6gt

[farrar86]

That fast with the 115s holy crap lol. I assumed 109s.

Have you shot them at distance? I was having issues past 900 with 109s. Would see it miss off either side of the plate. 800 and in it was me if I missed.

Yeah I’ve been shooting them for years now, they do well for me at all ranges I’ve shot them at. Very consistent when I’ve switched from lot to lot.

Has anyone used the 308 conversion kit for their xl650/750 to load 6gt?

 

[farrar86]

I'm using a 22-250 kit. Works fine. Did find it doesn't seat the primers (BR4 or 450s) deep enough to ignite consistently.

 

[The Knuckle]

Yeah that’s the go to but I have a 308 kit. It looks like the powder funnel, case feed body bushing and adapter are the only things different between the 22-250 to the 308 conversion. Hand cycling the case feeder seems to work so I was hoping someone else tried to use the 308 kit.
Maybe the powder funnel will give me trouble but I will e dropping charges by hand.

Gotcha. I'm just using it to try and save some time on FL sizing and de-priming

Has anyone tried to progressive reload 6mm GT with CFE223? Seems to be a growing approach for loading 6mm ARC.

Guys running stiff loads of cfe223 in a 6arc pushing 6br velocity are likely running 65-70k psi, barrel life will be no better than a 6br. The 6arc is 34.5gr capacity, the 6gt is 44gr. Cfe 223 might work in a 6gt with 60-80gr bullets. But for heavies, you need slower powders. If you must run ball powder, try stabal match.

I'm interested in the option to progressive load. I'm not overly concerned with barrel life.

I have tried Stabal Match using an automated press and automated volumetric dropper. The results were meh.

What bullet weight are you using? 2958 is moving along for a gt if those are 105-109gr.

A little zesty, true. I have a second test batch but haven't had time to shoot it yet. I was using Berger 109gr LHRT. Alpha Brass, 450 CCIs.

Next best powder is likely Stabal 65, 37-38gr. I don't have cfe223 to try, nor have I saw it in any load data.

Oh I tried Stabal 6.5 first . That was 21 SD 49 ES.

I'm tempted by what I see with folks being able to progressive load 6 ARC with CF223 and end up with ~6-7 SD.

While I was using a rcbs link, my SDs where in the 20’s with StaBall match. I was expecting better. Also was planning on using it on a progressive, so interested to hear what you find.

Anyone shooting a 7 twist with 109’s? How is it?

Thats what I’m shooting. Only taken it to 600 yds, but it’s a tack driver.
Last 5-shot group measured 0.142 MOA @100
I was floored!!!!
