Cut 1/8in off your barrel and re-chamber 6GT.I'm looking for load data on this setup for a 6x47 L. I'll be running a 30-in Krieger 7.5 twist. I'm thinking about running the 115 Dtac. But any in all information would be greatly appreciated.
I am looking for information on the 47 not the GT.Cut 1/8in off your barrel and re-chamber 6GT.
No necking down, excellent quality Alpha brass
Factory ammo available
20% less powder and recoil for same velocity
20%longer barrel life
Exactly what I'm doing with mine.
Death of the x47 began with Creedmoor and will end with GT. x47 is a moribund cartridge and brass will become increasingly scarce over time, as GT becomes increasingly available. I expect x47 to eventually meet the same fate as 22-250 in Lapua's production line.
In that case:I am looking for information on the 47 not the GT.
The chart is for 105-107gr bullets, but you can probably extrapolate by reducing STARTING load by about 2gr. Velocity will be about 200fps less.In that case:

There is an embedded load chart for 30in bbl
Yes, but only with 107SMK.Has anyone tried? VV 160
Same.....I run a 30 inch Kreiger....39.0 H4350, 105/108 Bergers. CCI450. 3100ish and a mild load. On my 2nd BBL. Cut the first one down to 16.5 inches for suppressor use. Lost a boatload of speed, though....down around 2730 with the same load.105 Berger’s out of a 30 inch bartlein 39.3 gr of h4350. 115 dtacs 39.2 gr of h4350 both shoot great
A1-8 twist 30” with cci450s a fire forming load of 39.1 H4350 2.083 depth should get about 3164 fps! At depth of 2.104 (hard jam) with 40.5gr H4350 should get you about 3187 fps! When you hit the sweet spot (3shot group) you should be about .450-750” at 600yds! All testing done at 3331ft elevation! Loads get finicky if you don’t use cci450s depth used stony point off ojive!
What bullet were you shootingUnless the chambers are cut with the same reamer coal is all irelavant.
My loaded round is .008" into the lands, and I found 42.3 grains of H4831 to be my sweet spot. 3157 fps and .2 moa, and less than 10 fps ES.
39.5 grains of H4350 gave similar results but over 20 fps ES,
Hottenstien 108 barn burners. But Berger 108 EH shot almost as good with consistency going to the Hottenstiens.What bullet were you shooting
