Hi all. Anyone have loads worked up for 7ss for 150gr Badlands bulldozer, 168gr berger vld hunting, or 168gr nosler long range accubond? Or suggestions on starting point for those projectiles? (Everything I am seeing in the load data in this thread starts with heavier bullets.) Thanks!
Give me 2 weeks. I’m fixing to start testing loads on the 150 bulldozers and 168 Berger’s

I haven’t gotten a chance to test the 150’s yet but I did an OWC test with 168’s and finished around 62.7 grains of RL26 @ 2850. I’m shooting a 20” barrel though so I was pretty happy with these numbers. I ran it up to 63.4 but that was way to hot

Excellent! Thanks for the input. I am at 23”, so i might get a few more fps out of it. Will be interested to hear once you play with the 150s too.

I decided to check out the absolute hammers.

With the 119grain AHs
Using IMR4166 at 60 grains I got a shiny spot from the ejector on my 7mm ss brass.

Velocity 3719fps

This weekend I'll be testing out the absolute hammer 172grain with IMR4166. I tried it already with 66 grains of vv n170. Got 2960fps. It was a compressed load with zero indication of pressure.

This is with a 30 inch barrel

Wisc- What powder load did you use for this load? I will be loading up the 169 HH with some H4831 and H4350 this weekend.

Sorry ....57grs H4350

Hit pressure at 58 and was in a hurry so dropped a grain and flew to Alaska. All shots from 54-58 grs were in about 3/4 string left to right by about a 1/8 high while not at all shooting for groups but rather fast fire.

Once in Alaska, I got another chance to shoot for groups....one ragged hole (just over one bullet hole size) WITHOUT excessive focus (Grip pressure, shoulder pressure, bipod load, eyebox, parallax, etc). Stark contrast to the Hornady ELDM 180's which I really have to work hard on my form to get a cloverleaf (often with fliers).

Shot the Hammer Hunters later in the trip up a mountain valley (15* incline). Needed 4.6mil elevation at 763yrds and 13.1mils at 1273yrds on rock faces, accuracy remained excellent. Bullet impacts splash marks were just slightly separated at 763. Very tight and predictable at 1273 as well but don't remember the size if the rock face. Ran out of the Hammers by the time we were shooting at 1830yrds so only used the ELDM's there and we kept most of them in a .5mil group at that distance. Overall, blown away by the Hammers (ease of loading, super consistent groups...) just the BC was much lower than expected. Hammers says .274G7 for the 155 Hammer Hunter but I used .221 in Trasol with truing the drag curve to .355. Downloaded AB when I got back which says .206 G7. Trasol was the same data in .206 with the default .500 Drag. Trasol's data (4.73/13.11) lined up with my real world dope (4.6/13.1) where AB (4.5/11.8) and BallisticsARC (4.5/12.1)where both considerably off.

Really want to get more of the 155’s Hunters, 155 Absolutes and 172 Absolute Hammers and spend some more tome at distance. Considering the Badlands but the Hammers were so impressive I am reluctant to move away from them.

I just got done with the first check on the 172 absolute hammers using IMR4166

51 grains had no sign of pressure at all at 2940 fps
52 grains had very slight ejector mark at 3018fps

There was still a large amount of empty space in the case really need to try a powder probably half way between 4166 and n170 to get the best out of this one but I suspect that it will likely top out somewhere under 3100 at best since the 4166 gave 57 fps faster than the n170.

Parts unknown....
Been a longtime in the make but here is my data from today:

7SS 26"
Proof Sendero 1:8.44
Area419 Hellfire

7SS Fireform load: ADG brass. Sierra 175 Match King HPBT over 54gn Rl26 jammed very lightly - 2600FPS. very crisp shoulders and very tight groups.

7SS
ADG brass
175 Berger Elite Hunter
62.5gn RL26 @ 3030FPS
Federal 210M
2.227 BTO

Note: Zero pressure sign, very accurate. Going to be my hunting load this season since I am short on time/range time

Will try the 180VLD and 195EOLs next go round.
