Sticky Bolt Defined

Wanted to get some feed back on this. I have been reloading for about one year, things seem to be going well. Im always reading that one of the signs of High Pressure are a sticky bolt. I've only had one occassion were I was pretty sure the bolt being sticky was a sign of the high pressure because it was obviously hard to open. I shoot a Savage 10FP 308 and when thinking about it, the bolt could be considered sticky no matter what load was fired in it, as it is slight firmer to open than before the shot every time, but not necessarily hard to open. :confused::what:Any Comment?

The easiest way to find out if your rifle is experiencing high pressure is to shoot a box of factory ammo in your rifle and see what happens. I would suggest that you acquire several good loading manuals and read and understand the chapters on high pressure. Your sticky bolt is only one sign of high pressure and there should be several more indicators present. Please be safe. :)

If it opens harder than it normally does, you are having a sticky bolt.
You can't always eyeball pressure signs accurately. Sometimes they look OK and will let go the next reload. Other times cases can take severe overpressure to where the primers loosen up and fall out when you open the bolt.

Don't depend on it as a pressure sign.
Some bolts are just naturally sticky, like a lot of old mil-sups.
And others, like many of the new breed of custom-made, hand-lapped & multi-lug wonder guns, will be in blown-primer territory, long before the first sign of a sticky bolt.
It also continues to amaze me how many bolt-action rifles have never had the receiver locking lug recesses and cocking cam surfaces cleaned and properly greased.
A lot of them are so dry & dirty they almost squeak when you open them.

Heres another:

You can make a lug recess cleaning tool out of a wood dowel rod.
Cross-drill the end with about a 1/4" drill.
Then roll up a big shotgun patch, or pre-rolled dental rolls, and insert it through the hole to make a T.
Here is another set-up for AR-15's that uses little felt stars.

Once it is inside the receiver locking lug recess, rotate the patch & solvent, Keep doing it until it comes out clean.
Then, put a little dab of Lubri-Plate grease, or other good firearms grease on each bolt lug, and the firing pin cocking piece cam at the rear of the bolt.
Then work the bolt to spread it around in there.
Don't overdo it!.
Just a dab will do'ya!

Check to see if your front action screw is over tight. Loosen it a bit and see if your bolt works freer. I've had this problem in the past with some Savages. What is happening is that the screw is long enough that it maybe binding up the bolt which leads you to think that your load is over pressure.

You could try loading several rounds with the absolute lowest powder charge. Try firing them and see if the bolt is still sticky. Review the loading tables and create a round with the lowest pressure. If it's still sticky then consider other sources. Just my 2 cents.
