I hope someone can help me here - I dont understand the concept of using a 22-250 for shooting foxes and it deemed a barrel burner.
How many foxes are being shot in a night and over what time period would heat a barrel up? 10 over 3 hours? Just trying to understand...
I appreciate it may be more powder than a .223, but in the grand scheme of things, its similar or less case volume than a 6xc (I know the original parent case of the 6mmxc was the 22-250), 6mm creedmoor, 6x47 etc. The 243 has a bigger case volume again in the world of 6mm...
At the end of the day, if you are spending more time plinking, range time, testing, long range, practicing of various other forms of shooting, there are other cartridges that suit a higher round count per barrel than a 22-250.
If your intention is to shoot 5 or 10 or 15 foxes in three or four hours over the night, I would suggest its round count that will be less that a 223, but it may be the case that you have better results with a 22-250 - like I did.
My orginal choice of 223 on deer did not give confidence when I started out, but the switch to 22-250 was a game changer for the good....
My last comment would be, most rifle barrels are damaged by lack of care more than round count....
