[QUOTE=mod34;136984992]1) I've re-read the posts and don't see anything where others have indicated that they "really aren't made to use in more modern rifles".

2) Why in the world not??[/QUOTE

I have several newer bolt actions and semi-autos which state 22LR. Only my vintage models state S,L, LR. Thus the basis for my statement, I am not an expert just IMHO. Others on this forum are much more qualified and can judge for themselves.
Didn't mean to imply or put words in other posts that weren't there, Mod.
