Proper cap for Treso nipples

[Smiling Bob Masterson]

Picked up a set of Treso nipples (model # 11-50-106) for my Pietta 61 Navy. CCI #10 caps that fit the factory Pietta nipples are way too tight on the new Treso nipples. Remington #11 caps are too loose. Have to do a road trip to pick up some Remington #10 caps to try. Is the inside measurement of the Remington #10 larger than the CCI #10 cap?
