Any question? Toss 'em.
The bottom two looks like those defects are in the brass, not likely to be a problem. The split is easy. A split on a 1x is pretty rare unless it is very old.
I'd still toss 'em.
I'm working up a series of loads for my 6.5-300 Weatherby. One of my bullet choices in the 127 LRX, which should be good choice. I was reading Brian Pearce's article in Handloader on the caliber and he shows a COAL for the 127 LRX at 3.50", while Hodgdon lists 3.59" and Barnes lists 3.58". None...
Elk/Deer in Montana: Blaser R8 in 300 Weatherby with 180 grain TTSX's.
Antelope: Blaser R8 in 6.5-300 Weatherby with 127 grain LRX
Blacktail on Kodiak Island: Blaser R8 in 375 H&H with 270 grain CEB Safari Raptor (A little extra firepower in case of an uninvited Ursus arctos ssp.)
If the 7-08 kicks too much with a muzzle brake there's little you can do except possibly add a recoil pad to the clothing (more mimicking hunting clothing) and adding weight to the rifle.
Since Elk is on the menu, you wouldn't want to lighten the load too much.
I'm thinking seriously of ending my annual trip to MT for deer/elk. It's $1055 now, plus antelope if I draw. I may have to find out where Mr. Miner has some hunting grounds because WA access has been an issue for me, which is why I started going to MT.
For the cost of an outfitted hunt in MT...
I use the 168 TTSX's in my 30 caliber rifles for just about anything that walks. They do want a little more jump for best accuracy. In the 300 Weatherby I can put 8 shots in .4", and the 30-06 is pretty close.
According to the date on your target analysis, this load is from the future ... that is another special capability of the Weatherby calibers.
I exclusively use 7828SSC in my Weatherby calibers with similar results to you. I will be tuning up a 6.5-300 soon and I will try it there, too.
300 Weatherby, 168 grain TTSX. Wind is swirling, so, I'll decide at the last moment but likely ignore. I'd follow a line up from between the front legs, 1/3 to 1/4 up and prepare to field dress.
I use 55 in-lbs as advised by the factory some time ago.
I found a .010" seating depth change to be quite effective in the .257. I personally use only IMR 7828SSC in all Weatherby calibers but RL-22 should be fine.
There are some corner cases where the 180 won't stabilize, but, they may or may not apply to you.
I use the 180 Barnes TTSX in a 1:11 twist and a full load of IMR 7828SSC to great effect. I use the same powder of the 168, too.
I use that process on certain calibers and get far straighter (and more consistent) necks than I do with the expander ball.
I don't use my Dillon, though, but my Redding turret.
I load 4451 for the 30-06 with 180 AB's and CCI primers. Very effective. I also have some 168 TTSX loads developed but they haven't been used on game yet.
While you get very little copper, the stuff is quite dirty unless you run it at the top accuracy node rather than the slower one in the data.
