New to reloading, issues with .223 rounds
 
I just got into reloading about a month ago. .45ACP and .308 are working just fine out of my 1911 and Remington 700 but what I'm putting together for my AR isn't working out so well. The bolt isn't going the whole way forward with my reloads. They also don't come out all that easily when I pull on the charging handle. Takes a few smacks on the buttstock to get them to come out. I made sure that the case goes as far into the sizing/decapping die as it'll go. The bullet is seated to the same depth as factory loads. OAL is also the same as Hornady V-Max rounds. I do NOT have a case trimmer, I'm guessing this might be my issue but I wanted to ask since these are once fired cases. Any help would be greatly appreciated.

I would think as long as the OAL is okay it should chamber, but I trim all of my rifle brass before I reload it so that would be my only guess, trim them down to the trim to length

Are you crimping?

I crimped some of the 55gr since they have the cannelure. The 60gr have no cannelure so I didn't crimp them. I am leaning toward the need to trim. A buddy at work has an extra trimmer he's going to lend me so hopefully I can get it figured out.

Crimping the brass shouldn't matter. I rarely ever crimp my brass.
Are full length or neck sizing your brass?
Is the brass once fired,or from another gun? If so,You need to full length size all of your brass.That can also be an issue,different barrels have different chambers,and if you just neck size brass that wasn't fired from your gun,it can cause issues like your having.
It sounds like a sizing issue or your cases are very long-over 1.760". Most trim the brass to 1.750"
Check the outside diameter of the necks of your brass.They should measure .2532" or smaller,if they measure larger then that could be your problem,or the chamber is really tight in your barrel.
If the outsides of the neck measures are larger than listed,take the sizing mandrel out of your die and measure it.It's not uncommon for them to be a little bigger than they should be.This can be fixed with some sandpaper/emory cloth,and be careful not to take to much off-check the measurement often if your doing this.

This is exactly why I came here with these questions! I did use my digital calipers last night and I know I'm "close" to the numbers you listed but I don't remember the exact values. I'll check them again tomorrow after work and see what's what. Hopefully I can come back and say that everything chambered as they should.

Oh and I forgot to mention, I am using a full length sizing die.

I like to check case length for the first couple of loadings. Brass tends to flow forward in new cases (or stretch if you prefer that word). I also neck ream the first couple of times. Just my .02

Ok, you may be pushing the shoulder back as you seat bullets...Crimping too mush...

OMG, STOP. If you have not trimmed the cases, you may be into very dangerous territory. Over length .223 WILL cause an overpressure that WILL blow our gun up!!!! Back up and start over.
