I haven't tried the TSX bullets in either my 300 or 338.They are great in my 7Mag. I would like to load them in my 470 double and just found out those bullets actually existed.I am considering playing with the new MRX in the 300 and probably keeping the Swift Aframe in the 338.Guess I am obsessive compulsive to change but wanting a better bullet is a powerful lust to have.

Bullet experience is highly individual but-

I have primarily used the Nosler Partition/standard Barnes X bullets in the past and they have been great on deer, elk, and moose with the NP loosing a signifigant portion of weight in front of the partition after impact(non bonded) and the X bullet tissue destruction being devastating with mostly complete penetration but loosing some petals retained in the large animals. My hunting buddies failsafes were very accurate but he never recovered one as they penetrated completely like a FMJ or solid. The wound channels just didn't seem to open up like my X bullets and the animals weren't as impressed with the hit as with his current bullet.He now uses the Nosler Accubond bullets in his 300 Mag.

Swift A frames are great and hit big bear like a jackhammer.They are bonded and very accurate in my 338.I prefer them over the NP because of the bonding/weight retention but Dead is Dead and the NP has worked great in my 300 mags.

African game is "tough" by reputation and I am leaning toward Barnes new MRX bullet for accuracy, expansion, and deep penetration in the 300 Mag.It has their copper X tip with a polymer insert and the rear of the failsafe/Swift A Frame/NP bullets with a tunsten insert. Their bullet promo stuff says the bullet rearward balance helps long range accuracy. We'll see. On the 338 I would just stay with the bonded Swift A Frame, kinda like a NP on steroids.I am tempted to go with the Barnes new MRX bullet but don't want to change from a winner.The Swift is plently tough enough.

What are your preferences?
