Question for you 308 gas gun reloading gurus.

I have had excellent success loading 308 using both Varget and RL15 getting +/- 1/2 MOA in my bolt guns and typically 1 1/2 to 2 1/2 MOA in a 308 gas gun. I find very minute differences in accuracy / velocity between the two.

I will keep using RL15 and Varget in my bolt guns for precision but want to reload “accurate” bulk ammo for the gas gun. I tried doing this with a hornady progressive press using Varget and rl-15 and got very very inconsistent powder charges and gave up.

Depriming and resizing were done off the progressive press when I tried this little bulk loading experiment.

I know BLC-2 will meter well (likely the same as other ball powders i use for bulk pistol loading) but will accuracy suffer given the type of powder compared to Varget and RL15 (ball vs stick). Obviously Load development will be required.

Is there a more accurate ball powder i should try instead of BLC-2 for bulk loading?

Any experienced guidance is appreciated.

i to prefer r15 and varget but win 748 works well and as a ball powder meters well..only thing you might want to try cci 250 primers with the win.
 
Been using BLC-2 for years in both bolt and semi. It can be as accurate as any powder. I know Varget is the most popular, but you can get consistent accuracy with BLC-2 - just have to find a load that your gun likes. I got bored shooting at 800 meters with an SSG-69 using BLC-2 and 165gr Hornady SST's. My hunting load.
 
BLC-2 has been a faithful standby for gas guns for years. I have managed great accuracy with it. I have set it aside though for CFE223. Meters every bit as well and I have gotten some very good velocities and accuracy in .308 and 5.56.
 
If you want to make accurate ammo on a progressive, ball powder is where I would start. BLC2 or 748.

My son made about 500,000 rounds of match 7.62 using a ball powder similar to BLC2 and 155 gr bullets. For heavier bullets I would try 748, too.
 
Another vote for CFE 223 here. I know the copper fouling eliminator is kind of a gimmick, but Win 748 is a very similar idea. I found CFE 223 to be one of the most consistent powders to drop through my powder measure and it's on par for velocity to Varget. One thing to keep in mind though is it pressure peaks fast (Max charge is the max charge, no room for going higher.) I have switched my 223 handloads to CFE 223 and once I get a lighter bullet dialed in for my 308 I will switch to that for a plinking load.
