charge.
As example...the max listing is 42.2 grains. 42.2 x .60= 25.3grains. You may safely reduce the above listed powder charge from a maximum of 42.2 gr. to a minimum of 25.3 gr. WITH THE LISTED BULLET AND POWDER. As far as changing bullets, you are on your own. I do it all the time, but what I do and what you do are different things.

Lead Melter, I suspected there might be problems with a really reduced load of a relatively slow propellant. I seem to get the best results using the faster rifle propellants with boolits in rifle cartridges. XMR5744 has become my favorite for my really veteran M91 and the 316299.

I have used H4895 with good results so far. I have not crony'd them yet. I'm at the low end near minimum charge.
I'm looking for light loads.
I have also been fooling around with IMR trailboss. Its easy to use. I was only useing starting loads so far so no crony data. I personally would like to know if the Max charge of trailboss will push the 54r up to the 2000 fps mark.
Will be a long time before I get to testing though.
