I have a reddot that covers 3 inch at 50 yards.3.5 inch black bull,makes some pretty good alignment.the rcbs 200,easily shoots under 1 inch,,im very impressed.gun will run from 1600,and ive just been over 2000,,with 4227.
1600-1700 shoots tighter naturally.
I was able to shoot 358156 today as well.
2400 loads...1500,wont eject neither will 1600,,but dont they shoot tight!!!
It will start to run over 1800,,around 2000 runs good,but started shooting buckshot patterns.even with thegas check,,it aint happy kicked in the butt.

I bought this foolish rifle to play with,,should keep me entertained, for the summer!

Got the rcbs 200 to about 2000fps today,with h4198sc,,no signs of pressure.
I noticed at this speed,,the cases eject 5 feet forward from normal.must have something to do with how fast the bolt opens.
These ar,s are kinda neat! Been avoiding them for 40 years.

Over gassed . It means the pressure at the gas block is too high . It can be reduced with an adjustable gas block or compensated for with a heavier recoil buffer, or more spring tension . Unfortunately too much of any one messes with the balance of the system and will have you chasing ghosts .

I had a situation with 4198 being in an awkward place with too much pressure in the case to release and not enough to pull the case out in the gas tube and it got worse as I increased the load . It would feed and eject fine but miss the hold open at best holding on the follower . H322 fixed that but also took it from good hunting groups inside 150 to "yes that'd work to 150 but not for me" . Moving from the carbine gas length 16" to a 20" rifle gas fixed the gas issues with 4198 and added 200 fps MV . Shifting to a 5r heavy barrel didn't hurt anything either.

Brass , well balanced, should eject @ 3-4:00 . Forward of that and it is being thrown forward by the bolt return and the bolt hitting the brass and or even starting forward before the spring ejector can get the brass clear . Behind that is slow bolt and may have mouth dings from hitting the port before it clears.

Sometimes brass transfer to the deflector boss will refine a search for body dings , if it's there you have a slow/delayed/under gassed situation if not it's from the front side and bouncing off that end of the port . See over gassed/too much bolt speed .

A band aid from the cheap seats is to select a washer that will fit the tube ID and clear the buffer stem OD . It can be placed at the bottom of the buffer tube to increase spring tension if you only need a little bump or over the stem to both increase spring tension and buffer weight. A word of caution you are working with sloppy but none the less clearance you can't add more washers than you have spring coil clearance as that will cause a hard stop situation .

Forgot to ask,,over gassed....the brass looks good,is it hard on the gun?
It runs well,,so,other then battering the gun,,why would i care where my brass landed?thanks,

I'd go with an adjustable gas block and just turn down the gas a little if you're happy with the load. I've never been really sure how to interpret ejection patterns with brass which is significantly different in shape, size, and weight from the cartridge and gas setup that the system was originally designed to work with.

I got one that slings 500 grain bullets. As long as the brass ejects I don't care where it goes.

Im gonna be trying the new to me 35875 bullet in my Legend Bolt.
I have a great load W/Bluebot and a 220g MP bullet also Blue Dot under a 180g NOE bullet shoots really well but its only 1400 fps.

Once i get comfortable with this thing,im gonna break out the plain base bullets.
Gc is a pain,and added expense,but the bore is shiny,,not a fleck of lead in the bore!

This gun is a ruger,with muzzlebreak,,bunch of holes,,,there hasnt been a sign of lube smear,in the holes,,i would have thought the lube starts flinging right after the crown??

you'd think.. LOL
doesn't always work that way.

it doesn't always come off in a spray...
sometimes it comes off in bits and globs
sometimes it don't even come off when it hits the dirt.
sometimes most of it's gone before the bullet even gets into the barrel.
lube viscosity, ambient temp, lube makeup, wax type, powder timing, residual muzzle pressure, gas cutting, skidding.
they all help hurt.

223 and 6.8 not 350 .
The H322 I think has a moderate rise and steep drop off while the 4198 has a slow rise and flatter curve .

The AR isn't especially hard on brass that I've seen in the traditional stretch and form way but it does tend to beat up the brass on the way out . Feed ramps can be hard on it also but most of the "better quality" (you pay for the final finish) are pretty smooth .

Tomes of reading applied to a little bit of experience.

Ejection pattern does not always mean over gassed. Powder speed plays more of a roll than an oversized gas port. The powder you are using just has a higher port psi as it is a slower powder.

The easiest thing to do if you are going to keep using this powder is check to see which buffer came with your gun. A H2 will be what you are looking for if that is not what is in it. That won't void your warranty if changed like a gas block will. You may have to weigh the buffer to figure out which it is.

I was hesitant to buy anything new anymore,but i took a chance on this ruger . maybe i got lucky,but i must say,this barrell is super high quality.it is as smooth as a handlapped custom barrell,from one end to the other,very impressive!

I was SHOCKED by a Savage Axis barrel I picked up a few years back. This was cheapo version. Dosent even have the dingus trigger!!!!

But first cleaning I was LIKE WOAH!!!! GLASS SMOOTH!! And let me tell you right now WELL
UNDER MOA on a 359$ 7/08 WITH A SCOPE!!

I loaded a few different loads ta try EVERY ONE shot touching holes!!!!!! 120g varmint 139g Hunting and 150G match shot as good as ANY I have ever shot!!!!

Sometimes a company JUST GETS IT RIGHT!!

I dont think ive ever heard of a savage that didnt shoot well.
I bought a 7-08 for my first son,,,cheap,ugly,clunky,mod 11,,never bedded it,but that thing shoots 140,s as well as any 700 rem ever did!!

Noticed todays shooting,,the 4198 loads throw brass at 230-300 oclock.
4227 loads throw em at 4-430,,, both loads was about same speed.i find this stuff intresting.
Also,,got the 200 rcbs almost up to 2100 fps,,runs perfect,no pressure signs,,and under an inch,at 50yards.fun time playing with this thing.
