Some health issues are keeping me from tree stand hunting this year so I’ll be sitting over cut corn and beans with my 50cal CVA Optima this year. I am looking for a bullet/powder combo that will do well on big whitetails out to 250yards. I’m currently using 777 loose but not sure its got the velocity i need so should i go with blackhorn or white hots? Also currently shooting a 250gr Barnes bullet.
 
Your powder is fine and so is your bullet (with a sabot?). You need to start a load at about 70-75 gr. of 777 and check for accuracy. If that load isn't up to your standards then increase it by 5 grs. Do this until you get a 3-shot group that is accurate at the yardage you will be hunting.

Then go kill that deer. Good luck.
 
I’m trying the new Hornady bore driver ELD-X this year. In a CVA accura LR-X. So far, it seems to be liking 100 gr (by volume I should add) of BH 209.
I’d think your combination would work fine, but the drop at 250 would probably be significant.

Before i switched to a smokeless muzzleloader i was running 70gr by weight (which would put it just under 100gr by volume.) Of 777 behind a 325ftx in a .458 sabot. I dont remember the velocity off hand, but it held about moa at 200 and corresponded with the fat part of the duplex of my scope on 7x.

Shot a nanny goat at 170yds which is the longest shot ive made with a muzzleloader.
 
Using a CVA Accura with 80 grains of loose 777 under a sabot and 45 cal 255 grains, lee, soft lead RNFP bullet. works great at 100 yards and did not test it to 200 for drop as I only have one spot I can shoot that far and I usually only bow hunt it as it is a hole in the old cattle fence that works as a funnel. Muzzleloaders probably shoot like artillery at 250 yards, I would assume and have not tried it.

[EDIT] A little google fu and I found something someone posted after sighting their ML in at 50 yards. So if sighted at 100 yards you got an 18" drop at 200 yards. 250 yards might be off the scope or the very bottom and it is slumping off fast from 150 - 200 yards
25 yds = ~0
50 yds = 0
75 yds = -0.25"
100 yds = -2"
125 yds = -3.75"
150 yds = -7.5"
175 yds = -12.75"
200 yds = -20"

If im remembering correctly my gun was 3-3.5" high out to about 100yds then dropped to about 10" @200yds.
 
250 is a long poke. We used to shoot BPCR at 100 and 200. My 45-70 with a 380 grain bullet and 60 grains of fffg dropped 24" at 200 from a 100 yard zero. Aperture sights. I've not shot ML beyond 100 other than an ill-fated attempt at 200 with a musket at the NMLRA nationals.
I personally limit myself to 150 with my 50 cal, 270 grain Bore Drivers and 90 grains of BH209. I hate wounding game and at almost 80 hate tracking very far even more.
