Fps at .25 vs .28

[steverebo]

So I have always used .28 bb's but ran out while tuning my guns fps on .28 I was hitting 275 to 279 just Iver a joule when I put. 25 in I was getting 295 1.17 joule

 

Is this normal as 1.17j is over the 1.14j limit I won't be using .25's with aeg on the field but the huge jump concerns me

Assuming your site is running the standard 1.13/1.14j limit, then with 0.25s the limit would be around 313fps.

 

The lighter the ammo, the higher the limit is in FPS, and vice versa.

OMG I am an absolute idiot 🙄 

 

I forgot to swap my chrono to 0.25 for the joule calculation so it was still displaying 0.28 values
