Re: Barrel life question
Sounds like you need the 7mm08 or the 308. They offer better barrel life and offer better terminal performance further out than the 260 remmy.
You say you want to shoot alot. The 6.5x284 is murder on barrel life. It is an awesome round but leaves alot to be diesired for guys that like to shoot alot.
There is nothing the 708 or 308 cant do that the 260 remington can EXCEPT for have equal wind drift for the same amount of recoil. you can actually get less wind drift with the 708 or 308 than the 260, just with more recoil. A common misconception is that the smaller the caliber the higher the BC's and that is not true. It is typically true that equal weight for equal weight of bullet, the smaller caliber will have a higher BC. The truth is that the larger the caliber, the higher the BC potential. Unfortunately, with higher recoil. On the other hand, (all other factors being equal) the larger the bore, the faster you can run bullets of equal weights from a smaller caliber.
The 162 AMAX (7mm) and the 208 AMAX (308) have super high BC's which helps them dope the wind better than the 140 class bullets. With the added weight for energy and higher BC for less windage, the 708 or 308 is a fine LR deer caliber that you can milk ALOT of freakin rounds through and still have manageable recoil.
FWIW, I am running 200 SGK's out of my 308 winnie at 2675 FPS and 208 AMAX's at 2650 and am working on a load that tops out at over 2700. Either load would dispatch a deer way the heck out there. I know other shooters running the 162 AMAX out of the 708 at 2750-2800 FPS. If you run those numbers against the 260 remmy, I think you will be suprised. The 260 would make a fine match rifle due to its low recoil and decent ballistics but from an energy standpoint from a case that will offer you long barrel life as well as long range deer performance, the 708 or 308 will be tough to beat short of stepping up to a short mag.
The 260 remmy, the 6.5x284, the 708 and the 308 will ALL shoot sub MOA at 1K yards.

My answer to this is. The only reason is to make the 7 RM look good. There is no other reason.
