Bore Scope and Barrels

Jim, I used a friends bore scope to check the throat on my 300WM, well holy sh!t the throat was eroded ~1.5" down the barrel with little discernible rifling. Looked bad.

Last BL shoot it produced an 8" 10 shot group.

I think the last few inches of the barrel are as - if not more important than the throat area.

I'm sure this barrel is near the limits wear though with 1100+ rounds and a lot of 5 and 10 shot groups.
 
I have a Lyman borescope I keep shooting until the rifling looks like aligator skin - it is very useful when cleaning though you can see if you removed all the copper
money well spent
 
Personally speaking, I shoot my match rifles until they do not hold acceptable accuracy anymore , but on my hunting rifles I don't care too much. Accuracy is s very relative thing.
I do notb need .5 MOA accuracy on a hunting rifle .
When Mick McPhee rechambered s particular Highwall of mind in a 6.5 Wildcat, he had to cut 4" off the shank to get clean rifling .
That rifle was still shooting 1 MOA at 500 meters before I sent it to him !

I have the one that Ganderite posted about. It is interesting, to say the least, to look down rifle barrels. I have a little old .22lr that seemed to be cooked. Looked down the barrel yesterday with my CHINESE borescope. Rifling is actually in very nice shape. Deaner cleaned it out for me. It looked real bad before the cleaning. The little scope showed that the rifle still has plenty of life left. :)
 
Do you use it to determine how much you need to clean it?
Or judge a barrel by how it looks rather than how it shoots?
 
I bought a Teslong last fall. I cant remember the cost, but it was very cheap. I try not to pay attention the amount of wear it shows. Then i start worrying too much. They all still shoot under moa at 100. and they are all hunting rifles
 
I have owned several rifles with very pitted bores that shot amazing. I currently have an old Savage 219 that has a pitted bore but shoots very well. Cloverleaf group at 50y and 3" at 100, mostly limited by my oldish eyes and iron sights.
 
I bought one of the cheap amazon specials a few months ago for fun, looked at some of the hunting rifles; cool! Then I looked at a Lee Enfield No4 MK1, that's when I put the scope away and haven't touched it since; I cried a little inside.

If only a borescope could tell you how a barrel would shoot....

I bought one to use more out of curiosity than any inflated idea of how well it can shoot. The main problem with my rifles is the shooter! :p Good point!

I was ridiculed when I posted that I had bought a cheap digital microscope. "Child's toy" was one poster's contribution. With that "toy" I have been able to make out several stamps on my "old army rifles", therefore helping to identify some rather important details.
