Can’t ask for much more than that! Where did you end up at on your charge weight?

I updated the above photo with some "words" lol.

Here's a couple other 5 shot groups after I got close with a handful of 3 shot groups. With the sweet one below. I just dropped a dot each 5 shots. So it either likes 10 off, or it likes heat.




It out agged a dang good 6mm today by a .070" margin on 3 targets.

On my 3 shot tuning 15 off went wide, so that's why I went where I did with my remaining 15 rounds. Next time out I'll see if 10 1/2 off will lose that damn spitter! Lol

I just hope I can do as good as Roy making them once I get my lessons in June! Good boy @Roy H lol.

With that much powder- thinking a “push-up” would be better suited, than a wonder...lol

Great work Tom !!!

Its awesome to see a .30 shooting like a 6mm. Looking forward to see it agg this year.

@tom is this set up for HG?

Yes, it's an lrb solid fill, with a 6 inch stainless front bolted/glued plate. Bat M, right, left,, drop port glued and screwed. 30" Krieger 10 twist 1.350 tapered to an inch, and Harrell brake. Normal rear bag and front rest, so it's less foreign to me than some heavy guns.

Thank you

I could not find a picture of that rifle. McMillan can make the LRB stock about 9 ponds. With a Bat M and heavy barrel they end up about 25 pounds +/-. I have been getting more requests for these. I think guys like the light gun ergonomics with the extra weight of the heavy gun.

Got a picture from ol' Roy, oh boy!

Here's pictures from the three shot groups that I tried. Sighted OFF my dots, I can see what's what in my spotter. I would still like to see some at various settings into the rifling, and maybe see just how much past 10 off I can go before it widens out like the 15 off one. I was a little surprised about the 59.38 charge speeding up 75 fps more than I expected??? But it shot reasonably everywhere I tried, so it couldn't have been to unhappy.



Going to see about finding a lower node at 10 off, and then revisit the seating a bit more......see if I can get this thing worthy of competition lol!

Found an older picture...Nice and ugly, that way she has to work harder to stay around!



I've switched to my fulgham front rest since this was taken, but still shooting off my portable bench I bought (took) from Alex. The tire chains are the key, maybe I can hang them off the benches at DeepCreek!!!

Went and located the lower node today while seated at 10 off. It was miserable to see with the snow, but I believe I've got what I needed. After a little vacation I will pick it up here at about 58 1/4. Time for @GlennK to get busy, I'm going south for the rest of February lol.

Well, I guess the rest of us in Montana will just have to get out our warm jammies!

@tom @Alex Wheeler sizing questions

i Am assume alex made a FL die for this cartridge from JGS, how much are you sizing the base and shoulder OD? .003 ? Have you tried other amounts to see accuracy differences?
