Barrel Heating
« on: August 08, 2004, 10:19:06 AM »
I am shooting a ss 16.25" 300 whisper.  I was having trouble getting it scoped.  Changed scopes.  Thought it was solved.  Yesterday I was shooting up some loads.  I want to change to one load, rather than 2 or 3.  My point of impact changed.  My best guess is that it is barrel heating.  Anyone with similar problems?

Barrel heating will throw off your accuracy. You need to let your barrel cool when trying for groups.  :D

Ruskin,
The hardest thing to do is shoot in a load without getting the barrel hot. I have found if you will take a couple extra plinkers say 22 lr with you and do a shot or two then plink for  a few, Makes your time go a lot faster. I know there is 60 mins in an hour but it seems like a lifetime when you'r waiting to take that next shot. It works for me. Good luck.........Joe........

We all do things different.  When I'm shooting one group with a bull contender barrel I shoot very fast.  Get set on aiming point and fire.  I usually shoot 5 shots in a minute to minute and half.  I do wait until barrel does cool some before shooting another group.  With a short stiff contender barrel I feel I'm done with group before heat causes a problem.  As I said we all do different things.  It doesn't mean I'm right and others wrong its just the way I have always done it.  Let me qualitfy that I only shoot small cases with max powder of 32 grs of powder.  The larger cases with more powder will heat up quicker.

With my Fox Ridge heavy .270 winchester barrel I fired 7 shots just as fast as I could stuff em in the pipe and get on the target.  The first 3 went into .5" and the last 4 went into .5" at 100 yards.  The last 4 did shift down almost an inch from the first group, I assume heat as well?  I was just curious how it would handle the heat and trust me it was smoking when I got done.  For my purposes (hunting) the first shot is the one that counts and it was on the money.  No doubt heat can/will affect point of impact in some rifles.
