using factory loads in 100 gr 243 bullets, i get 1.5 inch groups at 100 yards. using imr4350 powder and speer 100 gr spbt bullets, i am getting the same grouping. rifle is remington 700 and not shot a lot so throat should be ok.
in trying to get the oal of my reloads, i used a fired cartridge and a bullet in the case and loaded the empty round into the rifle and ejected it and measured the length. did this with two separate cases.
the bullets were pressed into the cartridge shell and didnt come close to the cannelure. here are the measurements of the ejected cartridges.
oal 2.65
case length 2.054
the bullet needs to be seated 0.0638 - 0.0640 deeper to reach the cannelure.
even if a crimp is not used, it seems that the bullet would have to be seated really far out to get close to the lands using the 100 gr bullet. doesnt seem to be a lot of bullet left in the neck to hold it, even tho it is less than max oal. would seem impossible to do with lighter bullets which are even shorter.
how can the bullet be seated closed to the lands if the bullet is seated properly to crimp on the cannelure?
advice or recommendations would be appreciated.
thanks.
