Just about there...

Hey fellas, 

I've finally gotten to the point where I'm actually going to start loading...(finally, after years) and the last piece of the puzzle is which powder to finally decide on.

I've got 1k primed Lake City, pulled but never fired brass cases and Hornady 178gr ELD-X pills......I was leaning towards either StaBALL Match or Varget, but would really like to hear if anyone has used a similar mix of load components...

Main purpose of the rifle with mainly be comps and maybe some hunting with it, unless I decide to build something on the smaller platform...

Included older pic of the build, currently doesn't have an optic on it, trying to decide between the 2 that I have...

Brother, you are speaking my language now!  

I specifically worked up Lake City brass and 178 ELD-Xs for a new (then) rifle.  I used Accurate 2495 powder.  It's the best .308 load I ever came up with.  Honestly.

I'm not sure what the availability of the Accurate powders is right now, but it's for sure worth trying.  Grab a pound and try it out, you'll love it.

I am partial to Varget. It works well in 7.62 and 5.56.

I was actually going to message you yesterday about it since we've talked about it before, but didn't want to bug ya...

I just checked, 2495 seems to be in alot of places, so that shouldn't be a problem.....what kinda specs did you end up going with your rounds?

CCI 200 primers with 40.6 gr of 2495 gave me 2530 fps from an 18.5" barrel.  I haven't chrono'd it with the Garmin, so that speed number is old.  I need to get it out there and put the little radar on it.

what did your case and overall length end up being? I need to get a chrono badly, which one would you recommend?

Varget gets my vote.

I'd say check your brass length after every firing, but you don't necessarily need to trim after every firing - depends on case length.  

Trim-to length is 2.005" for the brass.  I'll let them go to about another 0.010, to 2.015", and still load them  - it they get over 2.015", I trim them back to 2.005".

Since it's a mag-fed gun, I keep the loaded overall loaded length to the max length, which is 2.800".  And, since it's a mag-fed gas gun, I crimp every single one of them with the Lee Factory Crimp Die.

Notes about case length, crimping, gas guns, pressure, and precision...   Let's talk about un-equal case lengths.  If I have a bunch of cases that are all not the same length, and I set up a crimp die on a short(er) case - it's gonna put a heavier crimp on that long(er) case...  More (longer) brass to squeeze...  which increases initial pressure, will have a higher muzzle velocity, and have a higher chamber pressure...  That's your "flier" when you're shooting...  Same with short cases - not as much crimp, lower MV, slower out of the barrel, lower chamber pressure, falls short of the target, or lower on the target.  

Trimming to the same length definitely affects precision at distance, it affects SDs, chrono data -everything  Trimming is a big deal.  Equal case length is a big deal - for precision.  

Chrono - highly, highly recommend the Garmin Xero C1 chrono.  Fits in your shirt pocket.  There's a new C2, little more expensive, and faster technology hidden inside.  The C1 is so badass, that I don't see a need to pay more for the C2 and it's benefits  - unless I'm winning major prize money at this...  

That's my soapbox, brother...
