The NULA is also a great BH209/Black Powder subs ML as well. Very light weight and accurate.

Congrats on the good shooting.

So, how is his breach plug made? Is it the henry ball design? does it have a vent liner?

How would you compare it to the savage design? Longer, more threads?

Actually i had planned on trying some BH209 with loads that normally blow sabots with smokeless. I will PM you later about some load info if thats ok.

Well pics are easier but i will say IMO the plug and bolt design is better because it fully supports a CCI209M primer. The plug design is much different and actually seals the primer against a 4340? ordnance steel bolt. The bolt also has a small recess so the primer rim cant swell and cause separation. Tolerances are extremely tight and the firing pin is a bit smaller also. They don't nearly as stressed as primers ive shot in any other gun even with a max load.





When compressed the bolt actually pushes the primer rim against the edge of the BP too and creates a secondary seal besides just a typical crush fit. The is no liner and the plugs are supposed to last over 10K shots.

Sounds good
