Thread: Rifle Double Grouping

Took my brand new bush rifle to the NZDA range today to run it in and also sight it in.
It's a un-suppressed latte bubbler (Howa 1500 stainless hogue 7mm08). Came with a Nikko Sterling 3-9x40 scope.

Did the long run in method - shoot 1 clean 1 etc.
Then sighted it at 50m to reasonable groupings, or so I thought.

This following cluster fuck is mostly 3 shot groups and 10-15 mins at least between each grouping.......

Onto the 100m and it was all over the place. Couldn't get it to group at all. To be honest, I probably fired too many rounds chasing my tail at this point.

Got out my AR and checked I could at least shoot that OK. Let out some frustration with that.
Kinda felt sorry for the fella next to me though. He had brass pelting him for a couple of mag dumps. He was a GC though.

Went back to 50m and bore sighted the 7mm08. Then fired 3 shot groups to sight in. Seemed OK so onto the 100m.
Not even on the paper this time. WTF??? RO was spotting for me by now and couldn't understand what was happening as well.
Back to 50 and took my time to try and see what was up. Firing single shots and leaving it a few mins between shots.
He noticed that every 3rd shot grouped real nice and tight on the 1st shot. 2nd shot dropped approx 2" low and left and 4th shot grouped tight with 2nd.
Grouped nicely enough like that so went to the 100m again. Firing single shots leaving it a few mins between shots.
Did exactly the same grouping type there. 1st and 3rd almost in same spot, under 1". 2nd and 4th low and left (probably 4" gap) but grouped tight also.
Left it here after 60 rounds fired in total today.

Only explanation is recoil lug could need work to stop this double grouping.

Heard that this can be typical type fault of the Hogue stocks.
Anyone had any experience with them?

Thinking I will have to get the stock bedded, or fit another stock.
