I've loaded the 145 LRX in my 7mm Rem mag for about a year. It's a stainless Win-70 with a BOSS and a VX3i 3.5-10x40 CDS.
The rifle has been a consistent 1/2" (3-shot) shooter with moly coated 150gr Swift Sciroccos and 140gr Barnes TSX.
But have since switched to the 145-LRX and also Moly-coat these first, in a simple Tumbler.
The last group of 5 LRX fired, went into .665 @ 100 My re-load data (from one of the plastic cases) is:
Nosler Brass, Fed 215
fired shoulders set back .002" ... to + .005 on an RCBS case gage
66.0 grs of RL-22
3.380" OAL
3070 FPS (measured on the ranges Lab-Radar, 10 yards from the muzzle)

This is just above the Barnes max level, with RL-22 . . . (the moly helps).
If they let us into the woods this Spring ... I'd like to introduce a NE Oregon Bear to the LRX.

Hope this helps
