Thread: bearing length

True but you would expect a .270 to shoot 130gns, a.308 150's a .300 180's etc as they are bread and butter for the calibers. not radical very heavy or light for caliber bullets. I would have thought 160-162 would shoot in a 7 mag and maybe when you get 175-195 things might need to be accounted for like faster twists and maybe bigger cases to get the most out of them. I did see on another sight someone mentioned the more bearing surface the faster the twist needed. He believed thats why some of the bergers will stabilize using standard twists even though they are heavy and long for caliber. There bearing surface is shorter. Food for thought but needs more people to measure and record what works well in their rifles to see if there is a pattern I guess
