Author Topic: ENCORE Vertical stringing groups? (Read 1090 times)

My .308 24" ENCORE seems to like to string its groups vertically. What causes this and how can I stop it? I have heard some say it is caused from a hot barrel. I don't think this is the case with this rifle. I let it completely cool between shots. Does where you place the sand bag under the forearm make any difference? Should I try to shim or float the forearm with washers?
Thanks : :?

Where you place the rifle on the bags makes a world of difference. Consistency from shot to shot is one of the keys to getting TC's to group well. Floating the fore arm seems to help more often than not. One trick to floating one is to layer a couple of strips of electrical tape where the mounting holes are and seating the fore arm on the tape strips. KN

Ok Guys! The FREE FLOATING of the BARELL worked for me! :grin: I also worked on my BULLETS SEATING Depth. Just went twenty thousandths from the bullet touching the lands and bingo.

My 165gr Rem PSPCL bullets went from 3" down to .800" just with floating the Bbl and seating the bullet to 2.7555". Im burning a max load of IMR 4895 and Fed 210M primers tucked away in WW brass. Can't wait to try it on a couple deer and see how they perform. I think my BIGGEST problem was the BARREL touching the forearm in about four different places. Now that this problem is cured, I feel confident that all my reloadings from 125gr up to 180gr will be much simpler. Now to get my 7MM MAG barrel tuned up and I should be in business. Thanks for the help!!!!! :grin:

I was having the same problem with my 30-06 and 223 Encore barrels. It came down to clean versus dirty barrel. If I cleaned the barrel, the first shot was about 12" high at 100 yds. Each shot is a few inches lower, until they reached 0" high. Windage was unaffected. Now, once sighted in, I leave the barrel dirty until the season is over. You might want to try running a clean dry patch through though. This is a known issue at TC.

Guess I am the odd ball out - my groups always string horizontal. :?

Vertical stringing is due most often to to variation in ignation, usually due to primers. It can also becaused by by a difference in bullet pull, it takes more or less presure to pull the bullet from the case. It could also be caused by barrel heating. If they always run in the same direction that would be the first thing I would look at.
