I had the pleasure yesterday of taking my ersatz M41B Swedishicon Mauser to the range and using an electronic target at 100m to work up a load. I fired 10 batches of 5 rounds, going up to the max. recommended load. I was mighty impressed to see the change in group size when as little as 3/4 grain is added to the load.
So, my question is this: From forummers' experience, when working up a load for my No 4 (T) where should my loads start and finish, and in what size increments should I go up?
I use 174g FMJBT bullets and Vihtavuori N140 powder, and the reloading tables Rifle reloading - Vihtavuori indicate a starting load of 38.4 grain and a maximum load of 41.7 grains.
Is a batch of 5 rounds per load-increment meaningful, or do I go back to my best 2 or 3 loads and try larger batches?
Thanks
Rob
