Yep, a stock barrel is going to put some really nasty smilies on anything you stuff in the mag.
The jury's still out on what effect it has on performance; what the real question is, to me, is whether the bullet can be driven back into the case far enough to cause a case rupture from increased pressures.
Doing the Smiley mod isn't likely to affect reliability in any way... the area that's worked on isn't close to where the bullet begins it's travel into the chamber.
If you do decide to do a mod, they're detailed in the Articles section on the Home Page.
