Hiding and lazy?? Or not willing to publish a reamer print specifically because we get "I want to use your chamber for <insert the wildcat name> but I want my gunsmith to do it" It's exactly what
@BLKWLFK9 said above: people want to use someone in particular who doesn't have the experience or knowledge base for that wildcat so they ask me to hand them information for free knowing full well they're not going to contribute anything to the effort and costs that went into gathering that data. I know that "tight" and "match" chambers are full of issues. Figuring out what needs to change and what doesn't from SAAMI is a critical skill for custom rifle makers. Publishing that information and data is free education for your business competitors.
OK, have your gunsmith figure out how to make a 22BRA with the appropriate throat and neck dimensions that it runs well for a full PRS match weekend, plus zero day without generating a carbon ring in 300 rounds, not overworking/splitting necks, not blowing out case webs, avoiding feeding issues from chambers that are too straight/improved... Have that gunsmith buy a box of each different 6mm BR brass on the market, slice it and check sizing trends. Check the neck thicknesses and buy a bunch of the bullets that people MIGHT want to shoot in the case and measure those.
Then get on the internet and take that data gathered from several hundred dollars, closer to $1000 worth of stuff, and half a day's time and publish it for free. Specifically so someone on the internet doesn't say "you're lazy and hiding stuff" If it's so easy to get the data then get the data yourself. But it's not or the entire complaint would be moot...
I spent thousands of dollars in ammo developing reamers specifically for popular ammo choices within the 6 Creed, and 6.5 Creed, and 308 Win market. The PRIME website had numerous posts from customers bragging about how good their PVA prefit shoots PRIME ammo. I got numerous calls from gunsmiths asking for the print. Usually for free but some were willing to pay "a nominal fee".
Why? If the information is so easy to get themselves, why offer to buy the print? Because the performance sold product. That work wasn't free to do, why should I give it away?
People call and ask me what speeds and feeds I am running on reamers, what's my setup look like on my CNC's to cut barrels the way I do, what does my setup and programming look like to contour barrels on a TL1? I am supposed to give that away for free too? Maybe Speedy Gonzales' gunsmithing class DVD's should be free?
Where does it end? The techniques aren't patentable, so how do you protect them? Don't talk about it, don't publish it, don't give away the secrets.
Draw a 5 mile circle around my shop and there are at least 15 pizza places. I know 2 that are excellent, 3 that are decent and 1 that absolutely SUCKS. Nobody is sharing recipes with each other and if I walk in and say "Hey can I get your sauce recipe so I know you're making it right before I order" what do you think is going to happen?
Pepsi and Coke don't share recipes and those global companies have virtually unlimited assets to figure out what the other is selling... yet we have Pepsi and Coke with distinct flavors.
Too cheap to replace a reamer?
Too lazy to look it up?
Get real dude... my bill with the reamer grind shop last month was over 6 grand. We average 65k a year through the place that grinds my reamers. You're so far off base it's laughable.
It's not my job to educate and provide data to business competitors. Some of it we do supporting our products and services. Teaching people how to assemble a rifle from a box of parts is something that naturally comes from troubleshooting things that aren't shooting. There are a bunch of gunsmiths who offer a class on how to do basic armorer level work (swap a barrel, mount a scope, swap triggers) for products after they sell them to the customer... yet you're going to accuse me of being lazy or hiding something because don't publish reamer specifics on wildcats that people flat out tell me "I want your reamer print so my gunsmith can order one".
