    I did some load's in the lead free stuff best of all was the 140g TTSX . 500 to 600 yards for a deer is as far as I think I will go at this time . going for a bear this year maybe 300 yards . I would like to practice out to 800 to a 1000 yards . The 150g TTSX was not that bad but my 5 shot group from the 140 would be inside the 5 shot group of the 150g . My big question is .. out of a 7mm rm is the 140g TTSX to light for what I want to do ? I dont need to hear about the other bullets I live in a lead free zone and hunt in it so lead bullets are out of the equation.

    What sized groups is it shooting and at what distance?
    That will determine whether or not it's worth shooting 800-1000 yds.
    Obviously you want the highest BC you can get with good accuracy.

    I can't really speak to the suitability for shooting bears although an extra 10gr won't overcome a poorly placed shot.

    Yes I know no matter what I use the shot must hit the right spot. The 150g best 5 shot group was over a inch. The 5 shot group from the 140's was inside 1/2 inch . A littel more info Barrel Length is 26" with 1 in 9-1/2 twist . I want to do this right the frist time thats why I am asking the qustion's .

    If you can get a lead free bullet in the 160 grain then that might be better for bear. My rifle would shoot the 160 grain bullets at about 3/4", 150's at 1 1/4" and the 140's at 3/4". I just couldn't get 150's to work

    The TTSX is plenty tough, if the 140s are shooting sub half-minute then I think i would be done looking for another bullet. Start stretching its legs some and see how it does at distance.

    I will do just that . I would just hate myself if I got a nice rack at 600 and take the shot just to find out not enough bullet to do the job . guess I will just try some pigs first.

    Have you tried playing around with Nosler green bullet, and the Hornady GMX?

    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) :D

    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.

    I run the 140TTSX in my 284win. It shoots great out to 600yds. The Rem Mag should get you more than the 2850fps start that I'm getting, this should be a plus.

    I can't speak for the OP, but my partner is putting the 140 MRX out of his 7RM at 3200fps, It shoots darn flat inside 500.

    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.

    Best of Luck
