walking remington

is it common for a remington 700 groups to walk (upwards) as the barrel gets hot? i have had this particular gun for over 15 years, but never had a decent rest before, so now i am noticing this. before, all i had was to lay it across the hood of the truck when practicing / sighting. is there anything i can do to help this? it is not horrible, and to be honest, it is a hunting gun. so anything more that 3 fast shots is pretty much all but imposible. it is just one of those things, now that i know it does this, that bugs me.:eek:

It's those two little nubs that press against the barrel in the forend and affect the groups as it heats up. If you are only going to hunt and take one or two shots and it hits POA on the first, then it's nothing to worry about.
I always float my bolt action barrels to eliminate that issue. I know a small minority disagree about floating, but I know it has worked for me and many others every time. It's your call if you want to knock those nubs down or not. You can always add shims if your not happy with the outcome.

Vertical strings are almost always caused by too much upward pressure at the forend tip. IMO, there shouldn't be more than a light pull needed to separate barrel and forearm; roughly five pounds at most. A gentle touch tends to dampen vibrations, making them more uniform.

Too much pressure, and it is then further increased by the expansion of the barrel as it heats with firing.

I like to free-float the barrel and then make a thin shim to just barely dampen the vibrations. It's always helped when I've started with less-than-optimum groups...

As barrels heat up thy get longer!
This will pull the point of impact up or down.
I have an 1891 Mauser that walks down up to a foot but less then 1 inch side to side.
Make sure the stock does not rub agent the HOT barrel.

well, i may try removing the pressure next year, or at least after deer season. it is to close to mess with right now. if i screw it up, i do not want to be scrambling at the last minute trying to get it back where it was so i can hunt with it. thanks for the info. i will mess with it, just not right now. at least it does not sound to serious.

Hi Moooooose....

Have Faith in the obvious... if the first shot hits the right spot the POI of subsequent shots never comes into consideration.

well, when actually hunting, i have never had to take a second shot. ever. the 300 win mag does a good job. and i do my best to do my part. and so far, i have done pretty good. i try to know my limits, and those of the gun. so far, i have only made one mistake, i shot through a small tree that i didn't see when shooting a deer. it turned out ok though. it was the only deer i ever had to chase, and is was slightly less than 100 yards. funny thing is, the bullet hit the spot i was aiming at even after going through the birch. lady luck does come around once in a while. the climbing is just frustrating when practicing, or like this week i installed a different scope. shoot a couple of rounds, wait 10 minutes, shoot a couple more, repeat as necessary. very time consuming. i would always check on a cold barrel. just because that is the most likely shot when hunting. in fact, when it quits raining, i will have to go out and do that again.
