Gunsmithing barrel too big to hang without block?

[toddconley]

I just ordered a a-5 for a sako l61 barreled action I have laying around. It has a 29 in 1.45 barrel on it. It is 7mm-300 weatherby. Will the action support this barrel at this length? Should I bed the barrel? It came out of a bedding block but the rifle was just usable and not fun at all.

1.450" straight on a Remington 700, you might want a barrel block on that pig. Thats a lot of weight.

l61 sako. Could I full length bed it?

Re: barrel too big to hang without block?

I would have that barrel contured to a lighter profile, there is no need for a barrel that thick.

Re: barrel too big to hang without block?

If you do want to use it you would want to bed some of the chamber area and maybe even at the end of the stock. Or like roscoe said a block would be the best way.

That's up to you.

That describes some of the Heavy BR guns at Iowa last week, and I suspect that was it's original intended purpose....

Re: barrel too big to hang without block?

That was its intended use as a big br gun but I already have one this big and this one is just no fun to shoot. I hardly ever shoot it. The stock it came out of is junk but, it will shoot like a house a fire. I want to run some big 284 bullets from this thing and shoot stuff a long long was away. Could I full length bed it? What would happen as the barrel heated up? I bet the A-5 would flex before the barrel did? What about the action bolts? Would the torque of the action screws put adverse binding torque on the action if the barrel was bedded all the way to the end? How would you determin that part?

Todd you need to clean out your pm box. Tried to send you one but would go.

The forces caused by gravity/weight pale in comparison to the stresses incurred during firing....

Little slow, dont get it? Elaborate

 

[WRM]

Re: barrel too big to hang without block?

Chamber pressure during firing causes much higher stresses in the action/barrel threads than the stresses caused by the weight of the barrel.

If you bolted it to a solid bench and applied load at the muzzle until something failed/bent (action screws, barrel/action or threads), it would be "an order of magnitude" load as compared to the barrel weight.

Let's try it?...

Re: barrel too big to hang without block?

So you think bed the action up and free float the barrel just like I would normally and see what happens. Then if it dont shoot then do something different? This is knd of what I had planned. I know the gun will shoot, so if it dont shoot when I restock it I will know something is up.
Thanks,

Re: barrel too big to hang without block?

I think it would be "strong enough" to hang that big tube out there, but personally, I'd probably go ahead and bed the first several inches, just for support and "help out" that stock....

I "free float" a 1.25 X 32" 338LM tube off a Barnard; gunsmith didn't give it a second thought.

Re: barrel too big to hang without block?

What about the torque imparted on the action vs. barrel by tightning the bolts

 

[Rhys]

Re: barrel too big to hang without block?

I'd bed the first 2 inches or so of the barrel just to support that joint a bit.

 

[WRM]

Re: barrel too big to hang without block?

Not sure what you mean - the action screws would be practically under the same stress as a light (or no) barrel similarly torqued, provided bedding does not interfere and put the action in a bind?

Cheers,

Bill

 

[toddconley]

Re: barrel too big to hang without block?

I guess that would be true. I think I will bed the action and the barrel mabe 6 or 8 in and see what happens. McMillian say 6-8 weeks before I get it anyway.

 

[WRM]

Re: barrel too big to hang without block?

It's going to have quite the barrel channel!...

That barrel is probably "chamfered" at the action; I'd relieve/mask the bedding so that doesn't act as a second "recoil lug".

I was thinking 6", but 8" wouldn't hurt anything - that barrel isn't going to flex much. May want to look at it from the other "direction" - bed to 8" from the tip of fore end to keep it stiff, for example? Barrel supporting stock, rather than vice-versa....

Cheers,

Bill

 

[toddconley]

Re: barrel too big to hang without block?

Do you mean bed from the tip and skip the middle and bed the action?

 

[WRM]

Re: barrel too big to hang without block?

Hi Todd,

No, was talking about "measuring back" from the tip to figure where to stop; but still bedding from action forward as in conventional bedding....

I'm just thinking about this differently - instead of the stock as the foundation/structure, you're putting a stock around a barrel?...

Cheers,

Bill
