If your reloading for accuracy a beam scale if the way forward they start at £60 for a half decent one checkout scopesdirect.co.uk
As for your oal its up to u to find the best.
Find your max oal then set your bullet 30thou back from it.
Then load several different weights up in .3 increments 22.2 22.5 22.8 23.1 etc load 5 of each
Look up your manual on go onto the powder manufacturer website for starting load weight.
Go out on a calm day really take your time.
Say your shooting 4 different weight loads 22.2 22.5 22.8 23.1
On your target put 4 aim points wigh the weight of powder write beside each tatget so you dont forget.
Lift out a 22.2 aim at target one
Then lift out a 22.5 aim at target two
Then 22.8 at target 3
Etc etc until u go around in a circle until yiu have no more bullets
The reason from going from one weight to the next weight is because you barrel will start to heat up and it wojld not be a fair test if 22.2 was shoot cold and 23.1 was shoot hot it called the OCW method look it up.
Once all shoots are fired measure you groups make a note of all especially the tightest group.
say 22.8 was you tightest setted 30thou back
Go home and reload 5 at 22.8 20 thou back 5 at 30thou back 5 at 40thou back 5 at 50thou back all will 22.8 grains.
Take them out check using the ocw method again which ever is the tightest group make a note go home reload 100 and go shooting
