Abilene,
I full well understand, YOU may full well had a very harmonious experience with YOUR rifles. I try to address issues based on having to
deliver several HUNDRED guns that will run a full match, Smokeless or BP, despite the owners best efforts to distain care and attention.
There are several Smokeless powders that will gum up just a bad if not worse than PB. Uberti chambers run the gamut from generous to
a manhole. Blow-by in straight wall cases, especially 45 Colt is a concern. The answer for competitors in CAS is not a compressed BP
round with a 250Gr bullet, or a heavy load of whatever smokeless and a 250Gr bullet. Besides, that recipe doesn't work in all cases (pun intended). Powder fouling is a concern and for that reason ......... EVERY....... maker of competition Short Stroke kits include Positive
Slam Down in the basic design of their Carrier Block Arm. EVERY maker. Why not add it to a stock throw rifle. It only makes good
sense.
I never had occasion to accept an original example with the screws loose. Obviously, folks lost the art of running around with loose screws. Original examples were in fact over sprung. It was done to compensate for early spring metallurgy and primers that took a
ruddy great whack to ignite. Where was I going. Oh yea, I remember ........
Don't be too quick to distain a modification that has proven to most beneficial to many, just because you feel you don't need it.
HEY SLIM
44-40, 38-40 and 32-20 run clean enough to take a licking and keep on ticking without much help. Straight wall cases on the other hand,
no so much. To gain any kind of "speed" advantage, at my age, I don't even think PEDs would help
