I have begun to load reduced loads for my 22-250 Remington and am wondering if there is anyone out there with experience that I could learn from. My objective is to end up with a good cartridge to use in the field for preditor hunting.
I am following the load data table of the Hornady manual for the 55 gr fmjbt bullets. By memory it calls out IMR-4729 power in the 14 - 17 gr load range. This is basically half the weight of a standard 30'sh gr load of IMR 4895.
What I am curious about is the advice on using a filler material to get the case volume filled. I understand the concept of using filler materials is to keep the powder uniformly in around the primer so ignition is consistent. Any comments on pro & cons of filler materials would be appreciated.
For example: Would I be taking great risk of I did not use fillers? Would using fillers and bouncing the cartridges for hundreds of miles on my snowmobile mix the filler & powder? What filler would be recomended? ECT...
