Advanced Marksmanship First time using a can. Will my DOPE adjustments be predictable?

[nikdanja]

I have all my data I need for my rifle
To hit at 700 yards. I know putting a can on the end will mess with my impacts but will it be predictable? Example, I will always hit 1.5” low with my can. Therefore I need to make 1.5” worth of adjustments on all my distances.

Also, will I need to work up a new load due to the harmonics being different?

One time adjustment for your 100 yd zero, then same adjustment for distance(s) as it has always been.

Depending on the can, it may also add some fps to your MV. At very long distances, you may have to account for that as well.

This! There is .2 mils difference in my zero from can to no can. Know it, adjust for it.

A match in Illinois. 2 shooters came with suppressors attached, but they are illegal in Illinois. So, they took them off, rezeroed, and both said their rifle shot 3 inches higher at 100.

Really no reason to re-zero them but whatever works...
