Barnes LRX in 7mm-08?

[Buck13]

I read that the Barnes LRX is designed to expand at lower velocities than their TSX series. This sounds like it might be good for use in the 7mm-08 in an Encore pistol. Any facts or opinions about how well that would work? I'm also potentially interested in it in a rifle.

Load data for that bullet seems pretty scarce. Has it shown up in any of the newest manuals? (My newest is Lyman 49th.) Western Powder's website has a lot of data for the TSX but not the LRX. Anyone concerned about using their data for the TSX of the next-heaviest weight? (i.e. 140 gr TSX data with 139 gr LRX and 150 gr TSX data with 145 gr LRX)

Not a huge difference between ttsx and lrx, are you already familiar with shooting monometals?

I'm not. From what I've read, many people find excellent weight retention and performance, and a few seem to get no expansion or at least low wounding that could best be explained by that.

I don't know how I looked at their site repeatedly without seeing the load data link. I wish they made it a bit bigger!

When pushing a monometal, speed is your friend, I try to keep impacts above 2000 fps. I like em on hide critters because the exit wounds are tiny comparatively, and they keep a better bc than the traditional lightweight varmint bullets. You can utilize lighter than normal weights and still get better penetration than cup an cores, I'm partial to pro hunters and ballistic tips for deer, anything bigger/tougher, I like the bonded bullets or a-frame types, but without knowing what your purposes are, I'd start with the 139 gr, some Imr4451 (hodgdon has data for a 139 gr hornady, and that's a decent place to start) and try to get the mv above 2800 and the groups under 2.5" and report back with the results. Good luck to you, I'd also advise emailing Barnes and asking what the expansion window is for the 139 and 145 gr bullets, if the 145 expanded MUCH below the 139, it might get my attention instead.

Got a reply on Monday:

The 139 gr. LRX will expand down to 1400 fps. Thank You Ryan Farr | Tech Support/Consumer Services Lead Barnes Bullets

Kinda perfunctory, but sounds like they would work. He didn't answer the part of the question whether the LRX is actually easier-expanding than the TTSX. I guess that's a trade secret. Fair enough.
