A short and long action 700 build. Looking for tack drivers, what you recommend?

As VT notes above. If the goal for the short action is tiny groups at 100 yards, 6mmBR seems the obvious choice.

What is the goal for the long action? I take that since you are thinking 300 RUM, it is indeed a Magnum length receiver. If the objective is "go big or go home", 300 RUM will definitely let you stay out well after the street lights come on. But the 300 RUM is definitely a hunting cartridge rather than a target cartridge and, really, all the full length Magna are. 200 grs at 3150 fps is certainly going to be flat shooting and hard hitting. But the cost is pretty significant recoil, roughly 36lbs, or about the same as a 375 H&H chucking 270s at just under 2,700 fps...

The 300 RUM is definitely a statement. But unless you hunt elk at 500 - 600 yards, it seems a little shouty, a bit short, tubby, bald guy in a Corvette, I'm afraid.



I agree. Maybe the OP should look into a 338-06 since he already has a 35 Whelen? I'm pondering a 338-06 myself as a 400yd deer and hog rifle.

If 100 yds is going to be the norm maybe just accurize the AR with a new barrel, BCG, and trigger.

Short action —> 6mm BR.

Absolutely, the 6mmBR is the KING for that purpose

For outshooting your drinking buddies at 100yrds, I'd go with either a .223Win or 6.5 Grendel in a Remage 18" bull barrel. Don't need a lot of velocity to get to 100yrds.

Low recoil will make taking their lunch money easier for sure.

What calibers/ level of equipment are they running? Are they shooting Mosins and economy hunting rifles? Or are they running tuned up bolt guns too?

If you really want one hole groups, you should be handloading.
