If you have the 62 TSX perking, no need to try anything else....
Weren't no issue to make them perk.
But I am a bit biased, being I've seen little in the Nozzy .224 "60 something" grain bullets not bested by other makers. They always perform on the structural/performance level, but accuracy always seems to be an afterthought.
I agree with that comment concerning the 60gr Partition, but I've found the 64BSB's to shoot bug holes in both rifles I've tried....and one of those is a Kimber!
The 64's are pretty tough bullets. I sectioned some earlier and posted pics in this thread. I'm a BIG fan of the 62TSX, but I don't see them doing anything more than the 64's will do.
I'll know more in a few months...
I enjoy handguns and I really like shotguns,...but I love rifles!
