Damn. Missed it again. But I have 250 pcs of Hornady so not the end of the world.
Would you happen to know how many rounds is need for a two day match.
Usually 200
ok thank you
Usually 200~ish. More for a train up. I took 250 to Peterson last month. But I just checked zero and confirmed DOPE right at close on Friday before match.
Thanks I’ll try that.
Ok 250 ish to be safe . Thank GOD I just ordered 200 more , that makes 600 alpha brass for me and my son . 300 each . Plus Another 250 from hornady ,that we have as spare ,in case we ever need them .
I’m sure you know the load may be a bit different between the brands. So if you use the Hornady on Friday train ups, you may have different dope on Saturday and Sunday. Just keep that in mind. Aim small and miss small! Have fun. I’m guessing it’s your first 2-day.
Anyone running IMR4166? I have 16lbs and am about to spin a barrel up. I was going to go with BRA but now I’m leaning towards the GT with the DTACs I have.
Is 4166 truly that close to Varget in charge weight?

If you do run the 4166 ,please post your results ,would like to see them . Me on the other hand just got my 6gt barrel installed yesterday . So about to start a load ,with varget , then with h5350
I’m on same route. I have a few lbs of varget and h4350 but am always interested in new powders.
Dude in the 6GT FB group ran some 4166 (https://www.facebook.com/groups/780746612323086/permalink/1339804299750645) and got some reasonable results. 3059 avg fps / 3.6SD and printed pretty nice on paper.
Spinning up a 6GT next week myself so watching these with interest as I, like others, have a limited supply of Varget.
I'm not running 4166.
But, according to the Hodgdon website, starting charge weight for 4166 is 29.5 grains
Starting weight for Varget is 30.6 grains
They both show a max charge weight of 34 grains.
This info is for a 107g bullet.
In my BR with 105s it was pretty close. It think I used a touch more 4166. It gave good speed and accuracy, but I did a complete work up and not just throw a Varget load at it and hope it worked.
we started our load today and we are at 33 grains of varget , we are in the mis 2800's with mt 28"proof. we are staying at that speed .
This is great to hear, Brian is shipping me my GT build as I write this , I also went with the A-Team Mullerworks barrel, also went with Impact action!
Just got my 26” 7.5 6GT barrel from GAP. All I have is SW Precision and H4350 with 105 hybrid and cci450. Couldn’t find any solid data on here, can anyone that’s using similar, provide me with a good starting charge? Thanks.
You should be safe treating SW Precision as a 1:1 replacement for Varget, just work up from a light load because you may get a little more pressure (maybe not too).
I tried that initially but had excessive pressure. I think StaBALL is too slow burning for that case size.
StaBall seems to work better for the heavies like the 115gr Nosler or DTAC
All of them have had good results. I'd grab varget first, but if you have more 4350 that'll do just fine as well.
Got 2 8lb h4350s, maybe 8 1lb vargets...
On a gap cut chamber, using the h4350 any starting grains? Gonna use the hornady brass I first got. Have alpha now as well, but I'll start with hornady.
Thanks

I thought I saw a post on this thread using Shooters World Precision Rifle, but can’t find it now?
I'd start somewhere in the 33 gr range for varget and maybe in the 34 range for 4350.
Those are top end values, I would DEFINITELY NOT start there.
I know / shoot with a couple guys locally who feed their 6GT's a steady diet of 105's and StaBall and have excellent results.
33 gr of varget is where i am at . Not going to move from there, I am at 2875 FPS average ,
Just got 400 Berger hybrid 109’s and my rifle just showed up to my FFL yesterday!!!!!!!!! Gonna do a lot of testing
is it a 236 or 237 barrel
Don't do a lot of testing. Just pick a speed and shoot it. 6GT is extremely easy to load for. Spend your time shooting, not load developing.
Personally, no.
That’s pretty misleading. I can’t speak for the other matches, but at the Pigg River match, there were only 3 gas gun shooters.
Are you sure? I would double check that data. 37.1 gr of H4350 has 109s going 3005 fps. 44.1 feels like it would spill out of the case.
