Re: Talk me out of a 30-338.??

Just one word of caution when chambering your guns throat. You need to have a good idea which bullet you are looking at using. You will find there is a substantial difference in Sierras and custom bullets such as Bergers and JLKs when measuring the length of bearing surface and base to ogive. In my 6.5 there is a .112 difference, which means with my present chamber, the JLk base is actually seated up in the neck to be in the lands, while the Sierra base is down in the case. Measure several different bullets (can use two Stoney Point comparaters on caliper) to get bearing surface or base to ogive lengths. Discuss with gunsmith and he can throat possibly inbetween to allow both to be used.

Re: Talk me out of a 30-338.??

Hey Fellas.. I ordered the reamer back in October and asked Dave if he would set it up for Norma 338Mag brass and Nosler 180BT's to Sierra 200 something's with a "clean up" neck.. He seemed to know exactly what it is I wanted so I'm gonna go with it..
.. Thanks for the positive report on the Lilja 3 groove.. I've heard great things pretty consistantly on these barrels.. I was a little worried with the 11 twist.. Also, since Mr Lilja's article was the instigating factor in this whole thing,I thought it would be rude to go with anything but a Lilja barrel..
I had some dealings with Jimmy Knox on a 22-250AI fast twist project and he was great to deal with.. Maybe more dealings are forthcoming..
..The new WSM cases are extremely interesting.. I'm leaning t'wards the 7mm version tho'.. First I'm gonna wait and see whoall comes out with the brass.. It would severely chap my buttocks to get a reamer to Norma or Winchester specs only to have Lapua making it a week later.. [img]images/icons/mad.gif[/img]
daveosok.. Linky no worky..
..With what little data I have available to me the 30-338 was very close to the 300WinMag in velocity across the span of bullets I'm currently interested in using with a little less powder(for whatever that's worth.).. Logic being also that this is one of the smallest of the "big magnums" and if it fails to meet expectations a re-chamber to a more obnoxious cartridge is only $140 and a month waiting away.. [img]images/icons/grin.gif[/img]
..I do like the idea of the plentiful selection of brass, dies and other assorted "goodies" for the ever popular .300Win.. And you're not the first BTDT individual to suggest such.. One-of-these-days us hard-headed upstarts will listen.!! [img]images/icons/smile.gif[/img]
.. Thanks for the heads-up.. But this gun will be something of an Unlimited if I ever decide to try a little organized competition.. The .260AI Viper w/27" HV is for light gun.. I'm thinking some casual competitions at the club will peak my interest a little more than regular BR.. If I get all this mess loaded and moved the highly likely scenario of shooting a few sighters and a couple of groups then being "out of it" is somewhat unattractive.. For the effort involved in transporting this gear I wanna do some serious lead-lobbing.!! [img]images/icons/grin.gif[/img]
..If you have any real world shareable data on your 300WSM I'd like to check it out..!! I bought a bag of Winchester brass a while back and have been checking it out a bit.. Can't say as it's very good stuff but the design is schweet..
..Hopefully Dave really does know what I wanted.. We'll see..
Izzat enough from me ya think.?? [img]images/icons/grin.gif[/img] [img]images/icons/grin.gif[/img] Thanks all for your input.!! JiNC
