Show your Tikka ten round groups

[Duh]

Here’s my tikka 22-250 1:8 factory barrel and two 10 round groups this morning. Both groups were shot fairly rapid with no breaks between.

Haven’t found too much data on this combo so here’s mine: staball was a charge weight of 37.8 grains and the Varget was 33 grains. Got no pressure so I’ll probably go up on both from there. Both shooting 73 eldm, 1x fired hornady brass, with a Winchester primer. Bullet was seated a the hornady recommendation of 2.940. Both produced average velocitys in the 3100 range. Slight crosswind of 8-10 mph.

The staball 6.5 group was first group and had a es of approximately 70fps.

The varget group had an ES in the lower 20’s and is definitely minute of kill, IMO. Also the bullet by itself in the bottom right of the varget group was 100% me pulling the shot. I’m still counting it as part of the group though.

I’m going to stick with Varget unless staball gets its shit together with a higher charge weight. That’s a 9mm round for scale

108 ELDM from a 17 inch factory T3x lite barrel with a AB Raptor 8 muffler. MV was 2826, but I had slight pressure signs (42 gr H4350). 41 gr of H4350 got me 2764 with no pressure signs. But, I only loaded 5, so no 10 round group. Edit: On second thought, the first 5 rounds had no pressure signs, it started raining and the second 5 got wet and all had slight ejector marks, so I think it was false pressure signs. End Edit


The group below is more reflective of my baseline shooting ability (prone, over a pack, with a contractor trash back laid out to keep the dust off).

45 gr of H4831sc (I labeled the group wrong as using the app to analyze this group was an afterthought as I new I would not be using the load due to velocity/pressure, ignore that), this got me 2721 fps and mild pressure signs.

I’ve never used the Hornady App, but is there something goofy here with the Group size value in MRAD’s? The inch value makes sense, but the conversion to MRADS looks like it thinks the inch measurement is at 450yards (ish).
Or I’m losing my mind… I suppose either possibility shouldn’t be ruled out haha

Every time I see good shooting short 6 creeds like this though, the urge to lighten my wallet again grows.

I think the MRAD conversion is goofy. 0.88 inch should com out to 0.22 MRAD. Distance to target is set at 100 yards.

I wonder if the MRADs is something like zero angle? When I switch the app over to MOA it is giving me 0.38 MOA.
