28 Nosler and 30 Nosler LRX vs TTSX

[CanuckOutdoors]

Looking for some guidance on Barnes bullets for my 28 Nosler and 30 Nosler x bolts. 28 I have loaded up with 145 Lrx with h1000 and the 30 nosler with the 200 Lrx and retumbo. Both guns shoot well with the current load but wondering if I would be better off with a TTSX offering (150 for the 28 and 180 for the 30) as I have never shot over 350 yards on an animal.(heavy timber/cutlines). Done some reading that the LRX don’t perform well under 300 yards. The 28 is used mainly on black bears, deer. The 30 I plan to use for moose and elk. Also noticed the ttsx are a much shorter projectile. Thanks !
