I will chip in on the subject of dies. Full length size every time using a well fitted sizing die.I have been primarily a rimfire shooter as all I had in the past was 100yrd range. A couple of years ago I joined a club that goes out to 300yrs and grabbed my first centerfire bolt gun. Like most I do have AR’s but I don’t shoot them nearly as often as the bolt guns. Paper punching and steel is all I am interested in at this time. I do not hunt.
I have lots of experience loading shotshells in the past and have general idea on what this project will take to get up and operational.
What I am lacking is access to experienced people that have been doing this for a while. I do not mind spending cash on quality equipment. I would rather spend the $$ up front on good equipment than have to re-buy equipment down the road. I know after buying other things and using them for a while I see what works and what doesn't. I am hoping to accelerate the process and prevent buying junk by leaning on others that have experience.
I will start reloading .223. The goal is developing accurate loading for shooting primarily at 300yrds. Eventually if all goes well, I would like to add a 6mm variant. I have Lapua brass that will only be used in reloading/firing in one gun.
Presses:
The basic RCBS Rock Chucker has been replaced by the Supreme that has a slightly different feature set than the original.
RCBS now offers a turret press that looks promising should I want to reload for the AR and am looking for round count and less focused on precision while retaining the ability to operate in single stage mode.
I am not sure if there are better options here or not. The RCBS presses seem to be a solid base to build from.
Dies:
I was looking at the Whidden full length bushing die set but am open to suggestions here. Some say to just neck size when the brass/rifle combination are paired.
Powder measure:
RCBS Chargemaster supreme or some other auto trickle variant. I have not used one of these but the concept seems pretty straight forward.
Annealer:
Still pretty clueless on this part. Some say you need it and some say if you are fire forming brass and restricting it to just one rifle you it’s not 100% needed)
There are a slew of other tools needed (trimmer, hand primer, backup beam scale, tumbler, etc..) but the above items are the larger ticket ones for now. I will be asking a bunch more questions as those parts hit the radar to purchase.
Factory made dies generally resize the brass too much. The neck sizing (bushing) and shoulder bump are within your control but the body diameter is a function of the die itself. Some factory chambers are larger than saami spec and as you can imagine the dies are tolerances for the smallest allowable chamber plus the die manufacturing tolerance plus clearance for the most dirty, hasty application (ARs). Anyway, keep an eye on it because excessive resizing beats up the brass and is likely one reason why some dinosaurs consider *not* full length sizing their brass (just neck size) every time.
Since 99% of sizing does are factory spec this can be tricky and I usually end up starting with a factory die first. If it’s a chambering I am committed to, I shoot a few pieces of sample brass three times and only resize the top half of the neck so it can hold a bullet and then send that brass to Harrells or Whidden for a custom sizing die. Or I get my rifle chambered by a precision smith who has sizing dies that match his chamber. The factory sizing die is resellable and if it’s already used, for very little loss.
