taffy Posted August 19, 2016 Report Share Posted August 19, 2016 Just had my new AI AT back in 22BR. Been a while and have a 1:12 Krieger to shoot 53gr V-Max. Started with 31gr VV133 BR4 and seated 20 thou forward from the datum point. This is not necessarily jammed into the lands. Shot a vertical slot. It's been a while and I am returning albeit slowly to the fold. Can't bloody remember if this is a velocity syndrome or seating depth related. Could someone re educate me please?? Thanks......

The Gun Pimp Posted August 19, 2016 Report Share Posted August 19, 2016 'Vertical' simply means that the barrel is out of tune. Tweak the load 1/3 grain either way and you should get rid of it. The other cause of vertical is down to inconsistent gun-handling. Link to comment Share on other sites More sharing options...
AnthonyR Posted August 19, 2016 Report Share Posted August 19, 2016 Personally I would use the Sierra 55gr BK which I have found is a much more consistent bullet than the 53gr V-Max Link to comment Share on other sites More sharing options...
garyw Posted August 19, 2016 Report Share Posted August 19, 2016 use N135 with the br4 s that will make it sing. Link to comment Share on other sites More sharing options...

gunner Posted August 20, 2016 Report Share Posted August 20, 2016 Hi taff , if it were me id switch to sierra or another make bullet as stated , some of the boxes contain different bullets from different batches recently with Hornadys etc . I used to use 50 & 55 sbk in a 223 and 223ack both were very accurate bullets . Also just wondering how your brass is sized ? As too much neck tention can cause inconsistent results . Normally the problem would be solved by either expanding the necks with a mandril or using a bushing die of some sort to get the fit just right ! Pork has or had a br22 and from memory it was his most favourite caliber all the best .... Link to comment Share on other sites More sharing options...
garyw Posted August 20, 2016 Report Share Posted August 20, 2016 theres nothing wrong with vmaxs for vermin -bks are also very good but for me the vmax expands more. Link to comment Share on other sites More sharing options...
justin credible Posted August 20, 2016 Report Share Posted August 20, 2016 I stopped using vv133 and went over to RS52 in my 22br and shot the smallest 3 shot group that I have ever managed, a 0.045" Happy days. Link to comment Share on other sites More sharing options...
Vermincinerator Posted August 20, 2016 Report Share Posted August 20, 2016 I shoot 55grn BKs in my 22BR over 31grns of Vit 135, it drops five into .200 MOA @ 100yds and holds sub 1.5" groups at 500yds Ian. Link to comment Share on other sites More sharing options...
Shuggy Posted August 20, 2016 Report Share Posted August 20, 2016 @taffy Does your AI AT feed the BR cases, or do you just single feed? Link to comment Share on other sites More sharing options...
pork chop Posted August 21, 2016 Report Share Posted August 21, 2016 Loaded some 69 gr tmk under some 135 today,hopefully get out to try them tomorrow. Had the rifle three months or so now and not done anything with it yet Link to comment Share on other sites More sharing options...
Big Al Posted August 21, 2016 Report Share Posted August 21, 2016 N140 with 69 TMK's works well for mine and a friends rifle I built. He has had good results with N140 and 55 SBK's from a 9 twist. Link to comment Share on other sites More sharing options...
justin credible Posted August 22, 2016 Report Share Posted August 22, 2016 What length barrels are you people using? Link to comment Share on other sites More sharing options...
OSOK Posted August 22, 2016 Report Share Posted August 22, 2016 Horizontal strings is usually seating depth , My old 22BR load development shows the horizontal string and in my case it just needed the bullet seating a tad further out .
