Badlands BD-2 load data

Well did some testing today for seating depth. From Mag length all the way to .020 off the lands. Nothing to horrible actually so need to pick one and start working up powder charge. No speeds yet, using H4350, Lapua brass.
What charge were you using from first to last, can't figure out what you wrote on the targets.? I love the H 4350 and use it in my 308 and 7X08 and 6.5 PRC. So goo all around,

That was at 37grns. I did get back out again just got caught up with some deer hunts and family over the holidays. I was able to get 44grns into the case with it seated 80 thou off the lands which gives me a 2.162 BTO. That resulted in 2850fps on the magneto speed. Not bad for 18" barrel and running suppressed. I saved the rest to try in my 6.5x284N. I'll start another post for that one next.
 
Played with the 135 SBD2's in my 6.5/284 yesterday at the range. Rem700 long action, Proof 1:7.5 twist 26". I can seat these pretty long and they still fit in the BDL style bottom metal. Seated them @ 2.851 BTO and tried them with I4831, H4831SC, H4350, and N565. The 4831 and the 4831SC were very close to one another the SC being slower. The H4350 produced the best speed and did not hit pressure up to 50.0grns. Looks like I can get about 54–55 grns in the case up to the shoulder and that is where the bullet is seated. Results are:
I4831. / H4831SC
45.0grn - 2534. / 2528
46.0. - 2541
47.0. - 2647
49.0. - 2765 / 50.0 - 2740
No pressure can go higher
H4350
46.0 - 2767
47.0. - 2804
48.0 - 2867
49.0 - 2936
50.0 - 3004 no pressure can go higher

N565 started very slow, I don't think I can get enough in the case to get the speed I'm looking for. Only shot three out of the ladder to save powder and bullets.
46.0 - 2468fps
48.0. - 2707
51.0 - 2730

I would to get these to 3100fps as long as the accuracy is good. The N565 around the 2700fps mark was producing one hole groups. This was only at 100yds. The high power range was closed for a Cowboy match, which is normally where I shoot and can go out to 560yds. Just ordered 150 more and and looking forward to stretching them out and fine tuning to get them dialed in.

These 390 grain bulldozers should work well. 😬

Left to right: 195 grain 300 PRC, 275 grain 338NM, 390 grain 375 EnABELR.

Action and reamer are ordered, barrel is in the office with a second on the way shortly.

Hopefully I'm getting a load developed by the fall, in time for some mountain top fun.

Those are mighty sexy! 🤣 I am curious about the velocities from a 24" with the 275 out of my .338 NMI. Thanks!

My hunting load is right around 2850fps out of my 26" barrel. Need to go shoot my rifle with the can next month and see if there is any POI shift.

This is that 800 yard group with the 275's from two hunting seasons ago.
