I've got a new TC Venture in 7mm Rem Mag. Bought a Lee 4 die set and the bullets mentioned above cause that is what I could get . My first pass at loads gave me 1" groups. As ugly as these are they are definitely pretty accurate. I will be using these on South Mississippi White Tails and big feral pigs. The White Tails are no problem but a 350 lb pig is not uncommon. Has anybody used these on heavy game?

I haven't used them but, keep your velocity down to 2300-2400 fps and should work fine. The 7x57 has done that for about 130 years.
