Problem 700 SPS
I do a lot of reading on this forum and there is a ton of great advice so I thought I would join and post the problem I've been having.
At the right price, I purchased a new 700 SPS in 7mm Rem Mag 4 months ago and have been having issues with it. My goal with this gun was to be a project gun I could improve from year to year. My accuracy standard for this gun is at least moa as it will be used for shooting out to 600+ yards. This is my first Remington. Below are a list of problems I have identified:
1. First shot resulted in a case stuck in the chamber. (Was sent back for warranty work in which they replaced the extractor and checked headspace) After repair, extraction seams to function.
2. Brass cases have very noticeable scratches on and near the belt of the cases after extraction.
3. Brass shavings build up on the bolt face after a shooting session. Assumed caused by extractor and problems identified in item 2.
4. Cratered primers even on low pressure rounds (300 fps lower than factory velocities). Appears the firing pin hole on the bolt face is oversized.
5. Precision is non-existent
To expound on item #5, starting with factory Winchester ammo with 150 grain power point bullets, I could not group better than 3-inches at 100 yards.
Here is a list of things I have tried to improve the precision of the rifle and none have worked.
1. Had two friends shoot it and none grouped any better than 3"
2. Bedded action, made pillars out of bedding material, free floated barrel
3. Stiffened factory stock forfend
4. Used 150 grain Winchester Power Point bullets
5. Used 162 grain Hornady SPBT Interlock bullets
6. Used 168 grain Berger VLD bullets
7. Used 175 grain Nosler ABLR bullets
8. Varied seating depths from 0.010" to 0.150" off lands with bullets above
9. Worked up powder charges with IMR 7828 and H1000 and was able to get a couple groups around 1.5" with velocities 250 fps less than factory which is unacceptable. 3"+ at or near standard velocities.
10. Changed stock to Bell and Carlson Medalist, free floated barrel and skim bedded action.
So after $450 in shipping fees, ammo, and stock improvements with no fix in sight I am wondering what to do with this gun. I would much rather have spent that on a better gun as Remington is proving to be less than helpful.
Should I send this gun back to Remington and hope they do something that will get me at least MOA accuracy since it is still under warranty, mess around with other barrel bedding techniques, take it to a smith for evaluation and some work, or just sell the thing?
