About to take the plunge. With some 155 gr. Lee cast bullets. The questions I have are if powder coated do you still use a gas check? If you did use gc' s where did you buy them? If you didn't use gc's what was your experience? I'm going to try to push these at about 1800 to 1900 fps. Using accurate 2460 or imr 4895. I thinking about trying to hunt with whatever load I can up with and general range plinking.
