I\’m looking to keep my SD as tight as possible as I am loading these to run subsonic on my 4\” Walther PDP and 8\” AR9. I\’m looking to get as close to subsonic as I can with the AR9 to get the max velocity out of my PDP. That said, I am having COAL variances due to inconsistencies in the Nuke tips. Should I be using the rounded seating stem meant for ball projectiles? They do leave a slight cosmetic ring and I\’m wondering if that\’s a more consistent location to set the seating dept since the flat seating stem would cause variances in case volume.
Thanks.
I have seen reloaders modify a seating stem by using JB Weld or similar. They add a dab to the tip of the stem and press the bullet into it to create a custom stem after it cures. This helps to make better contact with the stem.
Another thing to consider is brass capacity. Doing thing like sorting brass by weight and headstamp can help with lowering velocity deviation.
That\’s an interesting tip I never thought of. I guess my next question is would the ogive be more consistent than the tips of these NUKE projectiles? I could modify a ball seating stem to press against the ogive with a bit more surface area to reduce the ring it leaves right now.
I am usually reloading with my once used factory brass so the head stamps are usually the same. I\’ll be using the other range pickups for plinking.
