Joe C.243: different bullets & same POI?
I have a Stevens 200 .243 1:9.25 twist.
I have Nosler 100 Partition and WW 80 PSP; IMR 4895, 4350, 4064 and 4831; WW brass & WLR primers.
Is it possible to concoct loads from the above materials for the Nosler 100 gr and the Winchester 80 gr so that both bullets will have the same or close points of impact at 100 yards?
Does any body know of any such loads?

hivelosityif you load to match the 100gr to 80gr try and load for the same velocity or slightly faster for the 80 grain. if you have developed a load for the 100gr bullets try adjusting the load for the 80gr and vise versa,

seafire2sure it can be done.. just takes a lot of experimenting is all...
another spiffy benefit of Blue Dot is a lot of guys will find that it offers reduced loads with lighter bullets that have the same POI as their regular full power loads...
But to do so with regular loads, I'd recommend 4350 or 4831 for your 100 grain bullet, and 4064 or 4895 for your 80 grain bullet....
if you change primers tho, at times that can alter the equation, and also if you change bullet brands, that can alter it to..
so if you find a combo the will accomplish what you are desiring.. then stay with it.. and don't keep changing components...

Just because they print together today doesn't mean they will when you have taken the action out the stock and put it back. If you do that be sure to check all loads - quite often there is a slight shift in the relationship.

StonecreekIt will be purely a matter of luck if you can get two different bullets to print to the same point of impact. Manipulating the powder charge, seating length, primer, or anything else to achieve this is a crap shoot. Good luck.
