Does anyone else have a rifle that shoots the first shot substantially off from all subsequent shots? I have a Remington made M40 reproduction that is astounding accurate, but I have to burn one or two shots through it because the first shot is ALWAYS 2-3" to the right. It's kind of a pain, and it's also my hunting rifle, meaning it's usually got a clean bore when I take my first shot at an animal. I shot my pronghorn this year broadside at 300 yards. I was prone with a dead rest and took my time, and I believe what would have been a double lung shot turned into a liver shot with the associated mess.

Back to the point, is this common? I've never experienced it with any other rifles. I understand and would expect a small difference, but not the difference of 2-3" at 100 yards that I'm getting

It's not uncommon.  If your rifle throws it out consistently at least you can learn to compensate for it.  The worst is when it can't be predicted, I've had to deal with that and it sucks.

This.

OPs seems a little on the extreme side, but at least you can adjust for it.

And hey, at least you know what a CCB shot is!

I was a little luckier with my M40 VNC, the first shot from a clean cold bore is 1+3/4" in the 2:30 clock position.

A) You could take notes and use this note to change the hold position on the first shot,
B) You could fire off a few shots prior to going hunting without cleaning in between,
C) You could avoid cleaning the thing until accuracy degrade, then clean it good, and fire off a few shots.

I use A, but I also use C in the low cleaning regime.

Do you clean your rifle after every outing?

I typically run a couple patches through after an outing, and clean every 5 outings or so.

I had a .260 that would do the same thing. CBS would 2-3 MOA higher than the subsequent shots.

Bedding the rifle solved that problem. Difference between cold bore and follow on shots is less than 1/4MOA now.

Just my experience.

I don't believe in cold bore.  I believe in clean bore, but not cold.

I don't advise cleaning barrels anything other than when they need it.
