Thread: Seating depth - who bothers?

Ive just done a little playing around with seating depths.. Reason being, the fathers' loads with softnose projs, go exactly where we aim, as for my lot, same powder weight, same proj weight, though diff shape (150gr SST)... go a little wide off mark..

looking a little deeper, shows the ogives of the projs differ alot - looks as though my SSTs' got a HUGE jump before the lands, whereas the fathers projectiles, are fatter nearer the tip..
ok, start pulling out the proj till we do find the lands...
Can STILL close the bolt on them, even though the cartridge wont fit the magazine anymore.. !
Anyone else come across this? Howa 1500 bolt action. So now, reduced the jump somewhat, (quite alot!), but now go off the max magazine length? Id rather try and stay as close to the lands as possible...
Thoughts?

you can buy things to get just touch overall length or size a case cut down the neck with a hack saw and debur with a needle file and piss round with it till it just holds a pill firmly but you can slide it in and out buy hand.
Do it 5 or 6 times, if length vary wildly its to tight and being pulled back out by sticking in the lands.
Double check just touch with your first 5 or so loaded rounds buy carefully inspecting ogive and scrubbing round with scotch brite(shows the slightest touch)
