So I just finished reloading my first 40 rounds of 223, now I need to try them out. One thing tho I was wondering if you guys could answer a question for me? I didnt trim cases because they were all once fired cases that were all good. I loaded up 40 and I was trying to get oal of 2.271 but they varied between 2.260 to 2.274. Do they vary that much do to case length? I know 2.271 is long but 2.281 is where my lands and grooves start, so we backed them down to 10,000ths to the 2.271. Does that make sense? Anyway the round is rem cases with rem 7 1/2 primers sierra 55gr 1345 varminter bullets with h322 @ 23.2 gr. My rifle is a rem 700 with 26'' heavy bbl with 1/12 twist.

Re: Just finished loading my first 40 rounds
The length of your brass will not affect your loaded round length. However, I worry about not trimming the cases. Take your calipers and using the thin area of the calipers, measure the length of that brass to make sure their not too long. Measure every one.
2.260 to 2.274 seems like quite a large difference in OAL. You will generally see a small amount difference due to individual bullet differences, but I've never seen .014" difference but I'm sure it possible. What bullets, press and seater die are you using?

I take it the Sierra bullets are hollow point if they're varminters, so his differences may be coming from there. He isn't measuring from the ogive. .014" between hollow points seems reasonable.
Once-fired brass won't grow enough to worry about. Go shoot, have a blast.

They are soft lead point and my bras is once fired and all shorter then 1.75.

Re: Just finished loading my first 40 rounds
I think I found my problem it's the bullets Sierra 55 gr spitzer blitz med vel #1345. I came back out today to try again and re set the die to my dummy case I made and the samething was happening. So I measured 10 heads and here is what I got. 0.711, 0.711.5, 0.712.5, 0.722, 0.713, 0.717, 0.712, 0.714, 0.713, and 0.709.5. I think this is way I have the 0.014 difference in my loads, so what does one do now?

use one of these and measure the ogive instead of the tip of the bullet

You'll have to measure your Case Overall Length. This Dillon Case Length Gauge will help. You just load up your cases not to exceed the case length gauge and you should be good to go.
