I actually wrote to them for load data but nothing so far
Do you have a source in Canada? I only get GAS Customs through the USA and that gets spendyI've loaded their bullets allot, I would use the starting load for the 300 grain Tsx and slowly work it up. They are an extremely low pressure design.
Here is my loading data using the 300gr Barnes and Hornady
300gr Hornady and Barnes TSX COAL 3.540
H4895---ADI2206H
77gr.......2633
78gr.......2695
78.5gr.....2683
79gr.......2700
this load has been deadly on elk size game and an honest 300+ meter round. Using the Hornady 300 at 2700fps has become a favorite varmit/pest load as it turns everything into a grey mist..
You could try cast bullets, too.
I have read that a plinking load for the 400 would be to use .41 caliber pistol bullets. Does anyone know how you would start to build a load for this? The grain weights are not comparable to anything I can find.
Trail boss sounds really very good. I will pick some up for sure.
I also read about using pistol ammo in 41 mag as plinkers but have no clue how to do it.
