The 25 conversion works great for my wife's NEF. My Omega shot very well and clean without it. As for the bullets, my Knight Disc XT flat out loves the x-tended range 180's (45 cal) and my Omega shot the 250 Dead Centers very well. 2 deer with the DC 250's at ARO 100 yds, 1 bang/flop, the other took about 3 steps and wobbled over. Could not get it to shoot the 40/50's at all tho. Had mixed results with the double duplexes. Don't like mixed results while hunting. Don't shoot the Vari-flame adapters! Sometimes they go bang, sometimes they go pop! If you really feel you must try them, PM me for some!
Alos, I like their RAT jag too!
