Smokeless Muzzleloader Build

[mwwoodman]

What would work best with a .40 caliber barrel? Saboted bullets or full bore?

Definitely no sabots. I do them with a cut rifled 1-15 twist.

This is my method of headspacing bolt muzzleloaders without using a nut system. You can keep the shank at 1.25" diameter. A fixed length module plug is used which has a short carbide bushing in the rear.
We do this on Paramount conversions and Rem 700/Defiance Outcast and clones. There is a concealed shim ring which we make in a handful of size increments, seen in red. Nominal ring thickness is 1mm (.039) so it gives quite a bit of room in and out. We make .003, .004, .005, .031 and .039 rings which give plenty of flexibility to set head space and time fluting with zero gunsmithing or custom machining required.

Would that work with my small shank savage 7mm-08 donor?

What is the barrel thread on that? What is the receiver diameter?

Are you making/selling prefit barrels? I have a Howa 1500 in need of a .40 sml barrel.

Thanks

I’m traveling now. I’ll check the receiver diameter when I get back home next week.

My Savage Axis II XP has the small shank. Strictly from what I have read online the small shank threads are 1-1/16" x 20 TPI. https://patriotvalleyarms.com/barrel-nut-for-savage-remage-barrels/

Only prefit for ones listed, Paramount and Rem 700/clones.
