338 federal
« on: December 14, 2009, 07:05:10 AM »
would there be a pressure problem with a handi if you had a barrel made up on a 20 ga stub in 338 fed.    will the sb2 frame handle the pressure?   looking for information before spending the money.   thinking of the 338 fed as a compromise of range and power between the 45-70 and the 270.  any and all information is welcome

338 Federal pressure are no higher than any other 30-06 class family, but to do it on a 20ga stub may not be the best idea, shotgun barrels are 1137 mild steel, centerfire rifle barrels are 4140 alloy, I have a 6.5x55 stub which I run over 60kpsi which is the same pressure as the 338Fed, but mine is on an SB2 rifle barrel stub, I'm sure our stub expert Larry will check in on this tho.  I think a better option would be to have another H&R barrel rechambered and rebored, or used as a donor stub, cost to have it done is about the same, $300 plus the donor parts. Site sponsor Wayne York has done a couple for me, is doing a 243Win to 260Rem for me right now, he also did my 6.5x55 Stub with a Shilen match blank.

Quick is right, problem I see is getting the chamber wall thickness you need while still fitting it inside the shotgun stub.  I don't think you can count on the stub wall thickness when deciding if the chamber area thickness is enough, and the 30-06 pressures are kind of high for trying a science experment.  Stick with the old lower pressure chamberings and things will be good.  Larry

I think a .243 would be a better donor for a rebore, if the outside diameter of the barrels were the same. At least I was told it is better to have more metal to remove than less when reboring.

A .243Win is sufficient for a .264" rebore, having a Superlight being done now, so a .308" would be fine to .338", but either would work, so would a 7mm-08.  ;)

Would 243,7-08,308 chambers clean up going to 338?
Maybe a 30-30 would leave more to work with.

The AmmoGuide rechambering guide says all three that I listed will work, the 338 has a bit longer shoulder so it would clean up all of them.  ;)

QUICK what do you thick of reboring a HB barrel a .223 or a 308  so you have the extra weight to help with the recoil of a 338 when it is done the handi 338 will be around 6 lbs? the 338 what about 22 lbs of recoil? some lead shot in the stock might be needed also?

A bull barrel 338 will weight more than 6lbs, a standard contour 22" 35 Whelen in syn stock weighs close to 7lbs. I wouldn't worry about the recoil of the 338 Federal, it's just a 308Win with a little bigger bullet, not much different that shooting an 30-06.  ;)
