A couple years ago Mustapha Curtis wrote me a few letters and told me about making a Rollingblock I believe in 444 Marlin with a faster twist barrel so he could shoot heavier slugs for things like the “Quigley Match” in Forsyth .
And now I'm considering doing the same thing . Well build the rifle that is , but just shoot at 100 and 200 yards .
Anyway for the “Rollingblock Experts” here . Is a typical in decent shape Remington 1871 rollingblock going to be strong enough to handle smokeless loads I would shoot in my 444 Marlin leverguns ?
