short barrelled 308 bullet/powder

I recently bought a Ruger Gunsite Scout rifle in 308, mainly because it had a VX-6 Leupold 1-6x CDS scope on it. It's the newer version that's got the light synthetic stock, only weighs 6.2lbs. It has the XS sight systems long rail so the scope is mounted in the normal place, not out front. I also got a 3rd magazine with it that doesn't stick way out the bottom. I planned to re-sell the rifle but after shooting it a bit I found it was delivering 1.25-1.5" groups with cheaper Winchester or Hornady 150gr loads. I had the trigger worked over and shrank those to 1-1.25" groups consistently. I'm sure it's capable of better with more than a 6x scope or more ammo experimentation.

I have a mule deer hunt planned this fall where there is a lot of thick timber. Those I've talked to about the area recommend going into the thick stuff after the deer, doing a lot of still hunting to find those early October bucks that are holed up. I am thinking of taking this rifle along for that, as well as my 300WM. If normal glassing and spot and stalk hunting don't work, I might pack the short 308 for going in after them.

I'm thinking I will likely try to work up a load for the rifle before taking it, try to improve a bit on groups and go with a little more aerodynamic bullet. I'm thinking maybe like a 150gr Accubond. Shots in the timber might be rushed and angles might not be ideal so a tougher bullet might be a better choice. If I get a load worked up I'll chronograph it and have the CDS turret built to match it. If a 300-350yd shot does present itself I'd feel better dialing range with the limited velocity the short barrel will provide.

Anyone have any recommendations on what bullet or powder I should try for this experiment? Or even if I should try, or just stick with the 24" barreled 300WM and use it everywhere? It has a 3.5-18x Swaro so the field of view isn't bad on the bottom end.

Thanks for the advice.

I use a model 70 classic compact in 7mm08. Very similar sized gun, short barrel. SHoots well out to 400, contrary to popular belief that a short barrel gun is only good for short range. My favorite load that i have found is 140 grain Hornady Superformance. I have killed dozens of whitetails in northern wisconsin 160-220 pounds and several mule deer bucks in Wyoming with it. This combination for whatever reason, "drops them in their tracks".

The theory around a short barrel being only good for short range came from using open sights. The longer the barrel the longer the sight radius was so the longer barrel equaled longer range. To take it to a extreme look at a pistol with a 4" barrel compared to a rifle of the same clambering with a 18" barrel.

As for switching between rifles, that is up to you. What is going to happen if you break into a open area and spot the buck of a lifetime at 500 yards and you have the .308? Run back to camp and get the .300? I personally would stick with one rifle and not look back, either the .308 or the 300 will do just fine in either situation except I would give the edge to the .300 with the higher magnification scope on it for a longer shot, but that Leupold cranked up to 6x should do the job.

You will also find that mule deer are not hard to kill, now if you were talking of mule deer and elk I would say to leave the .308 at home and take the .300.

Thanks everyone. I can shoot either pretty well, but have owned the 300 longer and used it successfully last season on my muley. It will be my primary gun for sure at least until we decide we won't see deer moving on their own and have to go in looking for them. Then we will see. If nothing else it will give me an excuse to get the 308 shot some more.

I know short barrels aren't inaccurate, they are stiffer than a longer barrel of the same contour and often more accurate. Velocity is where they lose ground to the longer barrel.

Thanks the replies give me a place to start on powder. I'll get some Nosler brass coming and I already have some 150gr Accubonds to start with. Past that we will see where it leads us.

More hours on Google Earth tonight and some other ciphering make me think the 300 will be getting the job. I trust the 180gr AB for poor shot angles, and practiced with that rifle a lot last fall out to 600yds. I trust it. It's not ideal for a lot of things, I'd rather have my heavier 264 for really long shots or my short 308 for close fast shots, but it is versatile. Great rifle for handling a wide variety of unforeseen situations which is how my western hunts usually play out.

Maybe I just suck at stalking but I did some math tonight. Looking at my journals my average shot distance on my 7 mature, trophy to me, western game animals (2 antelope, 2 elk, 3 muleys) is 301yds. I honestly don't try to get closer than 300yds most times. If I can get a great rest inside that range I'm taking the shot unless wind or angle are terrible. I was a little shocked at this. I knew my elk were long shots but it seems most mature animals live in country where you can't see them from that far away. As I (hopefully) add more deer to my total I bet the distance will shrink. My buddy I hunt with has an average shot distance of 198yds and we have been side by side on all but one of his 6 animals, just luck of the draw on whose day it has been to shoot first. My closest shot was 175yds and his was 30yds.

Anyway looking at my history I think I'll risk having the 300 cost me a close shot rather than chance missing an average one I'd have made with the 300. Not broke don't fix it I guess.

Thanks everyone for the help.

4895 is a great powder, I use it in my 30-06. The reason I suggested 3031 is because it is a little faster burning than 4895 and it might work well in the shorter barrel.

for powder used 4895, bullet I would keep it in the 150-155 grain. If you think longest you will be shooting is 350, bullet BC doesn't matter. Well it won't make a noticeable difference. So pick a good hunting bullet and if the rifle likes it your golden.

44 grains of RL-15 topped with a 165 Sierra gameking is getting me sub moa. Chronoed at 2565 fps out of my Ruger American predator with 18" barrel.
