IBS anyone?

I'm contemplating trying one of these--mostly cause it's the only thing even remotely reasonable to drive to near where I live. The one I'm contemplating has several different classes; this is the description:

"Each relay in turn will shoot a warm up followed by five scored matches. The meet allows for rifles in the following classes: Varmint for score, Hunter, Varmint hunter, AR (with brass catcher), and any factory rifle with any scope."

What I can't tell is if the only class for the "score" method is used for all the classifications or just the varmint class. The varmint class apparently is ruled by almost exclusively 30BR entrants because of the wider caliber. I don't have one, and while I like the specs of the cartridge I'm not sure I'm interested in investing in a "one trick pony." Does anyone know if the other classes are scored using a different method, and what that might be? I just want to not show up with a different cartridge if everyone is using the same thing.

Maybe the crickets wonder why you would shoot Irritable Bowel Syndrome or whatever that stands for........

Before I posted this the last thread was up for a very long time. I guess the match guys hang out elsewhere? Never seen any mention of the 30 BR here but it seems to be the current darling of moderate range bench rest. It has some amazing chracteristics but I'm having trouble committing myself to building one--it has very limited bullet choice, in fact I can't find any of the special flat base bullets it uses.

flat base, yuch!

i know. i know. short range better accuracy. but isn't that all because of tail steering by the propellant gas?

and don't they usually have more wind deflection, due to lower bc?

at any rate; the open class "any factory rifle with any scope" was for years dominated by 6mmbr i guess now it's 7.62mmbr ;/


as i recall david tub took the trophy one year with a 243ai

If you take a close look at the reviews--it's pretty compelling; very efficient (guys are getting 3000 +\- fps with 110 to 120 gr bullets) and like the 6mm is amazingly accurate and consistent. Also--the wider caliber gives an advantage in scoring where you get credit for breaking the edge of the score ring. BUT you're limited to the 1:17 or 1:18 twist--and like you say the wind does have a big influence at longer ranges. In the event (a distinct possibility) that I don't end up liking the IBS short range scene which is still pretty isolated around my parts, I'm wondering just how useful outside of that limited event these things can be.

Someone's already at worked on an improved version--the 30 BRX.

yeah cartridge of the month comes out nearly as fast as new software.

short (true) story; i run exclusively opensource software, and several years back, when the latest version of "brand to remain nameless" was about to release, i was told by one of the developers, "you need to upgrade to "version" because that older version you are running is junk. this new release is much better."
so i did upgrade... a few months later i was told the exact same thing about the new new release. i asked the guy, "if the one that i am now running was supposed to be way so much better and the one i had before it was junk, and now you are telling me that the one i have now is junk, and the new new one is much better. when in fact i can't tell that the last upgrade gained me anything, why should i believe you about the next one?" kind hurt his feelings i guess, but people loose credibility that way. and when i read someplace all the rage about the latest and greatest new cartridge/bullet/powder/primer/gun design/trigger... pick your poison, i kinda take it with a grain of salt.

are there improvements, yeah sure. but they are usually not as much of an improvement as they are a sails gimic. or that's my openion anyway.

i like things that are tried and true. you can't go wrong with most of them, even if the new car smell has worn off.

Agreed. Though it's pretty easy to see how the shooting competition game drives those refinements; the rules get pretty esoteric and then the experienced competitors are pretty quick in figuring out the best way to excell at the requirements.

Will do--curiosity almost always gets the better of me--and this one has been out a while.
