The blow back discussion has brought out some interesting issues. First, as stated I've not encountered blow back that I'm aware of. Starting out in the 70's I shot mostly all side locks then flintlocks. As the 90's came around the in-lines came on the scene and I would guess this blow back thing came about. My Knight, with what little shooting I've done, hasn't shown any of it. The TC Triumph doesn't show it either. Whatever comes backward is wasted performance and should have went out the front so it's not a good thing. If I see it in the Traditions I'll report on it. I'd like to hear from others with different makes/models on what they see regarding blow back.
