forward allowance, shotgun lead


Shotgun lead is normally just done instinctively, like catching a ball you don't really calculate where to put your hand to catch it you just do. Its the same with shotgun lead but there are 3 main ways people instinctively generate lead. Here are 2 videos to show you the 3 ways.  



This table is just to give you an idea of what amount of lead is needed. This is with standard eley velocity cartridges

2nd video, grass splitting

My 2nd video this time i'm using a browning t bolt . 17 hmr rifle, firing hornady 17 grain v-max bullets, scope is a Bushnell Elite 6500 4.5-30x50
i'm 50 yards away from the piece of grass it took me 2 attempts as its very hard through the scope cam which lowers the size and quality of the scope view
i was going to film shooting a rubber of the end of a pencil but there was grass in the way of were i was going to shoot so i decided to see if i could split it and i ended filming that instead

1st video :)

uploaded my first video yesterday afternoon have already got 200 views, its me attempting the 22plinkster's card splitting challenge. I attempt to try and split 2 cards in 1 shot. 1 is vertically placed and and the other horizontal, so you have to hit it perfect. On the second attempt i nearly did it but didnt fully split the second card, but tried again and again but couldn't do any better so i thought i would show you the shot even though i didn't fully complete the trick shot. one day i will try to get it perfect. please check out the video and subscribe as there is more videos to come this is just the start. info on gun and bullets are in the video

.177 or .22


There is an old debate about which airgun calibre is best: .177 or .22 hopefully this post will help you decide between the two

A .177 pellet travels at a greater velocity than the heavier .22 when fired from guns of identical power, but this does not mean that .177 is more powerful. For example:
.177 pellet weighing 8.4 grains, fired at 802 fps (244mps) = 12 foot pounds of kinetic energy.
.22 pellet weighing 16 grains, fired at 581 fps (177mps) = 12 foot pounds of kinetic energy.

The lighter .177 pellet has a flatter trajectory which means that hold over is less and more forgiving with range estimation than with the .22 over normal airgun ranges. The benefit of this is that targets are easier to hit with a .177 even if there are slight inaccuracies in range estimation; this is why .177 is the calibre of choice in Field Target and paper target disciplines.

.177 tradactory from 0-50 yards, the pellets in a 1 inch zone from 7.3 yards to 39.3 



.22 tradactory from 0-50 yards, the pellets in a inch zone from 5.5 to 30.4 yards
Pellets also have alot to do with it; the accuracy of the pellet means you can hit in the kill zone which is need for both calibres for a clean kill but more forgiving with the .22, the weight of the pellet also has a big effect as the lighter the pellet the flatter the trajectory for both but if the airgun is used for hunting you still need a heavy pellet so it has enough stopping power to kill.
Heavy pellets will also be affected by wind less. There is also a phrase: .177 for feather .22 for fur which you could also take into account

At the UK power level of 12ft/lbs the difference is fairly small, but as the power increases, the trajectory of both calibres flattens out so reducing the advantage that .177 would have over .22 at lower velocity. However, when a pellet approaches the speed of sound (which is about 1100 feet per second), it can become unstable, resulting in poor accuracy. This problem is almost exclusively confined to .177. The .22 really comes into its own as the velocity increases, when it’s heavier weight means that the pellets retain greatly superior down range-energy, and do not suffer from the loss of accuracy that can affect high velocity .177 pellets.
