Bedding in front of the recoil lug?

Hello Everybody,
I have a Remington 700 SPS (sporter barrel) in the 7mm mag, laminate stock. I have been reloading and found a load that gave me .45 MOA. I was pretty happy with that for a factory barrel, but I wanted to pillar bed the action so that I didn't deteriorate the stock over time at the action screws.
After bedding, I am now shooting just over 1 MOA. I taped the bottom, front and sides of the lug and bedded about 2" of the barrel in front of the lug.
I am pretty sure that before the bed job, the barrel had no contact all the way to the lug.
Should I start shaving back the bedding in front of the lug and see if my accuracy returns. I am thinking this is probably the problem.
Any thoughts?

Re: Bedding in front of the recoil lug?

If you don't bed the front and bottom of recoil lug why would you bed the barrel at all?
I would remove the bedding in front of the lug and I bet your groups come back.
Other question would be what did you use for bedding?

I used the deluxe kit from scorehi.com. I think the bedding material is called pro bed 2000. I followed their instructions to tape the sides and bottom and front of the lug for clearance purposes. But they also insrtuct to bed the first 2 inches of the barrel.
So your advice is to just remove it completely? I guess I could always rebed that area if I needed to.

You had a factory sporter barreled 7 mm Magnum that shot .45 and you interfeared with it ? I don't usually say this kind of thing but that was real dumb.
The most likely cause is you have introduced stress in the bedding job.

Re: Bedding in front of the recoil lug?

why would you call someone dumb for wanting to make sure their rifle remains accurate over time??.. just becuase a rifle shot .45 without being bedded doesnt mean it will stay that way.. bedding a rifle insures the same accuracy no matter what the weather and temp is.. so maybe your retarded? you should always bed 2 inches or so infront of the recoil lug.. I know smiths that bed the whole barrel channel.. you make sure youdo not have any high spots? that everything was true when you installed it after the bedding compound was applied.. bedding compound shouldnt make too much difference I have used jb weld for christ sakes.. it may be now thats its bedded you have changed the harmonics of the rifle.. and you may need to find a different load for it.. im not a gunsmith but i would make sure you dont have any contact pointsin the bedding proccess..

kasey

Re: Bedding in front of the recoil lug?

I appologise for being rude but it may have been better to wait untill it stopped shooting .45 and then try to fix it . Now you have a 1 MOA when you had .45.
That surely can't be smart . Bedding properly requires skill and experience and it is very easy to screw it up even the pros screw up now and then . Have you not heard the old addage ? If it's not broke don't fix it .
He need to do research on how to do a stress free bedding job. I hope that may fix it. However don't be too dissapointed if you never see .45 again. I hope you do get it back but also it may have just been a few exceptionaly perfect well matched bullets . I have bedded many more rifles than you sport and I was going to explain the process to him but it seems you know how to do it so you explain how to do a stress free job. I'm all ears.

Re: Bedding in front of the recoil lug?

I'm not frustrated with the change in accuracy. For me it is a good opportunity to learn more about how a rifle shoots. I'm not a perfectionist and I'm OK with how it shoots. I just wanting to learn more while dong a fun project.
Unfortunately I don't have an instrament to measure stress. However, I am pretty sure the bed job is stress free without any high points. The mag box isn't bound and the back of the lug is tight against the bed.
I shaved back the bedding in front of the lug leaving only about 1/4". After 1/4" the sporter barrel starts to taper. I read somewhere that bedding forward into the taper of the barrel could cause inconsistent harmonics. Anyway...I'll update you on if this makes any difference. If not, I will remove the remaining 1/4" of bed in front of the lug and shoot again.
Thanks for your thoughts.
