5.56 62 gr xtac weapon zeroed at 50m   What's my drop at 200 m

Depends what you're zeroed at. =P

For straight line drop, you'd have to either chrono and calc it, or figure -50 fps per inch of barrel loss from a test gun with posted results using that same ammo. That'll give you a very rough table.

Should be none with a 50/200 zero.

I don't think that totally works with anything other than the weapon and ammo selection intended. I don't know how close it is either.

Besides, it'll still be high with a 36/300yd Z.

I have my 10.3" zeroed at 50 yards and I have the same POA/POI at 200 yards using the same ammo(Wolf and Tula).

YMMV

Just finished a 10.5 and this is good to know.

That ammo is known for being underpowered even for 223, and is likely the 55gr?

So a full power 5.56 rd will do other things. Especially if you change the bullet weight to 62gr I'd think.

My local range is undergoing a big move. The old range can't be used, and the new one isn't open yet. I've had to start on a 300yd range on my property. I have all my spots for target boards marked out, just need to get the boards built and put in. When I do, I'll know how accurate the 36/300yd thing is with a 10.5". Not with junk ammo though.

Indeed it is. But I have only shot that out of the pistol with the above results. It would differ if I were to shoot some 193 out of it, but I zeroed for what I will continue to shoot.
