Just picked up my 243 1 in 8 twist barrel and was looking for views and info concerning the redding type s full length neck bushing die, is this die a adjustable neck sizing die and would it be best accuracy route to go in a 243 with Lapua brass and 105 molly scenars, also would a forester benchrest seater die be a good bet with necked sized Lapua brass and thread into my rockchucker press with rcbs shell holder, thanks for info and help paul T.
