nanuk-O-da-Nort,
Absolutely not, what I was trying to say that my seating tests on the .221 paralleled exactly what hornady portrays in their manual...As far as Hornady took them that is...
Hornady only showed velocity and pressure decrease in their illustration...And they inferred a co-relation in the test between the two...
My seating depth tests went through the whole gammit from .005 in the lands to "on" the powder, where velocities started increasing slightly as you should expect them to do...
I know that velocities alone do not indicate pressures and I do not have any pressure testing equipment but I am not one to argue with the laws of chemistry and physics..
Obviously as I stated earlier Hornady did not even try to emphasize these minor insignificant changes on that end of the spectrum but only the more drastic pressure jumps when the bullet is seated at,near or into the lands....
Their demonstration showed the effects of moving the bullet away from the lands and pressure & velocity dropped significantly this will always be true...
Without perfect test conditions yesterday( -7 deg F) I tried this test in a 6.5-06 that I just put together and am starting load development on..Same charge of h4831 same bullet berger 140 vld .010 into the lands 2912 ave mv,
.010 off/2888, .030 off 2871, .045/2853, .065/2855, .085(just on the powder)/2869, .095/2871(slightly compressed...Not near perfect test and only three shot strings but a trend one would expect...
Sorry if I confused anybody.
