[QUOTE="rost495, post: 65167, member: 1768"] Brian-- Yes that was a typo.... Had to run out to the loading room, measure a handful and come back to the computer..... I know a few that let them jump some. About 20thou or so. I usually just set them so they were 50thou in, but thats probably not so accurate as I'm pretty sure they were basically soft seating at that rate. I always had better luck going at least 35thou in minimum. The chamber had a long throat but was very accurate. Allowing seating the 90 so as to not pass the neck juncture in the case. Barrel life is another thing. I just never got the life from a buttoned tube that I did from a cut tube. Lets say 3500 was probably max for a Pac Nor. While I could run any Krieger to 5000 or more pretty easy. So I don't think you can compare much there in reality. UNLESS you got both done the same way. At that point I still don't think there is going to be that much difference but I could be mistaken. I do like the odd number of grooves lately and will strive to stay with a 5 or 3 from now on. Seems to be easier on everything. I should note that both even and odd grooves shoot fine, for some reason I just have been happier with odd grooves. Of course loading for each is a different beast. Almost like 2 different rifles-- IE could be the same, may not be. Thats my take on it anyway. Jeff Edited to add that I fail to see on seating depth, why folks would seat just to touch. There are very few bullets that are good enough to give the exact same ogive on each bullet(that I"ve shot anyway). That being said its like a roll of the dice. This one touches and pressures are just that. But what about the ones that are actually 5thou engaged, those pressures will be up, and then the other end where you get 5 thou jump or freebore. Those pressures will be down. All that is not good in my books. I know the variation is still there if started off or in more, but seems like all jumping or all not is a more uniform thing than some jumping, some not. Which may somewhat answer why I"m at 50 thou engaged and probably soft seating. I suspect it self governs itself for the most part. BTW this is all funny to me with the BC of the 90. Being able to drive an 80 JLK faster than a sierra 80 due to bearing surfaces(I suspect) and the 80 having a proven bc of 510 give or take, the 90 makes no sense to me anyway... But thats my opinion only. Jeff [/QUOTE]
