Can a small shank handle super mag caliber

[nuclabuyer]

Can a small shank barrel handle the more mag calibers. I think I asked this once but?? I am looking at building a 338-378 on a savage. If you google 338-378 savage, you will find a gun called a Wrath of God. Does anyone here have a reason that I cant use a small shank for this caliber..

thanks

A question posed on many an occasion.....so I did the math considering the UNF thread geometry. The last 3 columns provide effective sidewall 'meat' for the corresponding family of cartidges. Interesting to note that the Savage standard barrel thread root diameter is greater ;D than the larger diameter Rem/Wby barrel as a result of the finer (shallower) Savage thread pith;

Barrel dia" OD(mm) root '08/'-06 Mag WBY

Sav Std. 1.055 26.797 25.239 6.639 6.104 5.229
Sav wsm 1.125 28.575 27.017 7.528 6.993 6.118
Rem/WBY 1.0625 26.9875 25.040 6.540 6.005 5.130

You can read from this that theoretically a wby magnum in a STANDARD savage barrel leaves more steel around the cartridge (note this disregards action thickness) than a Weatherby MarkV in 378 family chambering.

you can probably do it, the bolt head needs to be opened up too. I build a lot of RUM barrels on small shanks though.

Might consider buying a NEW bolthead from Savage. Understand they are manufactured differently.

I would HIGHLY recommend getting the action trued/timed....or...at the very least, lapping the lugs until you are in the 95-100% contact of lugs to receiver.

I am thinking that I am going to be in the market for one of these. Currently I have a Sako M-995 with a PacNor 32" Palma that is 30-378, but I am worried about all the gunsmithing it will take when the throat is melted and gun. With a Savage I could have it shortened an inch and rechambered for way cheaper. And then reheadspace and go again. I am thinking 338-378, but the 338 ultra mag isnt giving up alot in ballistics and the brass is a little cheaper. I have been seeing all the 338 edge stuff on here, however I would either want to go all the way, 338-378 - 338 lapua or stay with a caliber that dosent need a bunch of work. In that case I would go with the 338 ultra mag.

Not sure which way to go yet.

The guys on here will beat you unless you make it a 338 EDGE. LOL. You could do worse though, in the size range you are looking at, it would make sense. Not to mention considerably less money that some of the hand cannons you mention.

[nuclabuyer]

I got on reloadersnest.com and was looking at the velocities of the 338 ultra vs the 338 edge and there is not a clear winner. I am sure the 338 edge is a little faster but I can not see it in the velocities posted. If you add in a 338-378, we increase the volocity by roughly 200 fps. This is where I am torn, 338 ultra is cheaper & easier while the 338-378 is faster and better. Not sure still

If you want 26 - 28" Barrel + brake... go RUM
If you want 30" Barrel + Brake, go EDGE !
If you want Horrible Barrel Life, Go .338-378

Love that picture Ace, I can never look at it without LOL.

Just curios, is this for an Africa or Alaska trip, or is it a case of "I just have to have one". Thats why I have a .35 Whelen, I just wanted one. But now that I have it it is one of my favorite deer rifles. Overkill for sure but bang flop is what I like. Have you thought of maybe a .338-.375 Ruger? Friend of mne uses a .375 Ruger in Africa and loves it.

In a 338 I would head towrads the RUM;
-Near standard Magnum Rim size will fit without mods.
-H&H Magnum OAL 91.44mm will fit Savage LA - 338LM possibly need mods to fit (93.5mm)
-brass standard size no forming (edge)
-few fps will probably not mean that much down range / recipient wont tell the difference...

I hunt elk and long range deer with a 30-378 and I thought it would be fun to have a 338-378 also. So I would class it as "I just want to" type of a rifle. But I have been more warmed up to the 338 ultra. For the same reason defoxer said. It is a lot easier, only problem is I dont have quiet the wow factor..

[sinman]

for edge brass you just run it through a fl sizer and your set, no more fireforming to that than an ultra. And with the edge you dont have to use only remington brass, nosler makes great brass for the edge too.

[efm77]

It probably can be done on a standard shank barrel. But if it were me, just to be on the safe side I would have my action opened up and re-threaded to the large shank size and then have a large shank barrel made for it to have a little extra meat around the chamber. The Weatherby shank may be smaller than the savage large shank but it is a shouldered barrel. For me the large shank is the way to go as it will handle the larger cartridges with a larger safety margin. But that's just my opinion.

[defoxer]

If you open up the ring and rethread you're just taking steel away from the ring and effectively transferring to the barrel to end up with the same overall thickness and amount of steel around the chamber. The ring and barrel will act in unison to provide strength. Large and small shank use the same diameter action as I understand therefore the overall thickness of barrel+action would be equal. The large shank barrel will however be more rigid and resistive to flex/vibration provided the contour is not turned down after the nut (the step). As a side note - a Mauser LR barrel at 1.1" 12tpi whitworth ends up with damn near exactly the same effective barrel diam as a SR Sav @1.055@20tpiUNF. Interesting.

[efm77]

You are corret defoxer. However, it's not true for the part of the chamber that is in front of the receiver ring which is what concerns me. Therefore, the large shank provides a greater margin of strength for that portion in front of the receiver. Like I said, it can be done on the small shank, I just wouldn't do it myself. Now if you're going with a conventional shouldered barrel then it really doesn't matter. But if you're using the barrel nut the large shank provides thicker chamber walls for that portion outside the receiver which makes me feel better. To each their own.

I have several Weatherby cases/calibers on my target actions. With barrel nuts (spanner)that are long and the O.D. the same as the actions 1.340 I feel completely within the safety limits.

I also have several Rum based offerings on both large and small shanks and have had zero problems. I can honestly say that unless you go to a longer barrel so you can use all of the powder in the Weatherby case, you will not beat the 338 Edge velocity using H4831 powder.

I love my Edge (handgun) and consider it the best thing I have ever done when I chambered it in my handguns. (3)

Good to see you back, Neil. How's the ticker doing?

[358Hammer]

Ticking! Doing very well Fred- Keeps going the way it is I will see you and your lovely wife at the Varmint Jamboree!

Edge for an Edge (if the actions are long enough) ;)

efm77, that's right about the chamber/barrel ahead of the ring, thats why I mentioned the 'step' ahead of the nut and avoiding it to maintain the strength and advantage of the LR. Honestly, if the WBY super mags hold together in a barrel/action combo that is smaller than the Sav SR (up to the front ring) then you will probably be safe with either Sav. The LR will allow a heavier contour from/thruough the nut. I will be screwing a 358STA barrel onto a 116; Down under the Sambar are a tad more receptive to a slightly bigger projie ;D....
I will need a mag base and frame to go from blind - DBM for both staggered & centrefeed LA whats the best/cheapest source?

Slightly OT, but good to hear the ticker going well 'hammer..
