You're asking someone on an internet forum for their credentials? Well done. I'm obviously the president of the NRA in space, and I also invented shooting. What's more is that ferrets are far more accurate target shooters than humans, but are not allowed to compete at club level anymore, so only a few of us who were lucky enough to be their apprentices have this knowledge.
Happy with that?
If you say so.
My point was that you were portraying your theory as some kind of fact, when you can't see what goes on in the bore and have built a 'fact' around a conclusion, based on a symptom that might not be related, from the evidence of just one rifle - at 25 yards? Come on, there's something else more serious going on if you can get your bullets
sideways through the target in the space of 25 yards.
25 yards.
In one of my posts (#7 in this thread), when the OP revealed that this was happening at 20 yards, I did state that this was a pretty gross.
Your mates 10/22 with a bulge in the barrel is totally the opposite symptom to your pitted barrel. Two examples of not the same thing does not make any kind of statistical pattern.
The symptoms were similar, the ranges similar. No statistical pattern was claimed, but the evidence of just one example proves that it can happen at least once for each cause.

that takes a commonly held belief that an absolutely immaculate crown is a must, and just smashes it. Those blokes went to quite some effort to still be unable to answer the question, and even then they could have been a lot more methodical and the experiment was far from exhaustive. But it proves the point to me that a lot of bollocks is talked by a lot of people who should be spending more time out there shooting and less time talking about it.
I have not claimed that am immaculate crown is imperative. I do claim that a damaged crown can cause inaccuracy. Do you honestly believe that, while some barrels will shoot well with pitting or crown damage (outside of my experience but I am happy to accept the claims of others as possibilities), therefore pitting and crown damage cannot cause the reported symptoms?
There are so many things in shooting that are unproven, but a few people come up with some things that sound plausible (sometimes not even that good) but without any proof or any thorough checking, and it gets lapped up.
I'm no expert, but I try to be methodical and question everything I do because this is a precision game. I
know what I know until someone challenges that knowledge and if it can be proven or backed up then I need to learn from that.
My credentials? I'm a sceptic - give me a sound reason why you think your theory could be correct and why it can't be anything else.
Show me where I stated that there can be no other cause?
...Because it's your theory to prove, not mine.
Not attempting to prove anything, just offering suggestions to the OP
