    Pappabear, what load are you using for 4064? I'm working up a load for my MWS.

    We switched 4064 lots and lost 100 fps. I feel like our charge weight would be somewhat worthless with the huge variance in lot velocities. I think the load was in the mid 42 grain range. I could check if you want.

    Sure. I need a good place start.

    41.5-42.0 is a good gas gun starting load, and where I started on all 3 of Pappabear's LMT MWS barrels. Even if you have a faster lot of powder, you'll be safe there. 44s are where you're getting into bolt gun pressure levels with 4064.

    Thanks. I'll start there and see what I get.

    Depends on the Barrel too. Pappabear had a barrel that just shot really hot... even on the starter load around 42.0.

    I have a FN SPR and it shoots MOA, but we run Varget for our Bolt guns. What custom are you getting?

    With the 178 eld’s out of a gas gun, how are the speeds? I haven’t tried them but shoot the 168’s. I thought about trying the 178’s but haven’t yet, thinking since they’re so long it would screw with case capacity and I wouldn’t be able to get the velocity up to really take advantage of the bc.

    We're taking another pass at the 178s. I loaded just under 250 of them yesterday, so I hope this load is decent.

    Trying them with IMR 4064 in MEN brass.

    I prefer 1:10 or 1:11 in my .308s. The 1:12s don't seem to handle the higher BC bullets nearly as well. Also, don't get too crazy on the FPS, i'd rather save my barrels and enjoy them a bit longer than pushing the pressure mark. 2350-2400 is fine for me. If you can get more, great. The .308 bullet options have also come a long way. I mean BCs available in the .7xx range are pretty awesome for this old cartridge. Just sold an AR10 and hoping to get a bolt gun build going in .308 or 6.5 soon. Cheers.
