hello guys,

 

Im just wondering what the differences are between 177 and 22 cal?

In reality mass, diameter and weight buddy.

 

This in return give different ballistic characters for each calibre.

 

The larger and heavier .22 pellet travels slower in flight compared to the smaller and faster .177 pellet.

 

By travelling slower it is effected for longer by gravity giving it a more pronounced parabolic trajectory from muzzle to the target. The added mass and weight of the .22 is better at defeating side winds when travelling to the target though so not as much windage adjustment needs to be applied.

 

The added mass and weight also aids when striking the target as the slower bigger pellet doesnt over penetrate as much as the faster .177 pellet. This in turn means that more kinetic shock is housed within the target. This is sometimes called knock down power.

 

Due to the more pronounced parabolic trajectory shooters of a .22 sub 12 foot pound air rifle needs to understand trajectory and hold under and over better to gain accurate shots.

 

A laser range finder is a handy tool to use to help with exact range to target

But practice is what you need for aim points further than your zero.

 

Due to this fact many shooters opt for .177 as its easier to shoot accurately and requires less knowledge of ballistics.

 

At the end of the day its horses for courses and both calibres have their pros and cons.

 

My favourite is .22 but I will still shoot .177 at night when range finding is hard.

Hi Si bud,

 

Like You i also love .22 in Springers, But also shoot the Rapid in .177,

I've been toying with the idea of getting a .25 cal PCP sub 12 ft lbs, And remember You did a vid on that .25 Ultra,

What was the knock down power at say a Max of 55 yards, I know i would be looking at the bottom of the falcon menace Milldots :laugh:

But with alot of Practice with the .25 cal firing H&N ft in 20 gr weight what would the realistic Kill distance of a above average shooter be?

Or you could get a .20 lol

as has been said shot placement is the most important factor. hit the brain and jobs a good'un this is easier with .177 due to the flatter trajectory

but if you know your holdover/under aimpoints at different ranges .22 is still a great calibre.

 

i prefer .177 personally after 10 months shooting .177 to the 15 ish years i only shot with .22... im a convert!

 

also .177 pellets are cheaper LOL

Put up Google or YouTube and type in;

 

"Lewis and Clark expedition air rifle"

 

You'll see what a successful and very powerful PCP air rifle they had developed for their exploration of the American Frontier of the 18th Century.

 

Something like a .44 cal. Ball multishot!

Superb Simon bud

 

That repeating .44 ball air rifle was well ahead for the Year 800 lbs of power

Makes the sub 12 ft lbs .25 cal look like a pea shooter, Food for thought

Just was wondering the knock down power at the Extreme range of 55 yrds for the sub 12 ft lbs

if i did My part of the shooting.

difference is half a dozen odd shots more on a pcp verses 200 more pellets in .177.
