Badlands BD-2 load data

[MASH]

I did try the 135's but with my short action I was not able to load them long enough to make them worthwhile, had to jump them way too much the groupings were terrible. RL26 is the ticket if you want velocity, can't remember exactly what speeds I was seeing at max but they were in the 31-3200 fps range.

Well I did a ladder test and made it to 59.0grns @ 3216fps. 59.5 I had heavy bolt lift and ejector marks on the case head. This is with 4831SC loaded to 2.320CBTO.

Well….it was -1° when I got to the range. Needless to say I didn't shoot all the rounds I had brought.

375 EnABELR
30" K and P 1:8 twist barrel
390 grain Super Bulldozer-2
Powder: Retumbo
Primer: REM 9 1/2M
Cartridge: Virgin Peterson

No signs of pressure on any of the loads. Not sure how fast I'll try and push it. I was shooting for 2850 with the 125gn's and exceeded that.

On a side note, my scope is bottomed out and still shooting a foot low at 300 yards. I have a 60 MOA rail on it now, might have to throw the 40 MOA rail on.

Charge - Speed
120gn - 2817
120gn - 2792
120gn - 2796
120gn - 2825
123gn - 2904
124gn - 2902
125.5gn - 2948

Loading 175gr SB-2 in 300wm Bergara B14 1:10 twist 24" Barrel.
I have: H4350,H1000, Retumbo, Varget, 4831SC Does anyone have any experience with similar combo?

A Little background, trying to find a load for a friend and he wanted Barnes TTSX or Berger(sorry NRAlifer), had good not great SD'S and ES but couldn't get it to group better than 1.25 MOA, did powder and seating ladders for both bullets with H1000 and 4831SC. Thinking about trying both powder charges with the SB2's. Thoughts?

I've run the 195's in my 300WM and 300PRC. I'll have to dig through my data. Badlands will pressure up faster than the Barnes of similar weight.

I ran H1000 in my 300WM and found a really good load with N570 in my PRC.

Also, glad this thread resurfaced. I'm loath to look at every page of the thread. Anyone try the 136grn .308 in a 308 win?

I've been reworking my 338NM load with the 275's since I put a new barrel on. Trying to get it a little faster. Going to have to try a new powder. It seems the faster I'm getting the bigger the groups are getting. Not acceptable. Going to pull the barrel off and check my COAL again touching the lands.

Speeds chrono'ed with a Garmin Xero C1.

You shooting the 195's? Thinking about a fast twist 30 cal to shoot the 205's.

Yes Sir 195's

Seeing the speeds I was looking for with the 275 SBD-2 in my 338NM.

Not sure how much of a difference it really makes, but this is a CIP cut chamber.

Case: Peterson Fired
Barrel: 26" 1:8 K & P - 6 groove
Powder: H1000
Primer: CCI #34
Bullet: 275 SBD-2 - Seated at mag length. 2.760" to OGIVE. Roughly .100" of jump.

Charge - Speed (3 shots per charge)
90.5 - 2869, 2858, 2884
90.8 - 2874, 2871, 2875
91.1 - 2878, 2870, 2875

I need to try a faster powder with the 365's. 24N41 fills it up pretty good, and I have to seat the bullets pretty far into the case to be just off the lands.

Case: Virgin Peterson

2.897" to Ogive 132.2 - 2855, 2874, 2876

Going to drop down to 90.35gn of H1000 and see if I can get the groups to tighten back up like they were at a lower speed.

I have a 8 Twist 270WSM on the way which is being built on a Long Action with .200 Freebore. Looking forward to running the 140 and 150's in it.

Done. Range time will be in 2 weeks. Just got this finished up yesterday.
