Remingtonfan--usual Tuneups
I was referring to the usual "tune ups" for any rifle that isn't shooting fairly good groups.
1. Check to see if the barrel is touching the forearm. If so, clean the channel out to prevent that by sanding the areas that are touching. Some say a composite stock like the one on the SPS doesn't create accuracy issues, but I don't agree. If you can't slide a dollar bill down the barrel between the barrel and the forearm, work on the channel.
2. Adjust trigger pull. My SPS did not have an adjustable trigger, and it ended up wearing a Timney trigger that works great. The factory trigger was not good--creepy and heavy pull. Be aware the if you change the trigger, and you send it to Remington for factory work, they will take the tigger you send to them off and replace it with one just like it came with and charge you for it. Thank the lawyers for that little goody.
3. Check action screws to be sure they are torqued correctly.
4. Scope mounts and rings.
5. Try various loads to see if the firearm likes something from the factory. Or if you handload (and just loads of fun and time involved) try various loads to see what shoots good.
Heck I dunno--I ain't no expert, and only get things right by trial and error, but mostly by luck.
