Rem 700 sps throws random fliers updated post 51

An it just never ends. I took the walnut classic style stock and ground out some of the bedding to use it on the 06. I got a nice fit on it and perfect for rebedding and trying it out. Turned it over and the damn sps trigger guard fits.. BUT.. will have to be inletted deeper into the stock. I drop the box mag into the action and put the trigger guard back in. Yup it rattles and doesnt fit into the trigger guard because the guard is to high. So evidently the BDL and SPS use different trigger guards and maybe box mags also. The classic stock was off my BDL 340WBY. so I know where it came from.. Does this crap ever end?? An of course I dont have spare BBDL parts sitting here either,

So if I dump the cash on a B+C stock am I going to run into the same problems and be looking for BDL bottom metal?
 
OP,
Inlet for a ADL mag box & BDL mag box are different....obviously.

Inlet for a Walker trigger group & X Mark trigger group are different.

Throw the TupperWare SPS stocks in the trash & upgrade.

Bed/pillar,float.

clean & lap the bores of both rifles before wasting any more components.

Make sure the mag box is free floating in the well. You want the action to sit on the pillars. not the mag box.
 
Powder, ammo, epoxy,your time all adds up .
If you doubt the rigidity of the stock invest in a better one instead of all the messing and guessing.
Just buy one to start and go from there .Bell And Carlson are reasonable enough .They still should be bedded at least in the recoil lug area.I personally like the wildcat fiberglass stocks but they are a raw blank and need to be finished .They are as stiff as they come with inner and outer fiberglass structure unlike some of the others that are cnc inletted from fill on the inside.
Also your inconsistencies could be coming from barrel,action and chamber misalignment.Quality control on the Remingtons SPS models is questionable at best .Have a look at your rifle bores thru a borescope it might horrify you.
I had a gent bring me a new take off sps barrel and wanted it indexed and head spaced on another rifle.I could not do it as the barrel shank and the chamber were to far out of sink .If I trued the threads and shank the chamber ran out .060.

I've have had good luck holding the forend while shooting lightweight rifles at the bench. This one was spraying them all over the place until I changed how I shot it.

I rest the forend on the shooting rest and hold it with my hand behind the rest. This controls muzzle flip. Make sure the sling studs don't contact the rest or rear bag.

Thats the way I usually shoot unless its one of my big bores. Right hand on the rifle and the left hand makes a "V" with thumb and forefinger that then sits against the rear of the front bag. The left hand just lightly holds the forend with no real pressure on it but more of a stabilizing guide.

I usually shoot with my left hand under the buttstock for making teeny adjustments, but when I taught my son to shoot it was with his left hand under the fore end, mostly in preparation for shooting heavier kicking rounds, but also it seems he's fairly consistent with it. I've started shooting like this as well - light grip on the front really helps with some rifles. My Vanguard in .257 Wby LOVES it. .8 MOA 3-shot groups at 200m.

This is turning into a personal challenge now with this stock. The 3 rifles were doing the same thing and somewhere in my skull lies a answer. At least I got the .223 shooting .690. Stu, who builds the wildcat stocks is a friend of mine. I know all the materials and time add up,but it would drive me nuts now to just give up on it. I am on a mission!!

I was wondering this after you posted and finally checked it out. When the rifle is put together the mag box is tight. This could be allowing the rear of the action to have a slight left/right movement or bowing the action/stock when tightening it down. When I got the 06 ( it was used but mint) I remember that to get the mag to fit easily into the trigger guard when reassembling I had to relieve one stock wall slightly as it was twisting the box mag slightly. I checked the 300 box mag this morning and its tight and doesnt wiggle at all.

So next plan of attack is to full length bed the action and get rid of the gap between the receiver and stock at the mag box location. This should give me a nice stress free fit. But firstly I need to either just put a thin washer or two under the trigger guard to get some "play" in the box mag. Or maybe file the bottom of the box mag to allow clearance and looseness. Not to much but just enough to have it wiggle ever so slightly. Or I could just try relieving the box mag and try shooting it again. Meh,probably bed it first.
 
Not the same as your rifles, but multiple mausers in various stocks here that others had worked on. Many have 5/16" or 3/8" washers between stock inlet and the bottom metal - got moderately "good" at holding the washer with big linesman pliers to grind to shape on bench grinder to fit into inletting with hole still centered. Gave up being amazed - in many cases, all that the washer did (often one front and one at back) was bring the bottom metal back to the level of the stock - inletting was too deep - so magazine box was tight to the receiver when action screws snugged up. And discovered that 50 or 100 washers in a bag from local Co-op Hardware store actually gives you a selection of thicknesses to chose from...

EDIT - foregoing was mistaken! The washer under front was on a Win M70 in an aftermarket stock!! All the mausers here have got that ferrule at the front that sets the spacing to the lug under the front receiver ring - but several mausers required that washer under the rear action screw, or that rear pillar to be "sticking out" from the stock inletting to get an air gap between receiver and the top of the magazine.

On numerous remingtons I have owned new and used they usually had washers. It might help,might not but its worth a try. At the very least any one reading this thread can learn from my experience and time and $$$. It would be a quick way to test a theory,but may not be quite correct. The mag being tight has got me really thinking about what the stock is doing when you tighten everything down. Its a good thing I dont need these rifles this year!!
 
So a update. I full length bedded the receiver. I noticed some side to side play in it one day with the action screws out. Bedding cured that and at the same time I ended up putting a couple of very thin Remington washers under the trigger guard and got the box mag to free float. Back to the range with the same loads and still getting random fliers and not a group but more of a pattern. So playing with it some more I took the scope bases off and be danged the back base would rock side to side. So I ended up bedding the bases and lapping the rings. I also had some left over 180 grain Partitions as I was using 150 partitions before and picked up a box of nosler Ballistic tip 180 grainers. Upon pulling the bases off the rear one, before bedding, was only getting about 50% contact...ahh hah...maybe now?

So today at the range I fired 3 rounds of the best load/powder with the 150 partitions. I got a 1 1/8 inch group. Yes a group with 3 shots and not a average over 5 previous targets. Next up was 3 different loads with 180 partitions which all averaged 1.5 inches, I need to drop that load a bit and retry it when I can find more slugs. But it was a group with no fliers or funny crap going on!
Next was 3 different loads with h4831 and the ballistic tips. The first load was 1.5 inches, 2nd load went 1 1/8th and the 3rd load dropped 3 into 5/8ths of a inch. I think that the bases were jumping to where ever the stresses took them and causing me grief. Of course all the little things added up and it was a lot of work and fiddling and $$$ but at least I have a rifle now that I can feel comfortable with. It was a good learning lesson and a test of me not wrapping it around a fence post.
 
Sometimes it is the smallest of aggravations that go unnoticed.

I remember a story about a Merlin engine in a Mustang race plane. The owner had spent buckets of money getting this engine through rebuild, putting in really expensive parts, and giving it all the care it deserves. But there was an unexplained vibration at certain RPMs. No one could find the problem until someone noticed a decal on one propeller blade that wasn't on the others. They did a balance test on the whole prop and that little circle of vinyl was causing the problem. Off it came, and the plane went on to be a serious challenger at Reno.
