shooting with cant questions

[josie6637]

So its my understanding that if you shoot with your gun at a 45degree angle your point of impact is going to be low and in the direction your gun is leaning. How low depends on the barrel sight relationship etc. Is this right? It there any quick reference material for this or calculations that can be done?

For example I shoot a multi ported wall with various angled pigeon hole and slits. From straight up vertical around to flat and back the other direction.
Shooting small targets from 100-300 yds I overthink everything get confused then my heads outta the game.

What's the rule of thumb on this? I have read several threads on 45 degree as well as 90 degree . The 90 makes sense to me but the 45 is like reading Chinease.

Any help on some simple rules to follow on this?

You can enter a cant into JBM. Run a drop chart for cant at 45 and 90 degrees.

I don't know if there is a rule of thumb good enough to hit small targets at distance.

I was also told .1mil for every 5degrees of cant per 100 meters. So it would be almost a mil for a 45degree cant at 100meters. Not sure if that is completely accurate, but that's what I've always been told!

I will try the jbm and see what I can come up with thanks. I will also compare it to the mil suggestion and post what I find, thanks guys

Re: shooting with cant questions

Its pretty easy to figure out if you can just visualize whats actually going on when you cant your rifle. Just imagine your windage and elevation adjustments being a set of x and y axis. When you cant your rifle 45 degrees, you also cant the axis, so the POA would be 45 degrees towards the cant direction. Bullet drop on the other hand always falls down, no matter the cant, so interpret where its gonna hit based on your new axis.
