I just got back from shooting my tikka t3 lite 22-250. I shot three different loads, rem. umc 50 gr. jhp, win. 50 gr. silver bt, and federal 55gr. nbt. The remington umc round shot .5 inch groups at 100 yards. Has anyone used this round on coyote before and if so, what did you think? Also if anyone can help me that has the software, I have got my tikka sighted in at .75 high at 100 yards with the 50 gr. jhp. What would be the trajectory from say 50yrds out to 300 yrds.? Thanks.
