OCW day 2 testing Varget and 185 Berger Juggernaughts seating depth testing.

[diego-ted]

Went back out to do seating depth testing using the 44.5 gr of Varget load recommended by Eric. This was shot out doors as opposed to yesterday’s test which was indoors. The wind was pretty switchy today right to left and the results show this. The specs are Savage FT/R rifle that has been pillar bedded with the action and bolt trued. The barrel is a 30” Krieger. The load is Varget and 185 Juggernauts.

Here is yesterday’s target.



And heres todays. The shoot and Cs are yeasterdays best groups of 44 and 45 grs of Varget the blue circle is a pulled shot. The other shoot and C is my foulers which is FGMM 168 around 15 rounds!



What do you guys think?

thx Ted

I like the .020" off the lands one.

 

[JGorski]

.005" off the lands is what I like. You want that low vertical.

 

[RyeDaddy]

I agree with Gorski, I'd go with 0.005" off. I'd like to know what it looks like indoors with no wind.

I am probably wrong, but I interpret your OCW to be closer to 43.5 than 44.5. and the .015 looks about right to me as your best poi average centering up those groups. I am still an OCW novice and would love to hear Mr Newberry's opinion.

If we're looking at a scatter node at 42.5, then it should follow that about 43.1 grains would be an OCW. And the next node after that would be at 44.4 grains.

I'd probably go with 43.1 grains and work on the seating depth to get the best accuracy and tightest extreme spread. The OAL test done at the higher charge weight will not likely apply to the 43.1 grain charge.
