Nothing wrong with either rifle, a critter shot with either isn't going to know the difference if it was shot with a 26" barrel or 24"or BDL vs SPS, it's like another post said above, maybe 60fps difference, if you like BDL go for it, I've had both I would keep stainless ONLY because you could easily find a factory REM 300WM STAINLESS take-off barrel, and make it 26" barreled action using a factory chambered Remington barrel (way cheaper than a custom barrel) if trying to save money. But, ultimately save for a STAINLESS cut rifled barrel (Krieger, Bartlein, Rock Creek, KP, or Mullerworks, Brux etc) down the road, and you will have a GREAT rifle when you are done.... along with being all STAINLESS only reason I say that is, if you hunt much it's going to get wet eventually and stainless is a BIT more rust resistant all things being equal.... I doubt the stainless 700 is any more or less accurate than the BDL if so the military would use all stainless for all their SNIPER rifles... UNCLE SAM tests more than any guy off the street... BDL blued rifles are a thing of beauty no doubt about it,
Get which you like BEST and don't look back, or get BOTH go shoot the crap out of both and tell us which one shoots best!
It's a REM 700 can't say I've ever seen one that doesn't shoot!
