22. AA fields ?

[kingoftoosh 15]

Awright . hope some one can help with this one. was thinking of trying Air Arms fields in my S16.When ordering two sizes are given .Both 5.51 and 5.52. What is the difference ,what do these numbers mean.

Also if these pellets are heavier than my Accupels ,what difference will this make to Tracjectory,range + power.

Cheers for reading

Hey Buddy,

 

Traditional .22's are 5.50mm.

 

Now a .22 bore is 5.50mm wide yeah?

However there is Rifling to take into account, soooo the rifling may be 100th of a mm or even 1/200th's of a mm.

 

I choose 5.52mm pellets as, when the blast of air up their skirt expands the skirt to fill the rifling it makes a good seal, hence all the air is is used to propell the pellet forwards. where as a 5.5mm pellet would do the same but it may not expand enough to fill the rifling.

 

However a 5.51 pellet may be enough to fill the rifling perfectly.

 

I would suggest that you try at least 50 of each to get the very best grouping on your target.

 

A 100th of a mm may not seen muchbut to a perfectionist, it can mean all the differeance

Cheers Phantom. Do you know anywhere that would do sample packs of fileds?so i can try the 2 sizes.

If not think 5.52 sound the better option as they are more liable to give a better seal.

Hi there King buddy,

 

You will probably find that the power of your S16 will increase a slight bit (not always the case but 99% of the time) with the 15.9 grain Arms Arms Field pellets but the POI will change slightly lower due to the parabolic trajectory being slightly more curved when using a heavier pellet than the 14.3 grain Webley Accupells.

 

This does have its bonuses though pal as AA Fields have a much better Ballistic Coefficient than Accupells meaning that the pellet will fly better in the air due to having less drag. It also retains it kinetic energy better at the target end.

 

The hold over issue can be solved by a bit of range time and learning your own combo’s new trajectory mate but the benefits are well worth the effort.

 

All the best anyway pal.
