I run a RCBS Rockchucker. I'm planning on picking up more h322 up this weekend, along with some primers. I want to try something different than the cci 400's I've been using. I'm also going to start using a light crimp, as I have just realized my seating did is capable of this.

I'd strongly recommend against using your seating die to crimp. I tried it before and ended up buckling the shoulders of my cases. When i asked the forum for its wisdom i was told exactly what im recommending now. That's what's nice about the one Lee makes. Its forgiving and not affected by case length in the manner a seating die would be. I still do my rifle reloading on a single stage as well. It makes for a very easy last step.

I also use the Lee crimp dies. Good product.

I'll go ahead and use that one the. I did have it queued up for order..

Are you batching your brass? Or is it a mixed batch? I use h335 and cci 41 primers. The lee collet crimp die is awesome. On the crimping, I crimp, rotate the brass about 25 degrees and do again. It smooths out the marks in the brass. This is especially on heavy crimps. For .223 I only light crimp.

Mixed, I gave up on sorting.

Me too. For my purposes I'll usually take groups that are 1/2 MOA larger to super-streamline the loading process, although sometimes I will sort after loading.

Sometimes, when brass coming into my loading process is already all of one kind, I will load them as a batch..

Is a full length sizing die going to do anything for neck tension? And is a light crimp going to do anything to remedy varying tension? I'm beginning to think some, but not all of my vertical stringing is a result of this.

At this point I'm settling on three loads, two for accuracy, one for speed and fragmentation...
A Varget load works well, as does markm's h322 house load. I had actually found the h322 load in the past, but discounted it for its lack of velocity.
And an AA2520 load for fragmentation, pictured below(25.1), in a 10 round test shoot. This is also where I seem to keep seeing at pesky stringing. I'd really like to find something with a higher velocity, all the while keeping all 10 under an inch.

Anyhow, thought I'd stop by, ask and share.. thanks for reading.

What length of barrel and twist of barrel are you shooting?
