She could easily shoot a rifle like a model 10 tactical Savage in .260 Rem.
The model 10 with a heavy barrel will tip the scale at around 13 lbs with a good
scope and bipod attached. The recoil of a .260 with a 140 gr Sierra HPBT match
bullet is very mild. But, the rifle is good to 1000 yards
due to the high BC of the 6.5mm 140 gr bullet and the velocity the
.260 can produce in a match grade round. The .260 is better then a
lot of similar 6.5mm cartridges because it can easily handle the 140 and 142 grain
bullets which have a very high BC. Also, the .260 is based on the .308
brass and you can make .260 from .308, 7-08 and .243 brass.
There are a ton of match grade commercial loads for this round as well.
It was used by G. David Taub to win rifle competitions back when
it was the 6.5-08 wildcat before it was commercialised as the
.260. Another European round that has mild recoil and can shoot 1000 yards is the
classic 6.5x55 Swede.
I completely forgot I posted this 4 years ago. Interesting to go back and see the comments, and see it’s still somehow semi active right now. Learned a bunch in those 4 years. Btw, since I’m sure the first question is gonna be what route I went, it was 6.5 grendel. Regret nothing about it either. Ended up parting with that action, and oddly enough the whole idea for a long time as I spent a year overseas and travelled a lot. Got settled in and reattached it last year and ended up just grabbing a Ruger American Ranch in 6.5 grendel off the shelf since I didn’t want to sink crazy money in case my wife ended up hating it. Things pretty nifty, topped it with a spare Leopold VX-3 I had laying around and have played around with it out to 600. Probably gonna get rid of it and get something fancy done though. Just happen to live down the road from Whidden Gunworks (Awesome guys btw) and they just finished my first attempt at a 1-mile plus gun. Might have them piece together nicer than that American.
