I have a Chasspot/Gras carbine with a ringed barrel approximately 1-1/4” in front of the rear sight. You can feel it on the outside barely and can see, what looks like a gap inside, a black ring on the inside. When running a tight patch you can feel the loss of the rifling then catch it again.
The question I have is it safe to shoot with BP 3/4 loads. With the rifling almost the full length, I’m not worried about accuracy just don’t want to have a kaboom over my hand. It is a 1873 with a sleeved chamber if this helps any.
Thanks, Rob.
PS- where can I buy 50-110 WCF brass at ?
