Welp after having this thing for......5- 6yrs now finally staring loading for it. She's been bubba's not the best bore , ect so decided I want to make it into just a good ole practical minded rifle. Nothing fancy past the strap on check piece. Will say though who ever had it last did make the trigger kinda nice


Anyhow got this mold from NOE 316-213-RN HP. Sized it down to .314 to begin with ( bore slugged at .313) gas checked powder coated instead of traditional lube. .315x.311 neck expansion IMR 4227 power .
Probably would have really helped if I was
1 not shooting off the tripod which I suck at and 2 if I don't wait till I could barley see the target...plus the rain ... But hay I was excited ..and there was a random calf walking around my back stop so had to take care of that guy anyhow hopefully itll be better tomorrow and I can get on the ground on my bipod or rest .... Still better then what I've had other people tell me about their experiences with cast in Mosin's. Not being able to say on paper at 25 , shot gun patterns , key holeing and all that goodness.

Looks like a great start. What's your velocity target?

What distance?

Have any slower powder like Varget or 4895? U might be surprised

Blue bullets to shoot blue helmets... lol

curios what your target velocity is

I know a lot of the cast shooters would run a load of 2400 they were targeting about 1400fps it was a fund to shoot cast bullet load and not a full power by any means

I know someone has the 2400 loads posted on castboolits I recall reading it but it was several years ago
generally a faster powder and moderate velocity was their go too

I didn't have any 2400 I went with the Unique type recipie slower yet but man you could shoot all day

I think I was running 6 1/2 or 7 gr power pistol (what I had for powder that was during one of the shortages)under 170gr cast and lubed in 30-30

I could sit and ring steel at 100yards with that load not gas checked , it was a gas check mold I didn't have a chrono then so I don't know what they were going for speed
it was a pleasure to shoot almost nothing for recoil

Way over my head but interesting

Showing your mistakes and failures is the best way to learn imo. For every 19 or so people who wanna say something smart or make fun of you there one or two people who are more then willing to help and their the ones to make showing mistakes more then worth it.
Shoots 2' all day at 100yd with factory Soft points. Honestly people can make fun of me and my projects they want if it helps them sleep at night and makes em feel all warm and fuzzy but I generally don't care much unless they have some actual advice lol.

Whatever is accurate lol. Honestly don't want anything over 2000fps just because, why ?

I would go the other direction start low and work up

ahhh I found the post or one of them I remember reading
Larry Gibson did a lot of testing he found that it wasn't so much a velocity threshold but an RPM threshold with cast

a search looks like Mossin Nagant is a 1 in 9.5 so you probably want velocity around 1600fps would ne my thinking

I have 2 of the Mosin's. Both earlier models.

One is the long type with a scout scope on it.

The other one is a carbine sized with a regular mounted scoop.

Neither shoot very well. I use military ammo. I have soft points 178 grain, for deer season.

Little update in the Mosin and The NOE 316-213-RN HP.
First group of the day right at 2" @50yd . Not too loud very nice light recoil
Cased up a bunch more with a harder alloy. Checked this morning and after casting water dropping PC and water dropping again they where around 15bhn if I remember right. Sized and gas checked too .314 ( bore slugged at .313 would have went to .315 but I forgot it order a .315 sizer bushings and since I'm only home for a short amount of time I just said I'll work with this till next month ) powder coated then sized again to make sure it's still a good .314. Expanded my necks with my NOE .315 x .311 expander plug. No crimp

that is a huge improvement over the other night

maybe next month .315

Much better. Where you get the brass? I too have a long and short version. The scout has the bayonet on it and the long I put into a Boyd stock. No scope on either of them.

Bought 200rd of PPU soft point a few years back and I've just been working though that. Shoots them ok, 2" @100yd all day but kicks like a mule...or at least a really irate Shetland will say though I need to see if I can get someone to make a copy of this mount but steel and picatinny instead weaver

Yes sir , slowly but surely

Definitely will be going up in sizing gotta get some for the 8mm next so that all will probably be on the same order lol
