Just starting load work in my 300wm with the 205 sbd2's. 28" 1:8 McGowan. H1000. Looking great so far. Hoping to put one in a bear this Sunday

Just a quick run through AB for the .284 160gn BD2 @ 3100 from my 26" 7Max @ sea level, has me seriously contemplating selling my 1:8 for a 1:7T barrel.
150's at 3150 aren't that far off and will run in a 1:8.5T. Little more versatile twist rate so may just stick with that.

Just about got my load figured out and then flyers like crazy. Ran the bore scope in and second half of barrel is copper fouled bad! Cleaning her up now. Hopefully that brings it right back to 1/2"@100
Here's my velocity test with H1000 in a 26" barrel, adg brass, tikka action cut with 225 freebore. Never found any pressure. Accuracy was horrible very few groups were under moa at 200y. My barrel is an 8tw. My seating depth obviously needs tuning, but nothing here showed any promise.

How many rounds fired before it fouled up?
.300 Dakota

Looks like a Hammer A-Tip. Had that poor Pronghorn doe of the OP killed and processed in hamburger and tenderized shoulder roast all in one shot!

Well, goat season has started, so more results!
.277 140 Super Bull Dozer, out of a 19" supressed .270 Sherman, final load was 3030 fps. This goat was taken at 275 yards. She was hit where you can see, and ran a death sprint as goats do, until she ran out of blood, about 75 yards. Good sized exit, blood sprayed all down her side.

Looks like it performs very well. Thanks 
This is very encouraging. I just bought some 175 Bulldozer 2s to run in a .308. Hopefully it will have enough horsepower to get good expansion from them.
Well, the caribou were both close. 150 and 100 yards. Dumped the first one where it stood and the second went about 5' and tipped over.
First shot on my moose was 880 yards and I made a bad wind call and hit him too far back on the lung. Adjusted and dumped him at 950 yards. He spun left and tipped over. Full penetration with the 275gn Super Bulldozer II's at 880 and 950.
Waited almost an hour before shooting the moose. Kept thinking he'd come closer as I called. He was more interested in finding another bull to fight. Closest he ever got was 875 yards. Luckily it was in the morning so we had plenty of time to clean him and get him back to camp before dark.
Can see the knob I was shooting off of in the picture with the skull and rifle. It's on the top left of the V notch.
Winter decided to come early and the temps dropped to 16° at night. Snowed all the way home from Fairbanks.

I don't have any kill info on the 275 sbd2 yet, but I did take them out to 1660m and put 3 consecutive on a 30 " plate at the range, then 2 more on a rock at about 1800m. I don't know how they grouped (couldn't drive out with other people still shooting at the range) but it seemed like they were nice and consistent.

Got a critter down with the .338 250 SBDII
Pronghorn doe at 595 yards, impact of 2338 fps. Entered between the humorous and scapula, missed any ribs. On exit it went the same place, missing the humorous and scapula, but centered up with a rib. Pictures explain the rest!
Entrance hair on
Exit hair on
Internal - right side of pic entrance, left exit. Note how the entrance side lung is damaged, but woukd still hold together in one piece when picked up, the exit side was jelly, and would fall apart in your hand. This tells me that was how far it took to really do heavy damage, which is about 3ish inches.

Exit with Entrance visible through it
After the hit, she stumbled about 15ish yards and piled up, dead in like 10 seconds, pretty quick.
