AT TG 5150,.. When choosing, a Bullet for my .270 WSM, I read a LOT about, WHAT,.."worked".
When I shot, a 7mm Rem Mag., a couple of years back, ( it was a nice, Rem Rifle), I just hated, the 26 inch barrel, getting caught in the brush,.. all too often ( LOL). I used the 154 grain Hornady InterBond at, 3,070 FPS ( fast, as I could get accuracy, as any more and the groups, opened up ! ). The InterBond bullet, was probably the best bullet, for, Mushroom and penetration that, I ever shot! Bullet got to .750-.800 diameter "Mushroom's", and they went through,..a 15/16th inch OSB board, 12 inches of Gelatin and 4, one gallon water Jugs at, 100 Yards !
But, the Rifle was a full Pound heavier and 2" longer than my Tikka, .270 WSM. I thought those were good reasons, to buy a New Rifle,.. LOL !
I seriously doubt that an Elk could tell the difference between the .270 WSM and 7mm RM at, "reasonable ranges" with, "GOOD" 140 to 160 grain Bullets,.. out of either !
NONE ever complained, anyway !
