You need a really heavy stock to balance a heavier barrel.
The barrel length plays into this as well as the stock weight and stock CG.
There's no single right answer as all the parts depend on each other.

A 20" M24 or M40 barrel balances significantly different than a 26" M24 or M40 barrel given the same stock.

A 26" Rem Varmint or Medium Palma might balance really similar to a 20" M24 or M40 though.
Randall, from your experience, how much does overall balance play into larger builds that will always be shot prone or from bench. Reason I'm asking is I'm starting a build in either 338 Lapua or 300 Norma. Initial thought is that to help maintain site picture and also my degrading shoulder, contours such as Heavy Varmint would make sense. What balance issues could I run into when pairing this barrel setup (say 26") with stocks such as a McMillan A% or Manners T4?

A front end heavy gun will shoot just as good as a balanced gun BUT it is so much work to shoot it isn't worth it.
The barrel contours and length you are talking about are relatively light for a competition rifle but seem extremely heavy if your used to a hunting type rifle.
I have zero experience with the stocks you mentioned but the picture is of a Tooley MBR stock Remington 700 action and a 28 inch max heavy varmint barrel in 338 Lapua Ackley Improved.
I am inletting the stock by hand so no recoil lug in the picture and lots of tape.
If it doesn't balance I will remove the buttpad and fill with lead shot and epoxy until it does.

I have seen such heavy barrels used with lightweight stocks to the point that the stock only had a few ounces keeping it from teetering on the bipod and going muzzle down on the bench/ground.

You want the back of the gun to be heavy enough to sit still.
If you don't have enough weight in the back, don't go with too much weight in front...

The Markansamafterwork youtube guys add weight to the back with a piece of solid steel roundbar cut to fit the stock as a bagrider. Dual purpose low cost accessory.

Thumbs down



Here is one of my heavygun stocks setup for a 1.750 diameter barrel 34 inches long showing the round stainless bars. They add weight but they also keep the gun from rocking side to side. If your stock has a flat bottom banging the bolt open and closed will make the sand buildup in the middle of the bag and hurt accuracy.
By placing two points apart from each other sand buildup in the middle doesn't allow any rocking motion.

Thanks Lynn. Damn, I thought I was going really heavy with the Bartlein Heavy Varmint at 7.5 lbs. Guess I need to get to one of your shoots above Clear Lake and check out what setups are being used.

Thanks Randall. Gives me some more to think about on the build.

One of our shooters has some barrels 2.5 inches in diameter that are 45 or 48 Inches long weighing 67-69 pounds just for the barrel.
The picture is of my 338 Lapua Ackley Improved with a 1.750 Lilja barrel 34 inches long and the gun weighs around 45 pounds.
You can hang a 1.250 straight cylinder barrel 30 inches long off of a Remington 700 action.
If you go larger you need a barrel block or the action will flex and ruin the bedding and that will wreck your accuracy.
