Welcome to LRH! You will meet many knowledgeable, and helpful people on this site. I have a regular Rem 710 chambered in .270win with a Buckmaster 6-18x40 scope which I just love, I have gotten 1.5inch groups at 515yds, plus hits on milk jugs out to 700+yds all with off the shelf Hornady Light Mag 140gr. BTSP Interlocks. at 3100fps. I looked on Hornadys web site and couldn't find any ammo for .270wsm? Black Hills makes a good looking load which is as follows...
.270 WIN. SHORT MAG.
140 Gr. Nosler AccuBondTM
Velocity 3100 FPS
Energy 2987 Ft. Lbs.
But, Federal has the same load that puts out 3200fps and 3183lbs. I obviously haven't shot these loads, but maybe someone else can comment on them? Good luck.
