Reloading for GAP team rifle 6mm

[Rebel Rooster]

Hey guys,

I just received my new GAP Precision 6mm, and it has a twist of 1:7.7. I've been doing some searching regarding bullets for reloading, and I'm wondering which Berger would be the best match for this barrel. 26 inch barrel, and I will be shooting it out to about 1000 yards. Thanks in advance for the answers. I tried doing a search, and I did find a bit of information regarding the 105s and the 115s, but I was a little befuddled.

6mm what? The hybrid is a better more forgiving bullet, one seat depth will toast a barrel. With a 115 you may end up chasing the lands and re-tuning the load every so often.

115 DTAC’s shoot the same spot at 705 yards from .04-.06 off the lands on my barrel so I stuck with it.

Sorry about that 6mm Creedmoor.

Berger 105 hybrid, H -108 ELDM, 115 DTAC. They will all tune easily and stay tuned longer than both the Berger 105 and 115 vld.

The 105 hybrids shoot great in the GAP team rifle. For me, the DTACs also shoot well and the higher BC makes a difference at 800-1000. I got slightly better accuracy with the 105 Hybrids, but the BC advantage of the DTACs gave me better overall results for long range matches.

Thanks so much for the info!! Do you mind sharing your load data?

Although it has no cool factor, the Sierra 107 SMK is a solid performer in my rifle.

For the 105s, I was using 41.7 H4350 and getting ~3100fps, and for the DTACs I was using 41.4 H4350 and getting ~3015fps. This is after the first couple hundred rounds when the barrel sped up, and before about 1000 rounds, when the barrel slowed down.

Thank you so much. That really helps give me a start

I don't load for 6 Creed, rather 6x47, I just know these bullets are less sensitive to seating depth tune.
