Thanks, guys! I'll let you know how they turn out.

I tried to go "here", but all I got was an error message. Could you be more specific?

I have a Sig Tac #556 (.223) that I want to start reloading for. It has a 1 in 7 twist rate and a 16" barrel. I'm just shooting at paper at 100yds or so, and I can't find any real data for reloading. I want to go as cheap as possible, because this is just my "fun" gun. The only cheap bulk quantity bullets I can find are the 55gr. FMJ thru Cabelas, so I would like to use those. I'm also planning on using Remington 7.5 primers due to their hardness factor. Anybody have any good powder suggestions and data I can use to push thru my Dillon 650? Thanks.

What will you be using the ammo for? Cannelures are for crimps, but you do not need to crimp just because of a cannelure. You can also crimp a non-cannelured bullet, or not. I shoot a match AR and an AR varminter. For the match rifle I cannot get the long range performance I need with a cannelure. For all day blasting of PDs in the varminter, cannelured el-cheapo bullets are fine for close range shots out to around 150 yds or so. I use a bit heavier bullets for the longer shots, without cannelure. Hornady V-Max are great for PDs, and paper punching. 223 bullets are .224 inches in diameter. More info on the rifle you will be using with twist rate would be helpful in choosing a good bullet for your application.
