How did the 8.0 at 169PF shoot was it flat at all. As I'm shooting at 172PF and Adam said I could bring it down to 169-170PF and still shoot flat. I haven't tried it yet. 


It was pretty flat. I'm going to go with 8.1 and see how that is.

Atlas just released their line of tuned magazines.  Prices aren't too bad, equivalent to MBX prices.  The tuned mag that came with my gun gives me more warm and fuzzies over the MBX, though they do run well.  The one MBX magazine that had some issues is getting replaced by MBX free of charge.  Great service!

 

Point is... it's a good option.

so today i tested some new ammo out of my gun and 7.1 was the cats meow. the gun was so smooth and flat it felt like you could shoot it with just your finger tips. im in love with this thing! 

 

i did try all of these with small pistol primer and for some odd reason 6.8 showed some cratering, and 7.2 had some flattening but 7.1 had a nice profile to it. ill post pictures of that later.

Hells yea dude!

 

 

I was about to say gman! Lmao. 

 

I'm fighting pretty consistent light primer strikes right now. I think it's from not fully seating (I go pretty slow trying not to spill powder)

Is this the extra short-flat trigger or just the short-flat?

That's extra short. Mine has the short

How did you two locate your GoGuns gas pedals?  Is that just the way they came from Atlas?

Seems odd that the gun with the longer trigger has the thumb rest closer...  and the thumb rest farther away on the gun with the shortest trigger...  Curious?

That's the way it came from them. I definitely like it though. I honestly don't think you have to look at those together. It's more overall hand size not so much trigger finger reach. I have seen people with massive hands like super short triggers and vice a versa.
