.308 Corsair Long Range Session (part 1 of a 4 part series)

Hey guys, and welcome to another one of my H.P.A. expeditions.  On this trip and in this series, i wanted to dwelve into some BASIC long range shooting with my airguns.  In this first installment, i opt to start with the .308 Corsair. A gun and bullet combo well suited for long range shooting.  The gun is making roughly 240+ ft lbs and has a true bore diameter of .308".  The bullets that i shoot through the gun are sized to .308" diameter and cast by myself.  I have found that in my particular gun, .308' works better than bullets sized to .309".  I start the day off with a simple sight in to zero the gun at 100 yards.  The gun proves to be plenty accurate at 100 yards as a few bullets that i used that day printed 2 shots touching each other.  The three bullets are the 135 grain Spitzer, the 148.5 gr RCBS HP and a 155 gr LEE mold Flat Point bullet.  Remember, this is an airgun and not a powder burner so shot count is limited per fill.  At 3600 psi, i get 4-5 shots but only the first couple are consistent in velocity and accuracy.  Its the nature of a big bore airgun.  You simply don't buy them to shoot 20-50+ shots off of 1 fill.  You buy them for all out POWER.  Lets take a look at a few targets from that day:

As you can see above, the accuracy is there.

After sighting in and getting the POI pretty close, i then set up some of the REACTIVE targets that i brought along.  REACTIVE targets are basically anything that you can shoot that simply lets you know you hit it.  Such as a can filled full of soda, or an aspirin tablet or a jug filled with water or even a metallic swinging target that GONGS when you hit it.  I set up 2 water bottles/jugs at 91 yards and hit one with the 308 Corsair and the other with the Jack Haley 457.  The targets fell easily at the shots.  I then move out to 100 then 150 then 200 yards with my steel swinging target that sways when its hit with something powerful enough to make it move upon impact.  At those distances i also managed to shoot a MELON and a couple of jugs filled with water.  The gun/bullet combo proves to be accurate and have plenty of potential all the way out to 200 yards.

During the session which you will see in the video, my rear scope ring is not tight and the clamp manages to come slightly out of the dovetail groove on the receiver.  My groups all of a sudden move upward and the gun continues to shoot a tad high for the remainder of the day.  It was not till i went home that i found the issue.  I reset the rear scope ring and also REPLACED the entire scope with another that i had on a gun that i don't shoot too often.  So that should resolve the POI issue on the following shoots with this gun.

All in all, i am very pleased with the gun as it performed very well at distance.  Probably better than i thought in the beginning even considering the scope malfunction during the making of this video.  Lets go ahead and review the video and it explains the story in more detail.  ENJOY:
