yes I have tried the nosler's but they are not consistent at all. the hornady I have not tried . but hornady only offers 139g in the 7mm and the barnes is 140 and real good groups.
Okay, thought I would ask. I have heard different reports on the Nosler. I haven't heard much on the GMX, but what I have heard has been positive. Any chance we can see the rifle?

Just got back from Africa 3 weeks ago. I used a 7mm w/ 150gr TTSX. Killed Kudu, Lechwe, Bushbuck, 2 impala, Blesbuck and others with no trouble. The 140 will do the same. 2 yrs ago recovered one from a .270 in the 130 gr. Went through about 30 inches of mule deer body. They are a good bullet.
In Africa my son took his .243. He borrowed my 7mm for Kudu. On his Lechwe he had a bull at 160 yards. Waited for 10 min for it to clear the females. The Landowner told him to shoot and to squeeze the trigger. As he shot a young male jumped out and stuck his neck in the way... When they walked over BOTH animals were dead. 80 gr TTSX. Through the neck of the first Lechwe and ALL the way through the big bull...... Believe me there isn't a black bear out there that I would hesitated to shoot with the 140 gr TTSX if he gives me a good shot. You are getting great groups and it will kill them if you do your part.

I agree with Gillette hunter (& no, not just because I live in Gillette)
My hunting partner uses the 140 MRX to great success out of his 7mm, accuracy is awesome & terminal performance is second to none (he's only shot to 300-400). The 140 TTSX will, in my opinion, devastate a black bear with authority, the caveat being the BC of a listed .412. Now many shooters have found that Barnes has been somewhat conservative with their BC's but YMMV. Keep your shots inside 500-600 & I think you will be very pleased with what you find.
There was a recommendation for stepping up in weight, fine, if you are going to use a bonded core bullet. It's my personal belief that the 160 TSX (& speaking about the TSX only), is on the line as far as acceptable velocity & gyroscopic stability are concerned. I have never witnessed, but have heard & read both, many accounts of poor performance from the 160 TSX out of the 7RM, some of which have been posted here. I would have to recommend the 150 as an accepable ceiling as far as weight is concerned out of a standard 7RM.
TF, a friend of mine is a rep for Barnes bullets and got me hooked on them many years ago. The BC's are lower than many of the target bullets out there. But what I can tell you, from experience, is that 140grns is more than enough for what you are looking to do. A few years ago I shot completely through a 300lb mulie with a 100gr bullet, out of my 257weatherby, at more than a stones throw. I have also used them in my 35whelen for bear, 243win for whitetail, and 300weatherby for caribou and bigger animals. As of now I have recovered very few of the bullets. Penetration is hardly a worry. Getting them to group is sometimes a chore. However as recommended, you must play with the seating depth. Most of the calibers I shoot require a deeper seating depth than any other bullet used for that particular caliber. But when you find the sweet spot you will know it right away.
