[QUOTE="Michael Eichele, post: 139583, member: 1007"] [b]Re: early pressure with tsx\'s[/b] Dave is right. You are running the 168 Barnes against the 180 AB. The barnes solid copper bullets WILL generate more pressure than a conventional bullet of the same weight. This is why you are using similar powder charges for very differant weight of bullets with similar pressures. [ QUOTE ] what should i expect for a top velocity from the nab 180's with what powder ?? [/ QUOTE ] Depending on the rifle, on average you should see about 3300 with a 180 class bullet in the 300 RUM. That is dependant on barrel length, barrel twist and style of chamber.
