I've been perusing the Graf's catalog again, in prep for a bulk purcahse of bulelts and brass. I noticed that the Winchester and Remington FMJ bullets are a lot cheaper than the Speer FMJ. I also noticed the Speer is listed as FMJBT w/cannelure. DO the others NOT have cannelures? I've never seen surplus ammo without cannelures, but do they actually make commerical ammo as such? The other question is, will the more expensive Speer fragment like Hirtenberger will?
