Re: Help with light weight .338RUM build

Hi mate,with the right profile i would go 27-30 inches,i am having a 6.5-284 built right now on a lawton 7500 single shot(2.2lbs) it is along the same lines you are after i went with a 30" fluted barrel with a taper much like a palma contour(5lbs),i haven't decided on a stock but im likely to go for the manners mcs-ta(3.4lbs with adj cp)or holland signature(approx 2lbs),the rem 700 action is lighter than the action i am using,leupold mk4's are fairly light scopes.The T4 may be a bit heavy for what you want.

in this type and weight of rifle.

This combination should weigh in arround 8 lbs fully dressed and ready to go but should be very manageable and recoil should not be an issue.

J E,
What sort of performance loss would you expect from a 22 or 23" barrel compared to say a 26" or 27" barrel in .338RUM? 8lbs sounds about right but could afford another 1 lb if it meant that I could get a bit longer barrel.

I like the idea of the 225 grain bullet. Some very good ones available. But I also like the 250 grain bullets also.

300R,

That outfit might go over 11 pounds with the longer barrel once I you fit a scope and mounts. Sort of looking of about 9 lbs max, as I already have a 14lb big gun in .338Edge.

The reason for a shorter barrel is the handling not the weight. you don't gain that much
weight by adding 2" to the small end of the barrel.

If you want a 26" barrel it will end up at an overall length of about 28" with the break.

If you drop to 24" from 26" you will loose 50 to 60 ft/sec and have a rifle that is arround 26"
in barrel length.

I like longer barrels if I'm going to shoot 300gr bullets @ max velocity but the rifles become
awkward in a carry rifle also the longer the barrel is in a light contour the worse the
harmonics become making the rifle more finicky to load development.

I recomend keeping light barrels under 26" and heavy barrels under 34" because of barrel whip
in large caliber cartriges (Magnums).

Re: Help with light weight .338RUM build

i have a light weight 338 Edge, with a new stock it will probably be around 8.5 lbs. i have a 28" finished barrel but the whole gun is less than 36" long. that's including a holland radial port brake. it's not bad at all to shoot recoil wise, now muzzle blast is a different story. it'll move your hair around a little. i can shoot the 225 ttsx over 3400, but my load is around 3250. it's a bullpup design that is the easiest packin and handling rifle i've ever seen. i can hunt everthing from groundhogs to elk with it and we'll say it's a great hunting gun that can be used for long range if necessary. shot my turkey at 850 last year. i'm getting one of the new Viper pst scopes for it that's under 20 oz. would be a great long range hunting scope for a carry gun in my opinion.
