Rifle vs Shotgun action strengths

[tinker2584]

Does anyone know what if any difference there is between the sb1 and the sb2 recievers,other than  the fact NEF will not rebarrell the shotgun to a rifle chambering.
Thanks
Frank

Frank It is the Heat treatment of SB 2. Makes them stronger,
I would NOT put a rifle barrel on A SB 1. esp, 30-06 280 270
 308 243 25-06 Maybe pistol calibers and Hornet , 30-30.
 Marv,

Tinker, Marv is right as usual.

To explain a little more, the current SB-1 is at least as strong as as the older 158/Topper action was. The Topper was made in .22 Hornet, .223, .30-30, .357 Mag, .44 Mag, .45-70, and a few more, so those calibers will be OK on a shotgun frame. All of the .308 and .30-06 case based cartridges are too much.

It all comes down to the difference between cast iron(sb-1) and tempered steel(sb-2). DJ is correct about the cals to shoot and not shoot. I have fired both my 30-30 and .223 from my shotgun receiver but would not try my 25-06. Paul5338(?) is shooting a 357 from a 12ga. receiver I believe.

lik2hunt,

That's correct.  It's a late model Pardner (SB-1) receiver and I have shot .360 DW's in it too.   I used to shoot it on a H&R "AU" shotgun receiver.

The .45/70 barrel I have coming in will go on a shotgun receiver also (the "AU" receiver).

However, DJ and all are certainly correct about the .30-06 category chamberings being too much for the shotgun receiver.  I have 2 SB-2 receivers for that purpose, but the highest intensity/pressure chambering I have is .223 Rem.

Gentleman,Thanks for your replies.I'mm getting a 410 NEF but I also have 44 barrell here that I would like to chamber to 444Marlin and link to the NEF reciever. You have been a big help.

lik2hunt, what is a .360 DW?

tinker2584, In case lik2hunt misses the question the .360 DW (Dan Wesson) is a lengthend .357 Magnum, but shorter than a .357 Maximum. The shell lengths would be .38 Special, .357 Magnum, .360 Dan Wesson, .357 Maximum....<><.... :grin:

[marv]

Frank a 360 is a out growth from 357 Mag. used in some Dan Wesson revolers. the case is about mid way between 357 Mag and 357 Maxmum.
357 Mag case is about  1.31 inch lenth 360DW lenth 1.41in
357 Maxmum 1.61 in . Some of the NEF 357 Mag rifle have a long  chamber and people able to shoot 360DW in them , getting bullet closer to the lands and groves. My NEF had a chamber lenth of 1.42"
I used a reamer cut it to 357 Maxmum . works real great. Marv.
 PS hope explains it to you.

I think the question about the DW's has been answered....good thing cause I am only slightly familiar with that round. Don't have the .357 now but plan on getting one sometime next year after the new barrels are manufactured. (I'm so happy!) and I think I will try some of the DW's in her to see about getting just a little more out of it than the standard round. Hopefully some of my friends here will be able to help me out with some good load data by then. Ya'll keep working on 'em!

So they're adding the 357 back to the barrel program?  What about the 44mag?  I heard they discontinued that one also.

Ian, last winter when they were using up the last of the discontinued 357 barrels, they ran out of 44 barrels for a while. I haven't heard anything else, but that doesn't mean they didn't drop the 44 without me knowing about it.

[lik2hunt]

Haywire - I don't think they discontinued the 44. If I'm not mistaken a large shipment of assorted rifles has gone out to suppliers recently due to the fact that season is quickly approaching. I bet if you check some of the major suppliers such as sportssouth for instance you'll find some in stock there. The .357 will be produced again toward the end of this year according to a post here recently. That's all I have to go on - haven't called and asked CS myself.

It all comes down to the difference between cast iron(sb-1) and tempered steel(sb-2). DJ is correct about the cals to shoot and not shoot. I have fired both my 30-30 and .223 from my shotgun receiver but would not try my 25-06. Paul5338(?) is shooting a 357 from a 12ga. receiver I believe.

Lik2hunt, the cast (mallable) iron frames are the older H&R frames. It's my understanding that SB-1 and SB-2 frames are all investment cast steel, identical except that SB-2 s have been heat treated. Even the SB-1s are a bit stronger than the earlier frames simply because they are made of a stronger material. I would not attempt to use that extra strength, but it's comforting to have it as a safety factor.

I think they are both the same cast steel.
No one makes guns from cast iron.
