I have a Extreme 50 and shoot BH with the FPJ and it works fine. While I was I hunting I would NOT use a used jacket - use a new one. My BP is the concave models. I think the convex model has to small af a flash hole.
Either one of these will work. I have only used the Non-FPJ plug with BH209, love it.
The N-FPJ conversion actually sits in the FPJ slot in the bolt and is an extension of the bolt. I allows you to drop in a primer and chamber it in the plug. It also extracts the primer, turn gun to the right and primer drops out.
Thanks. the n-fpj looks cool but does it work for hunting. I have had my bolt come open when carrying by the sling, and lost my primer. Will I have the same problem with th n-fpj. With it keep my prime dry.
IMO the FPJ is so much trouble to use, it would be worth the money and effort to switch to the non-FPJ + it's one thing less that you don't have to keep buying form the manuf.
