30 SM with the 245 EOL

[bdyal1972]

Yes, you can fire factory prc factory ammo very accurately.
The longer barrels will help, to a point.
We need to test more with the 245's to find accuracy nodes but with a 30", I would not be at all surprised to find accuracy at 3000'.
A 9 twist will work well. Some folks are building 8 twist for very long bullets.
You can purchase Reamers, dies, and head stamped brass from my website at:

Any action that you could build a WM on would be fine.
With the 245's, you will need a minimum 3.8"
magazine. 3.9-4" " would be better.
Taper depends on what you're trying to accomplish but it sounds like you're looking for mostly long range target use? If thats the case, a Sendero contour would be minimum, and heavier, as much as you wanted.
If Its long range hunting, I would go minimum #5, or 3b in a Bartlein.
I like 4 groove Krieger barrels, 5r Bartlein, Brux, Rock Creek, etc. Lots of good barrel choices!

Rich ,

Do you have a photo of loaded cartridges of 30 SM standing next to .300 PRC that you could post ?
If a factory .300 PRC will fit into , and shoot from a Sherman 30 SM , is the brass then fire-forming into the 30 SM case dimensions ? Or is there some other case design difference ?

Thank You ,

and here:

300 PRC SHERMAN IMPROVED

That's correct! The 300 Sherman PRC S.I. (now officially the 30 SHERMAN MAGNUM) will have reamers available by 1/1/19. Most of you have likely heard about the performance gains in the Sherman cartridges. The 300 PRC S.I. is no exception and has some really cool added appeal! The S.I. version...

You're killing me Rich. I'm going to have to break down and build one of these.

Yes, you can shoot Factory 300 ammo and then reload with Sherman dies

You guys might get me divorced yet. I like several of these Sherman rounds and this thread has me thinking about rebarreling my 300 Winnie.

 

[bsnyder]

Why why why I have to finish the two Sherman's I have before I start a third I just keep telling the wife these rifles are for her and I. This is really tempting but I have a gap in the 338 world so may look at a 338 Sherman but Dang that's impressive

 

[rockwallraider]

may have settled on a load, this is my 82 grain ( 2950 ) at 200 yds as I was playing with seating depth. Gonna shoot these out to 500 yds and see how they look but think I may call it good

Looking pretty good for 2950' on a 26" barrel. Not too surprising because 83-84 shot well with a 230 in mine.

 

[bsnyder]

what app is that? I have been trying to find that? disregard i think i found it.

 

[Westernhuntr]

Does anyone have the case capacity of the 30 Sherman with fire formed ADG brass?
I'm really looking forward to putting mine together.
