So you do have an objective.

Ya need one (Emoji) crying - not laughing.

If you have no objective in mind why mess with it? If the objective is shorter brass throw slow the bolt down either more as$ or less gas. Recoil reduction you can play with weight of the gun also. Gotta have a reason even if it’s just wonder what happens if I do this.

Only after your warm loads.... from what I’ve heard.

History?

Gotcha. Thanks for the info and good read.

You been searching the porn sites again?

Or we could sweet talk you into going across the street.

I do know they were running way behind on shipping when I ordered from them.

If I recollect most of 98’s loads are running pretty quick. I’m guessing he has a speed number in mind from the get go and when he gets it then he tweaks for accuracy. I’m far from a long range expert in fact I’m a noob at trying to get there. Been a hunting performance hound in the past but have changed my outlook. Some of the ways I did stuff in the past still hangs around cause I can’t let go. I’m just trying to understand his method and maybe could change the way I do it.

I got a trigger housing and ghost connector from the Glock store few weeks ago not sure what they have in stock now.

More ways to complicate shiit!

Waiting to see the end result too.

I guess there are minimum speeds based on use. I agree it needs to not transit into the sub sonic region to stay stabilized and accurate. Should be easy enough to determine min speed for that at the required distance. I was thinking min speed for best accuracy considering barrel harmonics if you subscribe to that camp. I use it to try to find the highest speed that would allow the barrel to be as accurate as possible then determine if it will stay super sonic at the distance I want to shoot all the while looking for pressure signs which are a little harder to detect in a gas gun compared to a bolt gun. I guess different paths to the same end.

@DayWalker what size frame?

Hard to tell from the pics but you may have tweaked it somewhere. Putting lower in vise - Lower to upper fit is common (looks like the front pin ears may be twisted), may have twisted upper. Can’t tell from pic angle but barrel extension may have rotated some. Do you have somebody knowledgeable close that can take a look at it?

Nailed it!!!

Not really but I don’t understand why you would ask about the charging handle related to a handguard change then post a pick of the bolt. Then not give any info when asked. Sounds like trolling to me.

I think your gas ring gaps are too close together.

10-4. How do you determine what your min speed is? that is basically what I’m doing - finding press/ speed flat spot then taking it off and tweaking for best accuracy. I just don’t know what the speed needs to be before I start.

Meh - new mouse trap. Nothing wrong with the old method. I don’t switch weights around often enough to warrant one.

Same one I got. Does what I need but I too worry about barrel harmonics. I’m using it for speed info and finding plateaus. I’m still figuring out how to do accuracy testing with it. Right now I find a potential speed node then take it off for the accuracy testing part. This is where a standard chrono or lab radar type would be better cause you wouldn’t need to take it off. Ease of set up and not shooting through a window is nice.

I get to see em all everyday just not up close. We are right in one of the popular Ft Rucker training flight paths. They fly right over the house as they go up and down the chatahoochee river. Those big twin rotor bastards can really shake the windows. The blackhawks are sometimes hard to see cause they barely clear the trees. Kinda fun watching them. I have never been up close or in one and would certainly not care to swing on a rope from one. That’s for you crazy fukkers.
