I accidentally bumped the barrel and the poi went wayyyyy off. That's what got me trying it out, looking more closely, and a trying a few fixes. The barrel band I made. I shot a few shots, dialed in the scope, pushed the barrel up, down, left, right and then again. Still on target at 50 ft. But that was just a few shots. More testing in days to come. How fixed is your barrel? Does it move when you push it around?Hey RionSpotted this barrel issue is as soon as I removed the shroudBarrel movement no matter how tight it may be, is very noticeable with the shroud removed. So dating back to my fortitude days which had a barrel band, it still needed an install of some bridging to correct this drift.unfortunately I'm somewhat in a stand still posting pic's (kindle fire, camera pics or prt scr shots )BillWhat sort of bridging work did you doon the fortitude, Bill? I have one too, hence my askin.

People have argued back and forth about barrel bands for a few years now. My reasoning is that I have at least 2 feet of barrel tube connected only at one end by one or 2 grub screws to hold steady the inch or two it sticks into a receiver block. A small bump at the free end and you change where it is pointing slightly, which can be a lot when you are shooting. So anything that is going to keep my 2 foot tube from moving at all might be helpful and just might keep the shots consistent since the barrel is not in any danger of moving around at the far end. Most shooters, when zeroing a scope, actually clamp their entire rifle into a lead sled on a bench so that it won't move. Same principle. Consistency.
The band on the fortitude is loose. It's puprose to my mind is to prevent bumping of the barrel from causing too much damage.My fortitude is not the best accuracywise. Maybe a rubber shim in the shroud will help. Project for another day. Trying out my rubber barrel band on the p-rifle is next on the list!
Yes, it is regulated.
James, have you tried shooting the p-rifle/p-carbine at w5 or more yards with the normas yet?Beginning to suspect the gun might prefer heavier pellets.
10 meters?
Well this is interesting. Got 50 shots instead of 40+. There was an oddball shot at 809 fps, which made the ES 30 on the shots I chrony'd at begging and end of string (first ten, last ten). The 30 shots in the middle were for a casual match target. I'm comin for ya James, using your gr weight recipe against ya [chuckling]. I got a 197/200x at just under 50ft. Much better than the ftts were doing (more like 180s).This is all with the BHE 18.52 gr.

The heavier pellet is staying in the barrel longer utilizing more of the air, and helping to close the valve. Lighter pellet is exiting the barrel prior to the valve closing. Fix would be to lessen the hammer spring when using lighter pellets.
