24.8 gr. 0.217 Nielsen slugs worked for me @ 1120 FPS with a tensioned barrel. Orange pasties are 1". Impact MKII / 700mm barrel - standard liner (not slug liner).

I had a similar issue with a new human reg on filling VERY slow set at at 170 bar. I contacted Huma-Air and found out that there had been a revision on the number of Belleville washers that are installed for that regulator (1155). Mine came with nine and the instructions showed to use all nine...

No, the barrel end where the holes are drilled to reduce the weight. Thanks.

The width of the hole section. thanks.

Can someone please tell me what the thickness of the AirMarksman Backbone is? Not the wider part where the rail is, but the part where all the holes are. Thanks, Randy

Make sure your air valve closes before the projectile leaves the barrel.

Machined a spanner wrench to take the valve off my FX bottle. Worked real well.

You definitely need the tensioner on the 800mm barrel in .35 Cal. especially if you are going to increase the power. The Power Block will buy you a little bit, but its gain can be made up with a higher reg pressure unless you are going for a very high velocity then the PB would pay off. I have...

Looks like a feather-tipped boat tail projectile.

On my Impact 700mm barrel the 0.216"s were not as accurate as the 0.217's (both NSA 24.8 gr). The 0.217's pushed through the barrel with about the right resistance and had MOA accuracy at 100 yds. I didn't even try pushing through a 0.218" because it would have been too tight. As bigHUN said...

Longer distances are challenging but doable. One of my groups on the picture below could be improved vertically by weighing and lubing my slugs which I didn't do for this group. I did install a huma regulator since then to minimize the pressure variations from shot-to-shot to help the vertical...

33.5 gr. Nielsen slugs -Standard 700 mm liner - FX Impact - Orange sticky is 1" dia. - 100 yds. Never had good luck with the Hybrid 26 gr.

I have found that fiddling with turret adjustments while hunting does not work out very well. Many times I have had just seconds to get on a target and pull the trigger. Also when hunting certain critters like coyotes you don't want to be moving around adjusting stuff. A Christmas tree reticle...
