I've barely had a dozen Swifts. Hint.
In an OEM 14" and for killing schit dead,I'd wanna drive the 50 V-Max at nearly 4000fps ala '15.
Hint.............
If you can get the 50's to shoot in it, that is the route I would go. I tried everything I could- 50's, 55's, Vmaxes, BT's, Sierrras, etc.... in my 700 22-250 and about to toss it in a river when I tried the 40 BT's and it shot them great. Even tried 40 Vmaxes and it wouldn't shoot them. Go figure.... In this arena Stick has shot about 100 times more than anyone else on this site so it is definitely worth buying a box and a lb of powder to try...
The secret I found with them is seating depth and getting close to the lands. If your throat is cut right you shouldn't have any problem...
