Advice wanted please
Hi Bartman, I am assuming you have the basic reloading Kit, including scales and Reloading Manual.
I would load five rounds of each powder weight, from Starting load, in 1 grain incruments.
For example if the powder start load was say 40 grains, then make up 5 rounds at that weight, then 5 at 41 grains and so on, up to the Maximum weight.
Take these to the range and WITH A GOOD REST, fire three or five shot groups, allowing your barrel to cool between shots (it doesn't matter where on the target they go as you are looking for the tightest group) this can take A LONG TIME.
In all probability the Maximum load will not give you the best group.
Decide on the best group and if you want to fine tune, then load half a grain either side of that load and try them.
Now you can concentrate on Zeroing your rifle.
