I'm reloading for semi-auto's must I use cannelured bullets?

I frequently use non-cannelured bullets to reload for semi-autos. I use a Lee factory crimp die on them and they work fine. I've done this with .223 for Mini-14 and AR-15, .30 carbine for M1 Carbine, .308 for M1A1, and .30-06 for M1 Garand. I've never had any problems.

I have only been reloading for about 5 years now and most of my reloading is for bolt action like you. But, I have loaded for my semi-auto and have used Nosler 150 Ballistic tips and just did a roll crimp. I work with several who reload and they told me that would be okay, just something to hold the bullet in place. Using the cannelure would be better, but they told me that you can load without using them.

You can use a non cannelured bullet but at least with my -06 you should full length resize the brass. Of course every gun is different from the next so you will have to do the trial and error thing to find out.

yes you can, I always have. just watch how much you crimp, if it's too hard you may shorten the lifespan of your brass.

Anyone who reloads for a semi will find out shortly what its like to have a gun blow up. Dummy.
