How do you get rid of vertical?

[afy]

I am currently getting about 1 caliber worth of vertical, which is annoying to say the least. How do I get rid of it? All help and suggestions are very welcome.

Thank you.

Try more powder and/or more neck tension.

Different primers also.

How do you get rid of vertical?

AFY -

Howdy !

You did not describe the troubled rifle.

If you have a really long/heavy barrel, " barrel droop " might be one contributing factor.
1,000yd shooters often have rifles w/ " barrel blocks", to help
mitigate the then tendency of such barrels to be influenced by
'gravity.

Any undesired upward pressure on the barrel by the forendmay also contribute.

Verticle can also be encountered as the barrel heats up
during strings of fire.

I had verticle w/ my 29" barrelled 6mm wildcat, despite all attempts to provide a good conventional bedding set-up.
This verticle went away after I switched rifle to a barrel ]block set-up; and tuned the verticle out by gradually advancing the barrel block fwd; until the " sweet spot" was found.

Best of luck in your endeavors !

The rifle is a Savage 10 with a 26 inch 1:8 LW barrel. It is free floated, and two sheets of A4 paper will move freely under the barrel. The Rifle is aluminium bedded, and torqued to 40 lb/in.
The temperature at the shoot was -10 C, and the barrel did not heat up, mildly warm if that.

Neck tension is currently at 0.2 in, and I am upping the powder charge by 0.1 grain increments. Currently at 30.1, will go to 3.4 on my next range trip, while checking for pressure signs. Currently there are none. The COAL is 2.335 and the powder is varget. The bullet is the 105 Scenar, jammed 0.015 into the lands.

Check out Speedys article. This should give you some stuff to try. Just dont do it all at once. Do one or two things at a time.

A neck tension of 0.2" is through the roof. You may want to try .002 to .004" next. Also try incremental loading or a ladder test to see where the vertical stops. At 300 meters I would take a caliber of vertical any day. Have you shoot anything less in the past? It could be body English. Here is a link to ladder testing: http://www.scribd.com/doc/24325721/eBook-Firearms-Ammunition-Reloading-Incremental-Load-Development-Ladder-Method.

Another solution not mentioned here is seating depth. Try just touching and then move back at .0020 intervals and see if this doesn't help. Don't be too concerned about length, I've had then not respond until jumping them at 100's off.

Neck tension is .02 not .2 my fault.
I am trying to improve my bench technique, as well as play with loads. So far no real success.

.002 is probably more like it. What caliber are you shooting. My chamber (6BRX) is .270 and loaded my brass is .269 (107 and 105 SMK and scenars respectively). I neck size with 269-267.

It may also be too much powder.


What is "a caliber of vertical"? BTW.

 

[afy]

Limbic a caliber of vertical is when 4 shots go into the same hole, and one goes high touching the main group. If I can find my targets I will take a few pics and post. It is essentially blowing out a group that should be in the .1s or low .2s into the .3's and .4's
