What is the optimum spacing between the barrel and the scope? Right now my scope clears the barrel by about .25". I have seen people with less gap and others with more gap. What do you personally prefer?
 
Re: Scope and barrel gap

Not touching.

For me, it depends on the application. I don't subscribe to the "as low as I can get it" book for all scenerios. For hunting applications, I prefer to shoulder the gun with the scope on the upper power and the eyes closed. When you open them, you should be looking through the center. If not, get different rings. Everyone's built different, so you can't paint all with the same brush.
 
Re: Scope and barrel gap

I prefer my optic as low as possible without touching barrel. The less scope offset the better in my opinion. I do however run an adjustable cheekrest so it allows me to correctly set up the rifle for my "chubby cheeks" while giving me the proper eye relief.
 
Re: Scope and barrel gap

I like for the scope to be as close as possible to the barrel. I like a small gap between the butler creek cap and barrel. I have found that with most 50mm scopes and a stock pack this offers a nice cheekweld.
 
Re: Scope and barrel gap

Most important is that it is low enough to be able to get a good check rest position. Otherwise the exact height does not matter that much. For me, I like to have it high enough that I can clean with a cloth under the scope and my barrel without removing my optics, but not much higher than that.

If I can see light I'm happy.
Shoots in the 3's on a great day as it is (usually I shoot MOA or a little better, but its me, not the scope touching):

In some cases lower is not always better. Case in point: IOR 3-18x42mm mounted in 35mm TPS Extree Low rings, and an AICS 2.0 stock. If the scope was any lower it would be unusable. The adjustable cheekpiece on the AICS is set at it's lowest position.

But birds could nest under the objective end......

Don't forget to put objective diameter into the question.

A 42mm obj in a .84'' high ring will have a bigger gap to the barrel than a 56mm obj in the same ring even though the bore height is the same.

Sounds like you have some high rings on your setup. Most scopes on a bolt rifle can be mounted with a 0.885" center height ring and have enough room for a BC cap.

I have read about people milling the bottom of the cheek piece so it can be adjusted lower. . .
