Well I broke down and bought another one of those "junky" Leupolds. I mounted a 3-9x40 "Ultimate Slam" on the .450B and took it to the range today with a couple of 250 grain FTX loads. 37 grains of Lilgun produces about 2170fps in my 16" rifle. I sighted it in at 100 yards in 5 shots, then put up targets at 100, 200 and 300 yards to try out the SABR reticle. Pics are below. I'm happy. I took no special care, and didn't let the barrel cool, I just loaded them up and banged them out. 100 yards to 200 yards is a no brainer. Low and dispersed at 300 yards, there is no "dot" for 300, you're using the top of the thicker stadia on the lower half of the reticle, and that completely covers the 2" circle on the target at 300 yards. A good trigger would have helped at 300 and after today I may spring for one.
The 100 yard berm is on the left in the sun, 200 yard berm is on the right in the shadow and the 300 yard berm is in the distance down the middle. The orange dot is 1 1/4".
