Over the years we have had, read about, and seen Great Barrels.
Question, have the barrels we shot been, some much better than others,OR, have some been chambered better or worse?
In match reports we notice some barrel brands mentioned more than others, AND, we have noticed some gunsmiths mentioned more than others. Is there a relationship?
Notice that our top shooter of all times,TB, over the years has sometimes changed both.
So???
Since I chamber my own barrels, I suppose I can say that the "Gunmithing" has remained consistant through the 20+ years I have been involved in Competitive Benchrest. I look at barrel work the same way I do any other Machining operation. You check and verify everything.
Through those years, I have had barrels that were certainly a cut above, so to speak. But since about 1999, I have shot nothing but Kriegers. The reason is they are very consistent with their groove diameters, and they generally keep the lands within a "tenth or two" of what it is suppose to be. This goes for both their 6mm and 30 caliber barrels.
Some do shoot better than others. I have no explanation as to why. I used to put great pains into ascertaining why some barrels shoot better than others, but now, I just chamber them up and let the target be the deciding factor.
I have actually given barrels away that I thought were sub par, only to have the Shooter I gave it to come back and do quite well with it.
Some years back, a notable shooter bought some used barrels from another very well known shooter who said up front that he could not get them to shoot. One was a Unlimited Krieger. The shooter cut it off, rechambered it, and it was a winner. Possibly one of the best barrels I ever saw. Go figure.
One other aspect of this is the bullets we shoot. I am beginning to believe that you have a better chance of getting a "great" barrel than you do "great" bullets. Keep in mind, all of the top Bullet Makers make VERY GOOD bullets. But, for what ever reason, (they are at the mercy of their material suppliers), we sometimes get a Lot of bullets than simply seem agg better than another, even though upon visual inspection you can't see any difference.
Back through 2005 through 2008, I had such bullets. Anybody that has been around the Gulf Coast Region that long knows how good that particular Lot of bullets was. When I ran out, my shooting suffered.I did not suddenly forget how to shoot.
Some shooters keep multitudes of different brands of bullets on hand so they can find what a particular barrel likes. "Feed the barrel what it likes", so to speak. Many of us tend to stick with a "tried and true" combination that we know is competitive, and just chalk it up to bad luck if a particular barrel, or Lot of bullets, doesn't live up to our expectations.
For me, Short Range Benchrest has always been a crap shoot. You put your coin in, pull the handle, and see what come up. If it's lemons, then you stick another coin in.
