[QUOTE="David Emerson, post: 1796623, member: 112579"] A parralel throat has a cylinder section of some distance before a 1 degree 30 to 3 degrees sometimes. In other words let,s use a 6mm bullet. I Just looked and the 6 creed has a section of .200 at .2435 before the 1 1/2 degree throat . Now understand this is all throat. Basically no rifling for .2 before the 1 1/2 degree step down to full land engagement. So. Long bullets you want to seat out farther so they are not so deep in the case? No problem. Plus with the long area that is .0005 over bullet diameter guides the bullet to a square engagement and is just a better design in my mind. I once had a 264 Winchester. I took it to a smith and asked him to throat it out so I did not have to seat so deep. GOD did it shoot. The whole bullet was in the bore before it hit the lands so it was perfectly in line. Now I did not ask him to throat it that deep But I got what I got. He screwed up. So that always stuck in my mind. You have heard of Dave Kiff with PTG I am sure. He came up with what is called a bore rider throat. He can set the parralel section wherever you want it. Then a 1.5 degree step down to only half the rifling height that ususally goes for about a half inch then another 1.5 step to full rifling engagement. Usually pick up 100 to 150 fps and shoot very very well and not fussy about oal. Go to Saami and look at the 6.5x300 weatherby. Ed flew up to see Dave and told him I need 150 feet so Dave made a reamer with the bore rider throat. To beat the speed of the 26 nosler.
