I also tested the RL 241 gn, the RL 311 gn, and retested the 166 gn from Air Venturi, and HS... They are the same.First the 166 gnBelow 50 yards, these are very good, but at 100 yards they destabilize and corkscrew to the point they cannot be successfully grouped.From 3000 PSI fill (reads higher on gun meter)Shot 1 625.7 fps 2 619.7 3 646.2 4 656.2 5 715 6 738.6 7 812.8 8 923.4 2450 psi 9 964.6 10 946.6 11 929.5 1950 psi 12 900.7 13 886.8 14 866.4 1450 psiI'm sure most can see a significant level of valve lock, with the velocity peaking at around 2500 psi. This I don't see as a problem, and below 50 yards they are very predictable. Out to 100 yards they are unstable.Now for the RL 241 gnGun filled to 3000 PSIShot 1 896.7 fps 2 872.5 3 854.4 4 838.9 5 805.4These were very usable with the first 3 staying within a 4" group, which dropped down, and to the right with each consecutive shot. The 4th shot was erratic each test and would be 6-12" away from the group. The bullets seemed to start destabilizing at 100 yards, but not to the point they weren't usefulNow the RL 311 gn3000 PSI fillsShot 1 823.9 fps 2 803.1 3 783.2 4 758.2These 4 readings were the average of the 5 times I tried to get a group. The fps looks great, accuracy was pretty terrible at 100 yards, again a corkscrew flight path opened up to over 3 feet. I never tested these closer up.I do not tether my gun, I want to see what it will do in the field. But even with that proviso, I have only found 1 bullet that I can recommend for very accurate 100 yard shots, and that is from my last test. Much heavier than I need too. If these bullets are tethered they'll go down 1 hole at 100 yards.The RL 241 gn give 3 shots within a 4" group, but they move down and right, with much less predictability.All these tests are done on my Texan, for my use. I use a high quality tank gauge for PSI readings, not the guns meter. I haven't adjusted the guns valve yet, it's as it came from the factory.These results may differ substantially from your own guns, and I do not exaggerate, or doctor the readings... I would love to see your shot strings.It's harder to find a good bullet than I thoughtGeorge
FedEx dropped off my Texan a little while ago. I haven't gotten to do more than look at it for a few minutes, but so far the main thing I've noticed is that it feels very light. Much lighter than I thought it would be.Looking forward to shooting it. Have to wait a few days, though.
