Thread: .308 bush pig load workup

My bush pig is an Interarms Mark X with a .308. barrel cut to 16”. I think. It has a Gunworks suppressor.
My initial load was a 125 accubond with H335 powder. I used H335 because I had it left over from my 7/08 bush pig.
I wanted to work up a 150gr projectile load because it would hold energy further than the 125 and I wanted to use a cheaper projectile.
I couldn’t find any 2206H or 2208 so bought some more H335 and worked with that. The projectile I could find was a 150gr Hornady SP.
I loaded single rounds with 41, 42, 43, 44 and 45 gr H335, Federal large rifle primer
I shot them over the chrono 41 gave 2267fps, 42 gave 2280 43- didn’t shoot because I bulged the shoulder seating the projectile, 44 gave 2478, 45 gave 2539.
None of the loads showed pressure signs.
I then loaded 3@45gr and 3@45.5gr.
I shot the 45gr first at 100yd. Group size was around 2”. Then shot the 45.5gr and got a 0.879” group


The awesome thing was it is 2.5” high and 1” right of the 125 accubond 1” zero. So I loaded another 3 of the 45.5gr load, moved the scope 3 clicks left and shot a 0.839” group. Final average velocity is 2560fps.


The 3 shots around the group are from the 45gr load.
So new load worked and sighted in with 14 rounds.

Nice, keep an eye out for 2206H and grab a couple more hundred FPS

What brass were you using @stug? Sounds like a 168 ELD-M could go fast enough out of that to be effective way out as well?

Try CFE223 if you want some speed. I had 168gr ELD's hitting 2700 easy out of an 18" barrel, well below max too from memory

you have under inch load with cheap 150s...JOB DONE..... good man.

@Rated M for Magnum Winchester brass.

Good work. All hornday SP bullets are easy to work with.

Nice, that's an easy no fuss load, only asking because I'm interested in making something similar and always curious about the short barrel setups
