Texan 100 yard .30 Cal Jsb Pellets Grouping Pics Included. I ask for more tips.

[Shooting Targets]

ok folks I have included some pics of my groupings at 100 yards. The first couple on the black target were rough gauges.

This was shot on a bench Airforce Texan 30 cal with air moderator and 50 grain jsb heavies, fill pressure about 2400 to 1800 is where it seems most accurate. I can get about 20 or so shots off a fill. Do you guys have any tips on better accuracy ? The lowest shot was the highest pressure of about 2300 on this. As I shot the rifle starts to increase velocity and the highest show was about 1950 PSI. The velocity is fairly low probably around 850 to 1000 fps. The shots have a tendency to creep up until about 1700 PSI. So I shoot from about 2400 which give me a lower velocity until about 1900. I am thinking of trying to shoot this theathered for better accuracy lets say at 2100 psi. Any other tips would be great.

I thought the Texan had a 308 unchoked barrel made to shoot slugs?

 

[Shooting Targets]

Yes it does. I been shooting all types of slugs but accuracy has sucked. When I shoot the JSB pellets they seem to be the most accurate. I want more shot count and a little less power to enjoy paper punching. I can probably get 20 to 30 shots out of 1 fill. Thou I have to account for the drop in fill pressure. At 25 yard no big deal. At 100 yards it because a big deal. Still trying to figure the gun out with fill pressure and setting to get the most accurate shot count possible with the most shots. Power is not really what I am wanting because any small animal will probably be dead at over 100 FPE.
