Starting to kick around project ideas

[pre6422hornet]

I like the 9.3 as well Tom, I have looked at a few Ruger Africans in that caliber on Gbroker.

And like everyone else has said... it is a hammer by the books.

 

[nvbroncrider]

I built a 338-06AI on a Pre-64 it's impressive but limited by the short magazine but impressive.

Just to give you an idea of numbers. The 9.3x62 is kept pretty low in PSI's for older rifles, but I would be pretty comfortable running it up to 60K without issues..

Especially in Nosler brass...

http://shootersproshop.com/index.php?ro ... uct_id=283

It would be pretty slick and Nosler 250 AB is a pretty sleek bullet for shooting just about everything, then that 286 PT or Solid for when stuff just needs a little extra! :lol:

Please Scotty stop it hurts. I have an action in hand 11lbs of H414 on the way. I want "need" a M70 Mauser collection.

As an aside, Jake. I picked up my Model 70 chambered in 7X57 today. I won't have time to scope it until next week, but then I hope to get out and see what it can do.

I don't need more assistance from north of the border. I have Enabler East doing a fine job!!!

Tom, the 9.3mmx62 is a hammer and will serve well as an elk or moose rifle. However they are a little bit of a banger for recoil if you load them to modern pressures. I have a 9.3mmx74R which has the same ballistics as the 9.3x62. I enjoy mine and would certainly consider it a potent medium game rifle with 250 Accubonds at 2700+ fps.

There is always the option of a 8mm-06 as a straight conversion. It spices up 8mmx57 Mauser ballistics a fair amount.

Sweet, that is great news Mike! I have been seeing them all over GB lately, and man, the pull is strong on them..

Jake, yeah, the 9.3 would be a cool one and a good use to all of the 760/414 you have coming. Plus, Nosler has brass as 2nds right now. Might as well stock up now, you know if you wait, you'll just kick yourself later..

Thanks, Charlie.

I had figured that there was no free lunch. Shooting 250gr of bullet (or more) at 2400fps (or more) means there will be some recoil, for sure.

I guess I have to decide what I want at some point, but it's fun to kick the ideas around, for sure!

Depends on which way the wind blows...sometimes I really settle on the 338, others the 35 Whelen, and now the 9.3 is in the mix. Lucky for me, the rifle will have to live on as a 30-06 for some time yet (at least a couple of years) until I'm ready for the rebarrel to be done (from a financial standpoint). Lots of time to kick the ball around and hopefully settle on something that "grabs" me!

 

[DrMike]

I can't believe you are able to wait, Tom! :shock: There are some great options looming before you. As an aside, I shoot a 9.3X64, and I don't find the recoil objectionable. This is built on a Model 70 action with a Sporter stock. It does rock me when I shoot in the field, but not much more than my Whelen. This was built from a 30-06 donor, consequently. I truly enjoy this round, though I can't say it kills any deader than does my Whelen or any deader than game shot with my hunting partner's 338-06. All are great cartridges.

 

[tddeangelo]

DrMike,

There are several reasons for the wait...

(1) I still need magazine parts for the gun, as it is a detachable box mag m70, and has no internal mag box follower, spring, or floorplate. I have bottom metal, but need to locate the internals, which are surprisingly tricky to find, it seems.

(2) I have a custom flintlock project looming large on the horizon

(3) My wife and I are flat out of room in our house with 1 bathroom, the two of us, and three daughters. It's time to move, so move we shall, but that means discretionary funds for such projects are no longer "discretionary". lol

And there you go tossing another round in there...the 9.3x64....talk to me about that one?

Tom, I was concerned about recoil in two guns I've owned. First, my 300Wby, and second, the Rem673 in 350RemMag I picked up a couple of years ago. In both instances, recoil is stout from the bench, but nonexistent in the field, and accuracy has not suffered in the field, as can be evidenced by three shots this past season. With the 350Rem, a 60-70yd freehand shot on a jogging coyote dumped him in the dirt where he stood. With the 300Wby, a shot on a running buck dropped him at less than 40yds (probably about 20-25, really) without much trouble. Both shots were dead center boiler room shots taking out lungs and in one instance, part of the heart of the 'yote. The third shot was late in the day (4min of season left, even), with the 300Wby, at about 200yds, on a small doe. Hit her dead center of her shoulder/ribs, blew the lungs, and finished in the hip on the off side. In none of these instances did I even notice the recoil.

Additionally, both rifles have shown good accuracy at the range, despite the felt recoil. The 300 is able to pound out 1" groups with my final load, and that's a load I have not tweaked for seating depth yet. The 350Rem turned in sub-2MOA groups at 100yds with the sharkfin open sights, which I deem more than acceptable. I wouldn't worry much about recoil on the 9.3. It will be nothing compared to the 45-70, I suspect. One thing I've noticed is that while my 300 is a sharp kick, my 8x57 (180gr @2720fps) and 350Rem (220gr @2600fps) are both more of a push, without the sharpness and without the same jolt.

 

[DrMike]

I understand the need to prioritize. Housing seems to be a major need, even in the life of a rifle crank. Wives tend to become somewhat cranky when we buy or build rifles rather than providing for their creature comforts. By all means, keep Mama happy.

More punch than the 9.3X62, the 9.3X64 is a poor man's 375 H&H. It is easy to transform a 30-06 into a 9.3X64.

 

[tddeangelo]

Dangit, now the list is growing!!!!

 

[DrMike]

Ah, yes, the 9.3X64 is a delight to handle and to use.









Consequently, there are no flies on my 350 RM, either.

 

[tddeangelo]

Oh..my......

Drool worthy, that's the only way to describe that.

 

[DrMike]

And it will place three 250 grain AccuBonds into 0.5 inches, launching them at a velocity of 2700 fps. I do enjoy the rifle. It is comfortable to shoot, even from the bench.

 

[Oldtrader3]

DrMike, that 9.3x64 is a banger! BTW, I finally was able to buy some 250 gr AccuBond 9.3 bullets from Midway. I have them loaded for the 9.3x74R and ready to go to the range.

 

[DrMike]

It is a great cartridge, Charlie. I do like the 9.3X62 and the 9.3X74R. I guess I just enjoy the 9.3 calibre.

Can't wait to see the results Charlie. That 9.3x74 is a cool cat!

 

[taylorce1]

I'll have a 9mm or 9.3mm someday but I'm thinking a X57 just to be different. Plus anything I'll ever shoot with it won't know the difference between it and a X62 or 64! Right now I'm waiting for my buddies .400 Whelen to be finished to know if I have to have one or not, and the .375 Whelen is sitting there just calling my name but I own a .375 Ruger so it is hard to justify.

I understand about not changing the 1917 if that was your Dad's rifle. I wouldn't change that either. You could always do what I do, shop barrels and find the best deal you can on a caliber that fits into your range and whatever caliber you buy that's what you build.
