I don't know of anyone who does in a semi auto.
The problem with soft seating is needing to unload if there is a cease fire.

Oh i gotcha. I didnt even know that was a thing lol. Ive never heard of that. Does it work pretty well?
I have only shot them at 200 yds.. but gun definitely shot better groups with this load with the 1x7.. I got this load from a "long range shooter" at the club.. The Sierras 77s can be loaded to max mag, 2.260 length whereas the A-Maxs have to be single fed...to much a PITA for me.
From what I've read, there are some guns that get the most accuracy if the bullet doesn't have to jump to the lands. My guess is that those are the ones that soft seat their bullets. Others may find that they need to jam them into the lands (and the number I read is 0.015"). But, those who do jump typically only go 0.020".
So, for an AR, we're typically talking about jumping, right? I haven't started reloading for mine yet, but I'm about to (as soon as I sell that T/C .222 barrel).
That whole long jump to the lands, short jump to the lands, soft seat, methods were what I learned and experimented. When I had my own reamer made, I designed it so that short magazine loads were .005 from the lands. I had .040" more I could move the bullets out farther to chase the wear on the barrel, and still magazine length load a 77 Sierra Match king. I am not sure all that work really got me anything. At any amount of jump, a rough leade will hurt accuracy
I have a friend that builds very precise varmint rifles in wildcat calibers. He follows the Roy Weatherby school of though with long led, gentle taper throats. He built a .218 caliber rifle that has OVER one inch of lead! From contact to full rifling is a couple more inches. It sounds absolutly nuts, but you should see the groups he gets out of that rifle.

I have only shot the 223 out to 600 yards. That is plenty far for the little pip-squeak cartridge, I think.
A couple of years ago the USAMU "said" that they were shooting 90's at 1000 yards. Then we found out they were shooting AR10's in 308 secretly across the course.
I doubt that they were shooting 90's. Just a personal opinion though.

It should have been a tomato stake by now
I just don't have my priorities right...
I don't soft seat but instead I bought the RCBS Precision Mic and spent a lot of time experimenting with bullet jump. Everywhere from 0.001 to 0.025". It's very interesting how the variations cause differences in Muzzle velocity as well as group sizes.
As the saying goes - every gun is different.

Consistent case capacity of the brass has more of an affect than does the manufacturer.
Some manufacturers have more consistent case capacity than others.
For the average shooter so long as you use the same make/model of brass it's not going to make much difference. When I'm looking to get started with a new caliber and I'm looking for my first big batch of brass to pickup I get on gunbroker and type in "brass once (insert caliber)" and see what I can get a great deal on.
I've got a 223 that I use run of the mill winchester brass with and shoot out to 700 yards with it. I've also got a 30-06 that I use Lapue (expensive) brass with and it's really not much if any better than the remington brass I've used.
If you get into the highest levels of bigtime competitive types of shooting, then you're going to see the brass become more of a factor, but if you're like me and you're happy with being just under a half inch at 100 yards then normal brass will suit you just fine.

Alright thanks! Ill sort my brass just incase and see how that goes for me.
Actually if you get up near Fort Wayne, I have a big bag full of once fired federal 223 brass that I'd be happy to give you. I'd estimate that the bag has at least 700 pieces of polished brass in it. I reload 223 with winchester brass only, but I came across such a good deal on some federal ammo that I bought some. The brass has a crimped primer, which is another reason why I didn't want to mess with it, but if you'd like it just let me know. I don't want anything for it, I just didn't want to throw it away.
