How much does it weigh?

 

[Alex Wheeler]

About 3.5 pounds. I asked them to make this action for heavy gun br and f open. Its an M with B ports and a shorter stroke.

 

[Ken Melgaard]

Alex, just wondering with the Bat MST and model B ports, (3” feed & 2.2” ejection) would this work with the WSM & SAUM cases?
Or would need a slightly longer ejection port?
Thank you
Ken

 

[Alex Wheeler]

Yes, the 2.2 port works. Just tell them its for a wsm when you order it

Ok...question from a NON GUNSMITH. What is the advantage of a flat bottom action?

Better for bedding

What stocks will fit this action, Alex? I assume Kelbly's but not positive.
Thanks, Dave

Looks like McMillan will inlet for this

I do like flats for bedding, even for glue ins the square shape gives more surface area. Its also the heaviest configuration that comes with an integral rail.

I do all of my own inlets. I have put these in LRB stocks and Kestros stocks no problem. They will fit any stock that will take an M. Im finishing up couple 300 saum imp heavy guns in LRBs with these. Ill put up some pictures when Im done.

Thanks Alex,
For your reply, it’s what l will look at building, Bat MST action Flat bottom with “B” ports in one of your solid fill LBR stock in 300/7mm SAUM Imp HG.
Alex, your thoughts on using 28” long 1.350” diameter barrels, with the action screw & glued into the the stock. I like the idea of the flat bottom action.
Thank you for your thoughts

 

[Alex Wheeler]

I measured the action flex with 30" 1.350" barrels on these actions. No problem.

If you envision closing the bolt handle on a round action, the action screws basically alone, stop the action from rotating. Most recoil lugs only make contact on their back, not the bottom or sides.

On a squarish flat bottomed action, the flat on the bottom, and flat sides of the action against the sides of the stock, inherently stop the action from rotating. You could close the bolt with no action screws being in place.

When action screws feel pressure cycles from multiple directions, they are more likely to loosen up.

How about a multiflat? I have 3 round BAT's and one "multiflat".

In terms of resisting rolling, it’s hard to beat a square, fitted well into half of another square, but a multi-flat comes close. Rolling effect is not just from the bolt opening and closing, but torque on firing as well.

There’s really nothing wrong with a round action, just to clarify, but you do get more steel on a given width, for strength and weight, with square than round.

Winchester always touted its square bottomed actions relative to the round competition’s.

Other than the Stiller being aluminum/ steel sleeved is the footprint close to a “Viper” drop port? Looks similar in design.

 

[Alex Wheeler]

It has no similarities with a viper.

 

[whatwind?]

closer.....

x ring SOD style stock with gracoil recoil reducing product

my first burst stain job......first application, will sand some and apply clear once rifle is complete with bedding, inletting, etc....went with yellow, dark brown, leather brown, red, ox blood, and black

 

[Alex Wheeler]

Stain looks good, Id like to see it after its finished. Definately something you dont see often.
