I have a Big ole Donnyfl on my .457 Texan carbine and love it. A little long but works great. I recently got .357 Texan carbine and just received the adapter. The Donnyfl will fit both guns. I won't have a chance to shoot it for a while(until deer season is over) Do you think the bigger .457 will stop the sound good enough or am I looking at buying a new one in .357 in the near future? Thanks. Hopefully someone has done something similar with a big bore.
