7mm r-m 140g TTSX

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.

Re: 7mm r-m 140g TTSX

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?
