Hey fellas, anyone running GT barrel in 338LM?
Looking at running 250-285 solids and 250-300 cup cores.
Thx

What is a gt barrel ?
gt = gain twist
Sorry, tired and got lazy typing.

Hi,
IMO you should choose what bullet type you will be using and spec the barrel to it.
The twist rate you can run that spectrum of monos at is not going to be optimum twist rate for that spectrum of jacketed bullets.
Remember...very few of the jacketed bullets can take the twist rates that some of the monos like to be at.
It all depends on your "reasonings" of wanting to go mono vs jacketed and "reasonings" of contemplating GT vs straight twist.

Theis

Have a couple on the way, what twist are you thinking? For cup and core I wouldn't go faster than a 1/9.
Thanks fellas!
I am leaning toward cup core since I have a fair amount of 338 projectiles.
And considering that I dont compete, at least, casually, I think cup core projectiles are going to be it.

If you don't already have your .338LM rifle, Theis' company Hoplite Arms is making some totally kick ass rifles that can be pushed to much higher pressures than any other common rifle.

If you get interested, the first 10 rifles should be ready to be assigned to orders next month, so you might want to PM @THEIS if you are interested and let him know what chambering you want and what kind of bullet you want the barrel to be setup for.
That being said, however if you really want to have fun pushing the limits of .338LM, get a hoplite rifle setup for the solids and then get some of the Badlands Precision solids: https://badlandsprecision.com/shop/
Those solids have been tested and used very successfully by some folks that know what they are doing in the ELR game.
With a Hoplite rifle in .338LM and those Badlands projectiles, you would be able to have fun shooting at much further distances than you'd be able to with a standard rifle and regular lead core bullets.

Hi, Well I figured with everyone going off about someone not having any details or pics of their upcoming new product release, lol... Figured I would play the exact opposite side of the coin and just drop picture hint with the full alloy details. NOTE: We are not entering the receiver market at...

Some customers and I are have stellar results with 300g Berger’s and A-tips out to 2500. I don’t think you’ll be hindered either way with these or solids. But like mentioned before, get the right twist for one or the other.
I spoke with Dave Tooley about gain twist barrels and he is not a fan. He a lot of testing and there was no advantage to a gain twist. He did say he would how ever get unexplained flyers. I went 30 in 1-9 in my .338lm. I shoot Berger 300 HB and have made hits out to 2650 in ELR matches with them.
I’m conflicted, I’m not sure what I want to do for my next 338 barrel.
I strictly run solids with a 1-8 and can’t say I’m having any problems.
Not sure if I want to experiment, buddy is repurposing a gain twist from an older Lutz project and I’m curious how it compares to my straight twist.
I ordered a Bart GT 1-9---1-8, 31 inch early last year for heavy solids.
Debating if its getting chambered in 338 LM AI or 33 XC.

338LMAI has a aggressive GT for solids. I believe 1.5 inches of gain w good luck.
