That's a nice setup 2muchgun.
I'm a 270/308/30-06 shooter mainly, but I admire the 7mmRM; I see it like a big brother to the 270 Win.
But my favourite 270 Win / 7mmRM rivalry story is about my best mate who'd been knocking my 270 for years because it was weak compared to his Big Seven...
We ran them both over the chrony, both using 150g bullets with our own respective handloads.
The 270 Win cracked the 150g SSTs at about 2975fps. Shoulda seen the look on my old mate's face when his 150 grainers clocked 2670fps!
Still killed pigs and deer extremely well I have to say and with a little more coal on the fire his loads soon were making more respectable numbers.
