Wise words from both of you gentlemen to which I vehemently agree.
I prefer the 147 grain based upon my experience but am open to the 115 and 124 grain bullets. If they all work in my Robar R9, what is not to like?
Concomitantly, if the 115 and 124 bullets did not work in my R9 and the 147 grain does, I echo what is referenced above; "whatever works for you".
