I do like to use 22 short ammo when I dispatch fur in the trap...Way back when I have had rifles designated as S, L, LR acceptable... I have a NEF 22 LR double action pistol and it's designated 22 LR. Also a Single Six. But can't recall if the Single Six is designated as 22 LR only. There have been times when I wanted to shoot a pest animal with the CCI 22 Short CB... Would you use the rifle designated as S, L, LR for the 22 short CB's or do you think you could actually shoot one with the NEF designated 22 LR hand gun?
Figure when gun MFG. designate a 22 RF as LR one should not be shooting Short ammo down it's barrel! Maybe?
What is your opinion on this? i' m sure the semiautomatic need the extra power of the LR ammo to eject the fired case from the chamber..
