Tried the X's in a 257 Weatherby years back and groups would double or triple after about 6 rounds. Thorough cleaning and I'd be good for about another 6. Went to mollied Partitions and the issue went away although those are quite explosive on close in game. Not been near Banes since.
We’re these the original X’s, or the newer, grooved X’s? I feel the same way about Sierra’s, for use on game. But, I would send someone else to the gun store to buy them for my varmint rifle!
Maybe you could do the same.....find out that you’ve been cheating yourself! memtb
