Ok guys a have a factory savage 220 swift that I have had for several years want to get going with a 52g hpbt sierra matchkings. Will the barrel stability that bullet and will reloaded 15 be good powder thanks.
 
RL15 is my go to powder also. But in my .22-250 Ackley Improved. 38.5 grains and 60 grain Bergers.

It had a 26” barrel at first and was running about 3800fps, then I cut 4” off when I got a suppressor now with a 22” barrel I am getting 3650fps. Best powder I’ve tried.
 
My go to powder for my 220 Swift using Sierra 55g HPBT bullets in IMR 4064. I use RL15 for my 375 H&H, clear on the other end of the scale, but have never considered it in my Swift.

RL-15 will work perfect for your swift. Its my alternative powder when I was out of 4064.
Only problem is as of now you cant get anymore of it. 1-14 and faster will stabilize a 52 gr bullet.
