i have a remington model 700 7mm-08 sps stainless steel. i shot about 80 shots out of this gun and the accuracy of this gun went 2 an ok deer rifle to a horrible choice for anything. i would say its the barrel but my uncle has the same gun just in a different caliber and he put a douglas premium barrel on his gun and still cant hold a good group. i have a 4.5-14x40mm nikon buckmasters scope on my gun and i put a bell and carlson fully aluminum bedded stock on it and still my group is about 2 inchs at 100 yards. i reload for this gun but use very precise reloading. with reloads or factory loads i can not get a good group. if you can help me i would REALLY appreciate it. thank you keaton

Check the crown on the barrel for burrs. Next I would invest in a good bedding job. Have you checked the scope bases to make sure they havn't loosened up? Very unusual for a 700 to do this, my 25-06 will shoot anything I put in it accurately as long as it isn't moly coated.

I shoot a Rem 700Sps for 1000 meter tactical. Did the loss of function happen after you changed the stock? I would also look at the twist rate and match it to your bullet weight (bullet not fully stabilized), and chrony the load. 284 / 7mm 1:11 up to 140 grains 1:10 Magnum velocities 1:9.5 140 grains or more Was the barrel head-spaced with gauges? Lastly, my Rem is VERY picky about proper and even torque to the bottom metal to the action.

i have a factory barrel on the weapon. the rate in twist is 1 twist every 9.25 inches. i shoot a 139 grain hornady SST bullet with IMR 4895 and IMR 4064 and i also have tried many factory loads. i have shot a 162 grain bullet but still same accuracy. the problem started occurring with the factory stock then i put a bell and Carlson stock on it. and have seen no improvement

Is the barrel free floating? Have you had known good shot try it? If it has iron sights remove the scope and see in accuracy improves with open sights. I suspect the scope but only by eliminating possible causes can you discover the real cause. Good luck and keep us informed. That rifle is usually very accurate.

Do you use a cartridge OAL comparator to set bullet length?
Most Remingtons I've seen lately are so lawyer heavy that the chambers are cut so deep that after the barrels were machined to get back to max SAMII specs we were reading Remington upside down on the right side of the rifles.

Did you do anything different at the time when you went from an "OK" deer rifle to horrible.?
I see that you have done some work here with the new stock. Did the gun shoot better or worse with the factory stock?
I would start at one end of the rifle and work my way through it in that direction. If you think its the barrel have you tried to use JB bore cleaning compound on it yet. Don't get drastic, but just give it a good thorough cleaning. Inspect the crown, if you can get a borescope to do it with that is the way to go.
If you don't see any changes or find anything wrong I would look at trying a different scope.

take some shimming material (ie: thin cardboard, the silver gum wrappers work) and try slipping them under the barrel at the end of the forearm to apply light upward pressure to the barrel, start light and work you way to where you have 5-8 lbs upward pressure on your barrel see if somewhere between none and 8 lbs doesn't bring it in. If it does then all you have to do is remember the number of pieces of what ever and put a 3/4-1" band of bedding material under the barrel

Sounds like the scope went on you. If you have another scope put it on and try it or borrow one. Some times they just let go and thats it.

Try shooting your uncles rifle that is a proven accurate firearm. If your groups are bad with his rifle then you will find the problem is the man you shave.

did you buy this rifle new or used?
did you get scope eye, tagged, or hit at anytime shooting this rifle? my son can shoot my savage 10ml II all day long but put him behind a 300 Win Mag and he'll flinch every time....they both kick about the same, he just got tagged good with the Win Mag and now has a problem holding tight groups with it...(all psychological)
to find out if it's the rifle or the scope or maybe the shooter.... try these two tests...
(A) put the scope in question on a rifle that you know holds tight groupings.....fire for grouping, zeroing is not that important just get it close at 100 and fire for grouping.....(ensure scope is straight and level with rifle)
(b) put a known good scope on the rifle in question....and again fire for grouping .....(ensure scope is straight and level with rifle)
both test let barrel cool between shots and calm winds....
if only (a) will not hold a good group then you know it's the scope if only (b) will not hold a good group you know it's the rifle... if both (a) and (b) will not hold a good grouping then you know it's the shooter.....
I would suggest you have someone else do the same testing at the same time to rule all other possibilities ie.. shooter flinches with the rifle in question only and no other rifles.......thats about as close as i can get ya......

Not to be condescending but, How often do you clean your barrel? My 700 Stainless .300 Win Mag has to be cleaned after every ten shots to stay accurate. If I clean it like I should it will hold half inch or better groups at 100, and 3/4 at 225. Also many 700s HATE average factory ammo. my best factory loadings are hornady heavy mag with the old interlocks and PRVI Partizan 180s. I know it seems those are on the two extremes of factory loads but that is what it likes. it will not get better than 1 3/4 at 100 with 165s and 168 grain bullets and they have to be seated long. Do some experimenting with other than your standard remington and winchester factory ammo, sometimes they just don't like it. With remington factory ammo the best I have had was 4 inches at 100. If you reload, even better. Find out how long your throat is and get it about .010 off the lands, pay no attention to the COAL listed in the manual, that was for their rifle. try heavier and lighter bullets either way and see what it likes best. 700s are finnicky but can be extremely accurate.
