Barrel Crown - How important?

[Richard]

Here is an article from the March issue of Precision Shooter magazine. For those not familiar with this magazine? That is because it is not one of the newsstand Shoot and Bang rags. This is the magazine of the Benchrest and Accuracy shooters. The article in this publication are not by the "run of the mill" gun magazine writers who get paid to write basically "favorable" articles about products they get to test for free. These articles are written by accuracy oriented shooters. They get submitted to the editor (who is a benchrest shooter) and has to approve of them; knowing that the benchrest community will definitely scrutinize them if they are not up to snuff.
I had always been of the same opinion, that your crown had to be perfect to achieve the best accuracy............and I still do and will continue keep my barrels with a sharp crown. However, this article sheds a little different light on the subject. I also had occasion to speak with a shooter from Tennessee who holds the 600 yard heavy gun record and has written a number of articles for PS magazine. And........I questioned him about this article? It did not surprise him either? However he, like myself, will still keep the crown sharp.......just because thats the way we were always taught to believe ;D. It will definitely make you scratch your head! Enjoy!

Richard in the artical in mentioned the shell can twist or move in a loose chamber. I thought it would fire form to the chamber before the bullet left the brass then down the barrel. So that it fit the chamber tightly and straight to the bore as it is fired. And could the change in the brass case cause change the BC? Or am I missing some thing?

Have you noticed that when you get a misfire in a ML (where the primer ignites but not the powder?) and the primer actually moves the bullet some distance away from the powder? The same thing in a CF? Just the primer alone get the bullet starting to move...........then the pressure builds!

Thank you Richard for taking the time to share with us all such a superb informational/educational article. I personal found it extreamly helpfull as it lessend my fears as i at least once a range session and often more, smack my crown on my 10ML-II while loading extreme tight fitting sabot/bullet combos and I litteraly cringe and feel sick after doing so. I can usually count on blowing that shot as I am so freeked out about possably having damaged my crown.

Now I feel much better. FWIW I had read similar articles before, but never one so compleately done.

BTW what does a sub to PSM cost? espacially a multi year one?

Thanks,
Arthur.
