Re: Considering a Remington 700 SPS Long Range Any information would be helpful.
I can't speak to the new LR line; however, I would suggest that whatever you end up with to spend some time shooting the rifle prior to dumping $$ into it for accuracy. There have been a lot of people that speak to the poor quality of recently built Remington rifles - but they still kick some out that shoot. My dad bought a stainless sps last summer in 7mm Rem Mag and it flat shoots totally stock. This doesn't happen often but is possible.
The last rifle I bought, I bought knowing that it would be a good platform to build on IF it didn't perform to my specifications. It didn't and now it's a custom that does shoot.
As for the caliber choice, there is nothing wrong with a 300 winmag. If it were me looking for 1 do all deer/elk long range rig, I might choose a 7mm Rem Mag - it will hold it's velocity further out due to higher B.C.
Either way, let us know what you decide on!
