1. Remington because I like their triggers more than anything else stock to date & seemingly, out of the box accuracy of their bbls is as good as I'm capable of for a hunting rifle.
2. M7s due to the light(er) weight & portability for the use I'm most apt = under 300 yd shots (mostly big game hunting applications in Colorado & packing an extra pound or two less is a perk) - a bit longer bbl = 20"+ would enchance velocity a bit & something I could live with. We're using the 18.5"ers currently. Have yet to see anything negative re the "loss" in velocity = put a good bullet where it's supposed to go & things fall down.
3. Currently = mine .308 Win - which covers everything I "have" to do in one caliber. As much as I am a .243 Win snob, that caliber just doesn't adequately cover larger game. I think I could be talked into a 7-08, with the right bbl length/velocity/twist combo - perhaps a nice blend of the lighter bullets for increased velocities (= varmits) & still the capability for heavier/SD bullets for larger game. I have been told that 7MM is THE perfect caliber for all things good ... I dunno. We could talk ....
4. The Wife's M7 (a 7-08) sports a Luepold 2X7 compact - a very nice scope & tough to beat for the compact/quality & priced-right package. My .308 M7 hangs under a Bausch & Lomb 2X8 compact (a discontinued model - alas). Lower power scopes allow very quick target acquistion at short(er) range & the variable mag affords a bit of the "extras" for a longer shot, if required. Both, after equating duplex subtension, will drop a bullet into the boiler room to 400 yds & that cover the bases for everything we'd want out of these shooters.
5. Covered above.
Things I'd change from what we got:
First, a detachable magazine, but purely for convenience - it has yet come into play in a hunting application. I'd still like to have it.
Too, These M7s seem to have a shorter magazine than is the throat which precludes seating bullets out more so towards the lands for fine-tuning handloads for full(er) potential. Still, hasn't seemed to matter one whit re accuracy - bugs me tho'.
Think I'd rather have a 20" bbl, all things considered.
With the 18.5" bbls, et al, it is a bit difficult to shoot to the rifles' potential soley due to their weight/mass - they are a bit light. Just not enough there to properly seat the darned things in a bag off the bench & stay there. Never a problem in any realistic hunting application - quite the opposite - I suspect it's a fault of mine & not that of the rifles' ...
Other rifles I'd rather use for different scenarios ("bean field"-type = way longer range or varmit apps, stantionary/stand-hunting, etc.) but for what we do most, I'd be hard-pressed to change my mind.
