I just purched a remington sps tactical the stock has to go. but on measuring the throat legnth i found it to be .135" long. My question is should i have the barrel set back and the chamber recut. and how much accuracy loss will this cause. I can not set the bullet out far enough to get a .010 to .015 jump to the lands. I am loading smk 175gr bullets. I plan on using this rifle out to 600 meters for our tacitical matches at our club. Thanks for the help.

Out to 600 you should be fine. I would say test at those ranges first to see how it does before you go sinking money into her that you may not need to.

I have Remington's with the factory long throat and I have one with a short throat. While I do not handload for .308win I have shot FGMM 168 in all of them and not seen any difference in accuracy

I have to load my 155 scenars to 2.948 OAL to be at 0.015 from the lands. This is typical of Remmington factory chambers.

2.948+0.015 - 2.820 = 0.143 or about the same as yours.

My scenars typically shoot one 0.35" 5-shot group, two 0.45" groups and one 0.60" group from a box of 20. This is just a tad better then FGMM 168.

I also have a magazine loading set at 2.820 OAL that shoots similarly at 125 fps slower.

So, don't fret the long throat, use it to your advantage.
