.308 load for short barrel

Hi guys, me again. I got a few sets of reloading dies while in Wisconsin on business (man, they got everything there!) I'm looking for a load recipe for a .308 Remington Mohawk 600 bolt gun. It's got a short barrel, 18" I think. These guns were known for muzzle blast because of the short barrel and the factory ammo available. I'd like to work up a good load for elk. For elk I would normally prefer a heavy-for-caliber bullet (high SD). I don't want to give up velocity if I don't have to. Heavy bullets normally need slower powder, correct? Slower powder in a short barrel won't be very efficient, right? Does the short barrel make heavier bullets a less attractive combination or is there a way around it? I suspect I'll have to compromise on something here. What do you guys think?

.308 load for short barrel

IMR 3031, 41.0 gr with 180 grainers and

IMR 4350 50.0 gr with 180 grainers.

The 4350 gives you slightly higher energy(less than 100 ft/lbs than the 3031. I loaded both for my buddies 600Mohawk for decades with nothing but excellent results.
And you are right about the muzzle blast too Yes Thumbs up

You're right by saying the shorter the barrel <> the faster the powder for best results
Slower powders have(build up) more energy and you want that used within the barrel for max results. thus mag calibres are all 24 or 26 inch barrels for that reason(there could be the odd 22 " ones) but I can't think of any.

Thumbs up

.308 load for short barrel

With 180 gr bullets I always had good luck with 3031 also. plus WW748, H335 and BL/C #2. I didn't see a lot of difference in any of them and I think if was 3031 I eventually used, lost records in a house fire. I also dropped down to a 165 gr bullet.

loads

Thanks guys. I was thinking that, due to the shorter barrel, it might lead me to using 150g or 165g bullets and faster powder to get a complete burn, which should lead to less blast. Not that muzzle blast is a prime consideration, just seems like a waste of powder for no benefit. There are quite a few well constructed 150g and 165g bullets that would be fine for elk. I will try the 3031 once I accumulate enough spent brass to reload a batch. I've been taking the 600 out deer hunting but haven't seen anything worth shooting yet.

Try H-4895, IMR-4895 and Ramshot TAC. They work well in my 20" barrels.

4895

Thanks J,

What are you shooting for bullets weights with those powders?

150 and 165 grain bullets.

If you haven't already, try some flat base bullets. They sometimes shoot better at closer distances particularly from short barrels.

flat base

Good point. This isn't a bean field rifle. Pretty much nothing over 200 yds.
