I am assuming this is for a .243. So, all I can say is I once had a .243 barrel for my T\C Encore. Any bullet that was less than 100 grains would shoot teeny tiny groups using H-414.
Odd part was, when I loaded a 100 grain bullet.....the best I got was MOD...Minuet Of Deer!!
But.....yeah, load up your 87gr. with H-414. It should shoot the eyelashes off of flys at 200 yards easy enough.
Hodgdon's web site shows an 85gr. using H-414 with the Min of 42.0 and the Max of 45.0. I'm not going to tell you what to do, but I would probably start at 41.0 and work up to a max of 44.0 or 44.5 while watching for signs of pressure. But....that's just me and I would not suggest you do that. (Hows that for a disclaimer!!)
