91/30 rifles hunting in 2015

[Clark]

My friend used a 180 gr Sierra in a stock 91/30 barrel.
He shot an antelope buck.

I used a 125 gr Nos Bal Tip in a Krieger 300WinMag barrel on my 91/30.
I shot a mule deer buck.

I killed my first deer with a lightly modified 91/30 and will try to get another this year.

[leebuilder]

I will use my sporterized mosin this year.
Nice shootin Clark!!!
Be well

[LIMPINGJ]

Clark who made the replacement stocks on the rifles?

[Clark]

I got the stock, unused but old, off ebay. There is no name on it.
Probably Fajen, no longer made.

[RugerFan]

Very nice! Hadn't heard of anyone turning a 91/30 into a .300 Win mag.

[Clark]

I converted a Mosin to 45/70 12 years ago.
Then a 30-30
Then a 7mmRemMag
Then a 223
This year it was a 300 Win Mag.
This is the first one that killed anything.

The Krieger barrel on the 300WM is very high quality, but the Rem700 222 take off bull barrel on the 223 gets the smallest groups.

To get 3.34" long unfired ammo to unload, I drill a hole and put in an ejector over ride button:

I was kicking around the idea of a 300 mag one after those finnish 300 mag sniper rifles surfaced but settled on a 300 wsm heavy barrel

how did you make the 223 bolt head? how much did you have to modify the magwell to feed them

[Clark]

The 223 is single shot manual lifter center bottom ejection port.

I milled out the extractor groove in the bolt head and bent the extractor closer to the center.

[Clark]

The 223 case has a thinner web and requires more support

[pacomdiver]

I have an orphan mosin action, a lot of sporterized takeoff parts including stocks and a couple spare barrels including a brand new 20" rem700 tactical barrel so a 223 might be my next build

what twist is your 223 barrel? what weight bullets was that group shot with?


just dug thru my spare barrels, I have the 20" Remington 700 varmint 1-12 223 tactical barrel and a 20" 223 1-8 unprofiled blank. a brand new rem 700 varmint 1-12 22-250 and a ruger m77 varmint 243 barrel


decisions, decisions

[LAGS]

I was never comfortable with taking a MN out to pressures over 45 to 47,000 CUP
I saw a MN converted to 30-06 blow up after the guy had it for ten years.
It was factory ammo also.
But Hay, if it works, then do it.

Clark,

Tell us about your 45-70 conversion if you will. I'm very interested in doing one.

[pacomdiver]

lags, was that mosin 06 a bannerman conversion? some of them were done substandard and couldn't handle factory loadings because they set the barrel back and reamed the new chamber instead of replacing the barrel

[leebuilder]

Amazing work Clark.

[82ndMedic]

Nice shootin! I'm trying out my yugo Mauser this year for the sport of it :)

[LAGS]

The MN that was in 30-06 was not the original barrel.
I would not shoot one of those Bannerman conversions because they are too unsafe.
But in rifles that old, I am sure Fatigue can set in over time on any rifle.
So I prefer to keep them within the original Design Pressure Range to be safe.

For the 45/70 I ground a tool to open the bolt head face in the lathe.
I could not fit the barrel in the rotary table to cut the 170 degrees of extractor relief, so just put it horizontally in the mill vice, made a small cut, losened the vise, rotatated the barrel slightly, made a small cut, repeat.

1) I used the 45/70 as a single shot.
2) The 30-30 as a single shot.
3) The 223 as a single shot with manual lifter and bottom eject
4) The 7mmRemMag is a repeater with ejector over ride button emptying unfired ammo.
5) The 300WinMag is a repeater with ejector over ride button for emptying unfired ammo.
6) The VZ59 machine gun barrel, i found one of 12 receivers that would clock with arbitrary Tennessee Guns extractor relief cut. I drilled and tapped and filled the gas hole. I made a steel cover for some of the barrel features and loc-tited it in place
7) A Mosin with pitted chamber, I recut the chamber, moved the shoulder, and re cut the extractor relief cut.

Killed my first deer with a stock N.E.W. Mosin 91. Speer 150gr Hot-Cor over 54gr IMR 4350 in 2007.

decisions, decisions

The ammo is 35 gr Vmax moly, 15 gr Blue Dot 2.17" OAL, 35kpsi 3500 fps,
custom reamer with throat is 0.050" short and the neck is 0.250".
That is 14" twist barrel.
I have built 16" twist 223s and so has my brother that shoot that ammo well.
It is the ammo I have used to kill thousands of ground squirrels and dozens of prairie dogs.

Nice Work !
