Does anyone have any experience with Beartooth's new 425 gr. bullet in a model 1886. I read in the introduction of the new bullet it was designed with Marlin's rifle in mind. I have tried Cast Performance's 440 gr. bullet but had difficulty in chambering it in my 1886 carbine. I wonder if I would have a chambering problem with the new 425 gr. bullet? Thanks for your input. Rob May God smile on you!
