SP01Shadow , that is a very generous offer and I may in fact take you up on that .
I'm not married to this particular bullet and have some 147 plated coming to just try . I'm sure that the throat issue may show up more with those so I'll let you know , I also have a new barrel coming for this one , and wondered about a finish reamer / chamber length ?
Also some new mag springs are on the way , the more I looked at this the more I thought it was simply bolt over base , or as you said slide speed faster than mags could present . I have been really playing with the light hammer springs . I have noticed it is not all that easy to shorten up ejection distance with heavier recoil springs as it is to slow things down with a heavier hammer spring .
On the 1911's I would go with a tight radius on the FPS to slow it down with the best results, don't see that as an option on these cz's especially with the b guns .
Is there a standard length that you throat these barrels or do you just go off of a pet load?
thank you ,
