Forget that. Sounds like a another berger seating depth goat rope

Same for me. About 1" groups in my model seven, which was as good or better than anything I've tried, including several different factory offerings and several hand load combinations with 80 gr TTSX. I killed several deer with the GMX and was impressed, however I later bought a chronograph and found that these were only shooting about 3010 fps in my 20" barrel. For comparison, I'm getting 3180 with the TTSX and 1 grain under max load of RL 15 with less recoil and muzzle blast, which is important when loading for a 9 yr old.

I have never had a problem getting very good accuracy with the TSX or TTSX. From the 222 Rem to the 416 Rem with a bunch in between. And performance, well always stellar. As such, I do not play with others.

Every cartridge I have loaded with Barnes TTSX has performed well. No reason to mess with GMX or other monolithic bullets at this point. The 150 GMX shoots fine in son’s Garand for plinking. I bought a bunch of blems cheap from Midway a few years ago. Happy Trails

I guess TTSX it is

I have a model seven ks that shoots 139gmx well under an inch....consistently. I'd have to look up load recipe. It was my first try with them...same thing with 140 txs and ttsx. It's just one of those rifles that will shoot anything

I've never seen a TTSX that didn't shoot lights out with a max (or near max) charge and the bullet seated to the front of the first driving band. 243, 260, 7-08, 270, 30-06, 308, 338, 375 H&H..

In my 7X64 they have been OK, definitely something that I would hunt with. Not as accurate as others and not as high a velocity. Still well within my standards for a hunting load. About 1.5" at 100 yards for 5 rounds. About the same result with factory Barnes TTSX loads. The GMX were reloads.

I ran two boxes of factory Hornady GMX ammo through my Ruger M77 7mm-08 and killed a spike elk at a little over 100 yards with one shot (through and through, hitting bone low front shoulder). The wound channel was pretty savage, but bone chunks seem to help tear shtuff up. The accuracy at the bench was from the high .5's to low .7" with 5-shot groups. After seeing the x-rays of lead in harvested game animals, I wanted to try some monometal bullets for the health and safety of my family. Even if a cup/core bullet retains 90% of its weight, that's still 14gr of lead seasoning in my meat with a 140g bullet. No. Thanks.

My buddy just tuned-up a Savage Lightweight Hunter in .308 and has some Cutting Edge bullets in copper and in brass to try out. If they shoot well for him, I might also give them a try, but they are quite spendy when compared to factory Hornady GMX fodder, which has already earned a place on the shelf in my book.

So all grooves are seated in the neck?

Not my pic, but just like this. Maybe a hair above the neck so crap doesn't get in. Yes, I set the seater die by eye. Measure later.

Copy. I’ve gotten acceptable accuracy but never “lights out” that alotta folks get... ill have to try the 80’s in the 6 ai again...

Maybe my lights aren't as bright, but MOA or better.

Ya I had em moa in my 6, the 80 BT’s were better so I ran em and killed several big deer with em. I’ll mess with the seating a little more see how they doo.id like something to dig a little deeper for bears and bulls..

I seat 0.050" off, and they always shoot.

I never got a 3" group with them during load development (30-06, 270, 300 WSM) BUT out of the three (Barnes TTSX, Nosler eTips,Hornady GMX), they gave me the largest group. Actually it was in that order from left to right tha gave me the best to worst groups. The GMX did shoot sub-MOA Just not one ragged hole.

If you look at MCMXI image of his target on page 1. My group with the GMX looks like his 3 o'clock orange dot.

Hello I have just gotten in to reloading. Have purchased some GMX 180gr for my 300 win model 70. I am having issues with the distance they have to be into brass base of bullet seems to be quite far past the shoulder with one grove showing above neck that’s as long as I can go to run through my rifle. .134 off lands any help appreciated.

Andrew, you've landed in an old thread. You might want to check out the big game reloading forum here and pose that question there.
Welcome to the fire.

OSU_sig. Thank you

120 grain superformance shoots real well in my daughters 6.5
