Tell us about your Midwayusa AR Stoner barrel.

That's quite a bit of extra speed. If it comes at the expense of added pressure, the loads might not be safe. Exercise caution.

If possible, try some loads through your chrony where the speeds are known or predictable, preferably with a different rifle and ammo that are known to be safe.

If you haven't already, check your chamber for COL and make sure that your ammo is tailored accordingly.

Err on the safe side until you get a better understanding of what's happening.

I'll be running factory so we can compare the same 24" 5R Stoner and see how much he is getting from his than mine. I hope to have my 16" MLGS Stoner ready to go by then too. just need a comp in 9/16-24. Don't want the Heli-Port Muzzle Break they offer, I want some recoil help. I think someone has a trnd here on them offered in SS and Black but need to see how his turns out and might go that way. So getting the 16" finished might take longer to get than me getting to use a Chrony.
