I have about 2,500 rounds in my stock Savage in 308. While shooting a match last weekend I was shooting some of my better scores. Then it went to hell. Shot a 98, 97, 98, and a 99. Then two 91s back to back. The problem was verticle stringing that did not begin until after about 8 rounds down the barrel. I gave the rifle a good cleaning and today tried to replicate this event. It happened again after about round 7-9 on two different strings. Went from shooting 10s and Xs to high and low 9s and an 8 tossed in for good measure. Suggestions??

Re: Savage F/TR stringing when hot
That could be either your form during the recoil. You have to be consistent, or it could be neck tension, but my guess would be your form. I doubt that the barrel suddenly heats up.
Another possibility is cooking the round later in the string. The action heats up, you chamber the round, the concentrate on the sight picture or more likely the wind and let it sit there for 30 seconds and get really hot. Powder burns faster=more MV=high shot.
Three possible options.
I doubt that the barrel is suddenly getting hot, that causes the rounds to walk and you'd dial that before it got to the 8.

Check action screws and scope rings.....sounds like something is loose or scope malfunctioning. .....Or what XTR said.

At Sac Valley it is called The Wind. Does it do that when you load test at 100 yards?

An increase, or let off, in the wind generally does not result in high and low flyers.

Start with the basics, stock screw torque,(Stan Pates article is a must read) scope screws loose, bad scope (parallax went out on mine once, drove me nuts) firing pin issue,(weak spring, inconsistent ignition).

Depends a lot on your range topography.

If its on there from the factory, it ain't coming loose on its own
If you re-installed it and didn't torque it down enough... maybe. A quick check should answer that easily enough.
I've had *one* (out of more than a few) factory barrel that changed POI noticeably as it heated up, over the first 3-6 rounds. But it did that from the start, not just suddenly out of the blue 2500rds down the road.
I'd check the tightness on *everything*, including scope base screws, scope ring screws, action screws, etc. - it sounds like something is coming loose a few rounds into the string, or else you're changing something in the way you hold the gun (head pressure, shoulder pressure, resetting the bipod and/or rear bag) around that point. At least thats what I'd be looking for if it were me.
