I have several sets of redding full length sizing dies with bushing for some of my varmint rifles. I just had a 300 win mag built and am wonder what everyone uses for big game hunting guns for dies? I do like the full length bushing dies and I am wondering if a competition seating die is worth getting over the standard seating die? I am also curious if anyone knows what kind of neck tension a redding standard full length die applies to 300 win brass? I am also thinking of upgrading my 257 weatherby dies from RCBS to Redding.
