I have had good success with Nosler Ballistic Tips and Sierra MK' s. The Hornady' s are dissappointing in my 22 cals. I shot theses groups about 2 weeks ago, they are a good representation of the .224 50 gr. Nosler Ballistic Tip in my 28 " barrled 220 Swift. It' s steady shooter in the .3' s with 5 shots @ 100yds. These were loaded with enough IMR-4064 to push em a tad over 4000fps. Not truly outstanding BR accuracy but good enough for the shooting I do.
The bottom line to me is that you have to experiment some to find out what combination your particular rifle likes, this would include bullets, powders/ weight, primers, O.A.L. etc.
Keep em in the black........AA
