Hatsan I finally cracked my AT44 code.

[airgunutty]

I have achieved harmonic balance for what I need and what I desire out of my Hatsan at44-10S qe long .177 I am sure that others will see these numbers and will consider them average at best. Any way here's what I am pleased with. I have a hatsan regulator set at 100bar. I'm using JSBM 13.43 at 950fps (27fpe) and getting 50 usable shots from 200bar to 100bar.

It just feels.....right. I don't know how else to explain it. It is super quiet. Seems like it isn't wasting air per shot. The shots are coming out with a super flat trajectory. I was able to find some of the shots afterwards and they looked great. You can see that the impact is almost dead center when looking at the skirt. These were shots from 50yds and I love the way these guys expand. That's definitely good when trying to be humane to the receiver of the lead-lazer.
Well that's what I got and I just couldn't be happier with my results.

AWESOME! Glad you shared your results. Nothing better than being tickled-pink with something you've dialed in right. Hope to see some pesting posts soon!

Also I don't know exactly how this is happening but I am zeroed out at 50yds and I'm dead center. Wanted to see how much drop or rise at closer distance to be able to adjust my poi. Went to 30yrd and 20yrd .Funny thing is that poi it didn't change. I may be using the wrong terminology but what I am trying to say is that I didn't have to adjust my elevation on my scope from 50 to 30-20yrd. Is this just the result of finding the right balance? Well whatever the reason it's a good problem to have. I would like to see what 100yrd looks like but that would mean upping my reg pressure which means going into the cylinder which means hand pumping from 0bar which means I sure am satisfied with 50yds.
Hope everyone is doing well and that you have a good day. Agnutty

Having a scope lower to the barrel helps. You may be able to use lower rings with your setup than people stuck with higher rings. Less rise for the pellet to reach your scope height zero.

Can you explain in more detail please ? I would say I have mid high rings.

Those rings are needed for the huge objective bell you have. Look at how high a bullpup gun scope has to be mounted to get a decent cheekweld. Your scope is closer to your barrel than alot of other setups that have to clear a tall mag or receiver.
