My 338 Sherman Shortmag

I can't keep track! I know there are 6.5's and more interest. Someone up there needs to stock Sherman stuff.
I agree we need a Canadian guy to stock stuff. I think if there was there would definitely be more of us up here.
You should talk to Clay at Prophet River he may be a good one to use as a stocking dealer.

Agreed, that would help for sure. If you get someone up here that commits to building a 338SS, and is concerned about brass to get them started, let me know and I'll donate some RP stamped to them that I have already prepped. It's ready for fireforming, already pushed the shoulder back, necked up, outside neck turned, trimmed to length and chamfered. At least it would be good for breaking in their barrel and mild loads.
 
Rich, Can I use my already fireformed 6.5SS brass for the 338SS? Neck up & trim if needed? Or would that not be advisable. All the Smith work is completed, now for ceracoating. Hopefully two weeks for completion. 8# of Varget should get me going!

Yes you can. You may need to trim to length since the taper and shoulder are already formed. After you neck them up, check the oal and trim to 1.930" if necessary. Your chamber is 1.940"
 
Guys,

Love this thread. I have a 338 SS being spun up by Clayton Smith at West Texas Ordnance. Will be on a Bighorn Origin action and 22" Bartlein 1:10" twist rem varmint contour barrel switchlug rifle.

I have plenty of Varget and 213g Hammers, 225 Barnes and some other bullets to test.
 
338 SS Ammo.jpg 338 Sherman Short mag.jpg 338 Sherman 200y.jpg Here is some .338 Sherman Short Mag custom ammo that just got finished up to send out to it's home. These are loaded with a new 235g Hammer Hunter at 2840fps from a 24" Proof CF barre. This rifle did not like the 222g version as well. We were able to get the vel higher but was tough on brass and accuracy fell off. In the end we decided that the extra 50fps from the lighter bullet was not worth it. The cartridge seemed to work better with the heavier bullet. May just be this rifle, but efficiency definitely got better when we stepped up the bullet weight. The target pic is at 200y.

I am still amazed that we got this kind of performance from a cartridge only running 66g of Varget. Thanks again Rich!
