I forgot to add.

Do all your shooting at 50 yards if you can, at least first up
and se how that goes.

I sometimes make it 50, 60, maybe 75 depending on the gun, how I feel, calibre etc but 50 is a good place to start.

Keep things simple and only change ONE thing at a time
with your loads otherwise you won't know what caused the change.

Re loads - nearly every load out there should be OK to use,
just drop 10% to start with unless you know it is well of the Maximum.
