I am thinking of getting into casting bullets for my 30-06. The plan would be to drive these at less then 2000 fps perhaps as low as 1000 fps for practice and small game. I know that 1000 fps might be to low for the case size but I might use them with a 30 carbine converter.
Bullets are my single biggest reloading expense so I would like to cast.
My question is this. I see lots online about cleaning very well when switching between cast to jacketed and back. How important is this?
The Idea would be to shoot maybe 5 rounds of full regular reloads and maybe 20 rounds of very cheap low velocity practice ammo at the range in no particular order, with no cleaning in between. Will this cause problems?
If I need to clean in between then it would not be worth it.
