Txhillbilly,
I've broken in at least 7 new barrels in the past year. (I lost count. But you can add 8 to the figure if you want to count derringer barrels.
)
The barrels ranged in price from over $400, to $75.
Most of the barrels have been high quality and have impressed me. A few were reasonable, and performed better than expected, for the price.
The most irritating barrel, however, is an E.R. Shaw. It is a stainless Savage pre-fit in .35 Whelen, that I put on a Marlin XL7.
It shoots reasonably well. (~1.5 MoA)
However.... it fouls like no barrel I've ever seen before. After just five rounds, the copper fouling is so thick that you can see the wide, prominent copper streaks with the naked eye, in poor lighting.
If you toss 20 rounds down the tube... It's game over. The copper covers the entire circumference of the bore and is so thick that you can actually see chunks of it stuck to the lands.
Right now, that barrel is undergoing its seventh application of BoreTech Eliminator (a very good copper remover), and I don't expect the patches to come out clean. It's very likely that I'll
still have raw copper staring me in the face after I run some patches through the barrel.
Bad, bad, bad, very low quality rifling, in my opinion....
Buy one again? ...Not likely.
