Feel free to vote in the poll, and if you have any real world experience with the specific choices below in 7mm-08, please chime in with performance data.

Purpose. My buddy is a STAUNCH "ethical" hunter :rolleyes:. I don't judge him at all, as up until we started shooting together recently, he was a sight in at 100 and go hunt (10 rounds a year) shooter. He's killed a pile of deer, but his current max range kill is 185 yds. He's hoping to reach out further with me as a mentor, but still has a long way to go. I admire that he knows his limits and will absolutely stay within them. Down the road things may change, but for now, the following are hard limits. He wants "more than enough", not "in perfect conditions".

Elk (300 yds), Deer (400 yds), Moose (300 yds). 2200 fps impact velocity, 1400 ftlbs for deer, 1700 ft lbs for elk/moose.

Target shooting for giggles and training (400-750 yds mostly, 1000 yds max).

Rifle.

7mm-08, 24", 1:8 twist, 5R, X-Caliber Savage Prefit. ~1 MOA precision with him on the gun.

Available powders. (Unlikely to use anything else. This is for a friend's hunting rifle, and neither he nor I want to deal with the trouble/money of buying stuff to try for relatively small batch reloading).

6.5 Staball (First choice. Initial testing shows good speed, good reports of temp stability)
CFE 223 (a little too temp unstable for my taste)
Varget (Edited to add. Forgot I have a good stash of it. Might be just the ticket)
H4350 (likely too slow/bulky for this cartridge, but I have it on hand)
IMR4064 (at little too temp unstable for my taste)

Reloading philosophy.

Neither of us wanna spend a pile of money with different bullets/powders/primers. We're looking for the "easy button". I also don't want to hand him anything at the very upper end of pressures. I have about 60 pieces of Hornady brass for him, and if I could get 5-10 more reloads (annealing) on them, that would last him for years (one reload per year probably).

Also, I enjoy helping him, but I'm not willing to go down a rabbit hole trying to find some miracle load, and I don't think he has the patience for that either.

Sooo....

Which would you recommend?

130 AH

131 HH

140 AH

143 HH

I think we may struggle to get the speed we want with the AH due to the limited powder choices. I hear they like fast burners to get the extra speed they claim to offer. I also think the 130 class will struggle to deliver the energy he requires for the bigger ungulates. I'm inclined to just go with the 143 HH, but I don't really know what real world expectations are.

Also, we already tried the Badlands 140 SBDII, and it shoots like crap (1.5-2.5 MOA with several recipes) in his rifle (great in my 1:8 7mm Rem Mag. Go figure). Also tried Barnes 145 LRX (1 MOA), which will be the fallback if the Hammers don't work.

Thanks in advance.

Edited to add Varget to my list of powders.

I can't add much as far as a bullet choice but I can add this. My buddy is working with a new rifle and he's been getting 2950-3000' using both 6.5 staball and reloder 16 with a 140 berger. I'm shooting a 6.5 saum with a 140 accubond around 3000'. He burns 45 grains, I burn 60 grains of h1000. Bc on both bullets are almost equal. 7mm08 is a nice efficient choice for deer through elk. Best wishes to you both.
 
Used the 143g HH out of a .280 AI (3226 fps) this past Dec. on a cow elk. Bang flop.
Haven't killed anything yet with the wife's 7-08 Tikka T3 (stock factory) & HH but have shot it quite a bit for load development for different Hammer bullets.

Per your limitations and my Strelok Pro app:
131g HH will top out at 275yd. for elk: (2412 fps/ 1718 ft. lbs)
Deer gets to 400yds. (2167 fps/1388 ft.lbs.)
Not sure a deer will know/feel the 33fps/12 ft.lbs. difference....

143g HH gets to 300 yds. for elk: (2321 fps/ 1712 fps.)
Deer gets to: 350 yds. (2231 fps/1581)
NOTE: at 400 yds. 2145 fps/1461ft. lbs.
YMVMV. Good luck and you are, IMO, a very good friend to help your bud out.
 
Very helpful @Weaselthis .

I actually have a decent stash of Varget, which might be just the ticket for the AH options, and worth a try for "normal" 140 class bullets.

Also forgot to mention that we're limited in COAL. The X-caliber (and the Savage) is limited to right around 2.80" for magazine and lands. May be why the 140 SBDII did so poorly (it's WAAAY long at 1.44"). At 2.78" COAL for 30 thousands off lands, there's about a foot of bullet down in the case.
 
This is what I shoot in a CA Ridgeline 7-08. Powder is Varget 45.1, Lapua Brass, Hammer Hunter 120 grain. 3150 FPS. Could get more speed but hit serious accuracy node there. Longest kill is 485 on deer. Using Leupold VX5HD 3-15x44 CL2 firedot reticle. unless you're after moose and Elk on regular basis this is a killer.
 
I vote for the 140 AH. This season I worked up a load with it for elk hunting with my 40 yr old Ruger M77 7mm-08. (22 inch barrel, 1-10 twist) I'm getting 2900 FPS and good accuracy with 41.6 grains of Varget which should be good out to 300 yds plus for elk. Probably could get 3000 FPS or a bit more with the 130 AH, but the ballistics are still better with the 140 AH at 2900 FPS. Distance to lands is not applicable with the AH, so run your COAL out to what will comfortably fit and feed in you magazine. BTW, what did you settle on? Cheers
