Help with light weight .338RUM build

I am looking for advice on building .338RUM with mimimum weight. I plan to shoot the 250 grain Berger bullets when they are released. Do you think that a 1 : 10 twist will stabilise them? What would be better?

What would be the shortest barrel length practical without excessive velocity loss.

What would be the thinest barrel profife without substantial accuracy loss on three shot groups.

Action, thinking Remington 700 to keep cost down but have access to Lawton actions also.

With a scope weight limit of about 20oz, what scope would you use? Thinking Bushnell Elite 6500 in 2.5 - 16 x 42.

Mounts, need to be reliable and strong but light.

Stock, thinking of Manners T4 but not sure?

Brake, needs to be a good one.

Any help and advice would be great.

Re: Help with light weight .338RUM build

I have a Defensive Edge Stalker in 338rum.
HS precision pro series stock
Rem 700 action
Hart #5 26" fluted barrel - 1 in 10
DE brake - makes the gun very comfortable to shoot
The gun weighs around 8.5#'s
It wears a Nightforce 2.5x10x32 scope
The gun is a tack driver.
I am shooting the Barnes 225 grain ttsx bullets - H1000 powder and CCI 250mag primers

My buddy shoots a Savage weather warrior 338 win he has the Bushnel 6500 elite on it. He really likes the scope. They have a pretty good discount program if you are a firearm safety instructor.

Robbin,
I am talking light weight by RUM standards. I would say the rifle all up with scope is going to be about 9lb.

I have a 9lb .458WM that I shoot prone off a Bipod without a brake so am not worried about recoil.

With a good brake the .338RUM will be a pussy to shoot.

Re: Help with light weight .338RUM build

You are tougher than I am, that's all there is too it. My step son has a stock Rem 300RUM. It's no fun too shoot on a bench or prone. He put a break on it, it's still no FUN to shoot, but it doesn't HURT now.

I would love to get a 338 for the long range performance it has, but I enjoy shooting, and I don't think I would enjoy shooting that.

Good luck, don't forget to update us on your build.
Robbin

Re: Help with light weight .338RUM build

A 300 win mag is about the most recoil I can tolorate and still shoot well for an extended period of time in an un-braked gun. That being said my 338rum from Defensive Edge with their brake is a pleasure to shoot. The recoil is about the same push as a 308 - I say push because there is no sharp crack.

I have shot un-braked 300rums on several occasions and can tell you that after a few rounds they are no fun to shoot.

Robbin - I would recommend that your step son get a different brake for his gun. I have had good luck with the Defensive Edge brake and the brake that Jim at Center Shot Rifles makes.

The Remington action is a good choice because of all the after market parts that are available.

The barrel contour I would recomend would be a #4 or fluted #5 Lilja 22 or 23" long (The brake
will add 1.5+" to the overall length).

I would use the Holland Quick Discharge break because it is very effective and light weight.
(The Round one).

Composites stocks are all about the same weight so it is just a matter of what you like.

For the scope I would look at a Leupold because of the weight and most important Leupold
has the most eye relief and with a light rifle you will need all you can get for shooting out
of position (Hunting situations hardly ever have perfect shooting positions).

Also I would recomend the use of bullets that weight 210 to 225 grains for best performance
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.
