Got any pics of the rifle?

I'll have to take some. The barreled action is gorgeous, but I put it in a tupperware stock (temporary), so it looks like crap. The secret is the barrel, which is a Douglas Match Grade "Reject". It is a reject due to a slight taper in the bore, which Rob used to our advantage. He put the taper towards the muzzle, giving a tighter grip on the projectile the whole way down the tube.

I shot this 5 shot group today with 53 gr, imr 4350 and the 310 Thumper..794" @ 100 yds.
The shot to the right and slightly high of the group was part of a vertical string from another load.

Ok , i don't know how i managed to get the lines through the type in my last post.
Anyway, i didn't chrono because previous loads of 50 and 52 gr. of 4350 gave me vertical stringing and i didn't want to take a chance on shooting the chrony.

54 gr. with a 280 gave me a bit over 2200 fps. so i'm guessing 2100 fps. plus with the 310 @ 53 gr. I'll chrono this load next time. The powder burned very cleanly at 53 gr., so it could easily be 2200 fps....we'll see.

54 gr. opened up again with vertical stringing. I think this bullet is giving my break action Encore all it wants lol. If the load isn't just right it's all about vertical strings so far with this bullet in my single shot.

I've got a few left, so i'll try 52 1/2. 53(again), and 53 1/2 gr. next time. I was using 3 coats of BLL.
I may try 55 gr. also, but not much room for more powder past the 54 gr. load, so i doubt it will "come back in" past 54 gr.

Interestingly, my aa 4350 powder data shows 55 gr. under a 358009(280 gr. bullet) as max, but not compressed for 2203 fps. and 41,600 psi.
I will say again this bullet wound up being very well designed to allow the same amount of powder to be loaded under it as i see you already loaded 55 gr. of imr under yours yodog.

Loaded up the next progression - 51.0 to 55.0 grains of WC852f, in 1 grain increments. Groups were not horrible, but I did get some fliers...those might be all me though. In my haste to get loaded up for the weekend trip to the range, I failed to sort the Thumpers by weight (which I did on the prior test). I also switched my lube to 2500+. In retrospect, that might have been a mistake, since I am nowhere near 2500 fps. I will do some more testing, comparing the two lubes.

51.0 had potential, but there was a first round flier from the cold bore, and one additional flier that ruined the group. 3 shots in one hole though. 52.0 was the same. Wish I had weighed all the bullets.

53.0 - pretty happy with this one, as once again, there are 3 rounds in one ragged hole.

55.0 - although this isn't the best group, it certainly is sufficient...and a real thumper. This one hurts on the back end too. I won't be trying anything beyond this - I don't think it is necessary.

The uppermost holes are from the 53.0 group above. Looks like there is quite a bit of lube fouling on the holes - thinking the 2500+ might be too much of a good thing. Still have some lubed with Javelina that I am going to test again.

Made another trip to the range to test out the two best loads from my last outing (53.0 and 55.0 WC852f). The bullets were the same WW + 2%, water dropped, aged for several weeks and this time lubed with 50/50 and a single coat of BLL. I was careful to weight sort the bullets to insure I didn't have any fliers due to my carelessness (again). The first group with 53.0 was nowhere near where I thought it should be, so I did not pull the targets or take pics. 55.0, on the other hand, was spectacular. I had 4 shots that measured 0.804, center to center. The 5th shot (4th of the string) went way high, and I believe it was all me. It was raining a bit, and the tupperware stock got a bit slippery...when I touched off the round, the recoil ripped the forearm right out of my hand and I believe this caused the round to strike high. The last shot went right in the middle of the group, due to me hanging on this time. I think I have found my load - I plan on testing the lubes, head to head, one last time and will pick a winner for my hunting load.

Very nice 5shot. I well know about rainy days and plastic stocks. I used to have a 7/08 in a synthetic stock that the forearm would fly out of my hand when wet.

I wasted my time shooting the wrong seating depth today(3.220" instead of 3.200")....rookie mistake for sure.
Same load that gave a .794" the other day was more like 6" today.

Oh well, good excuse to load some more(at the right seating depth) and back to the range to make sure that tight group wasn't a fluke the other day.

Well, the dummy found his dummy round tonight....yep 3.200 on the nose.
It is written down correctly in the load notes now.....haven't made a mistake like that in years, but that's why i keep dummy rounds for every bullet.

I always thought they were called dummy rounds because of no primer in the case, but now the term has a whole new meaning to me.

Got ten more loaded tonight with 53 gr. of imr 4350 along with some 200 gr. pb
with unique to try in the morning.

Ok, after shooting 2 more 5 shot groups @ 53 gr. of imr 4350 with the 310 Thumper bullet and continueing to get 4 to 6" vertical strings...i have to say i made a mistake when i posted the .794" target the other day.

I also shot my noe 360230 bullet the same day and must have gotten the groups mixed up.
Sooooo, i'm still working with the 310 gr. and imr 4350 is not looking so good with it.

Very sorry for the confusion Yodogsandman.
Both you and 5shot are doing much better than me with it.

Again, very sorry for what had to be a mistake on my part!!
