Re: Remington 700 Mountain Rifle (blue) in 260 Rem
IMO, great little rifle, easy to carry, point and shoot. I had the Mountain Rifle LSS (Laminated, stainless steel) in .260 Rem and it will flat out slap a whitetail down. I bought it for my son but he outgrew it (so he thought) and had to have my .25-06 Sendero.
I loaded both the 100 and 120gn Ballistic Tips for it and it shot sub 1/2" (usually .3-.4's) but you have to let the barrel cool between shots while doing load development.
For the 100gn NBT I settled on 43.0gn of IMR4064 and CCI BR2's. The tightest group I shot with this load during development was .2565". I started out at 39.0gns and goups ran dime size, so it seemed to like this powder/primer combo throughout the range. For the 120gn NBT I used 46.5gn of H4350 with Remington 9.5 primers and it averaged 2980fps.
My 16yr old son could routinely hit 20oz Mt Dew plastic bottles filled with water at 500yds even with a Leupold Compact 3x9 scope on it. He was hell on whitetails with that thing.
I took the pressure point out of the stock's forearm and although it didn't affect the overall accuracy or consistency of this rifle either way, I did have to re-zero it. This wasn't your ordinary zero shift either, I missed the whole backstop (3'x3') with the first two shots at 100yds. I had to move in to 25yds to find out which direction it was shooting! Thought I had messed up, but once I dialed it back in it went right back to printing tiny little groups.
I recently sold/traded it to my boss man and he's very happy with it and I'm happy with the deal also. Hope this helps. JohnnyK.
