i have a direct thread 30 p1 and was thinking about running 55 gr subs, should i be concerned with a possible
baffle strike? btw its a bolt gun.
also should i worry about carbon build up when putting it back on the 30 cal?
 
its got the twist 1/8 , but i have a bunch of 55's and dont want to use the better bullets for plinking sub loads.
seems like it would be a waste of good bullets. i can practice at home to 60yd's and it seems like a fun way to
form brass to my chamber for future neck sizing.
yes i could use a 22lr but i'm silly like that:).
just really concerned about a strike.
 
Out of pure curiosity, why would you want to shoot 55gr subs?

You get .22lr ballistics and suppression without the need for a 22lr conversion kit and the mess associated with shooting 22lr in an AR.

I've worked up 62gr loads with Trail Boss and there is no issues with 1-7 twist (your mileage may vary). VERY quite and accurate.

Have you fired full speed through it....its still pretty quiet.

I shoot 204 ruger through my much crappier 30 cal can and its pretty quiet.

Yes, it's quiet but no where near as quiet as subsonic. Subsonic is movie quiet.

Only drawback in an AR is it will be single shot only. 22lr conversion kit suppressed will cycle conversion kit.
 
The conversion kit cycles the conversion kit? You don't say..... ;)

I know right. I'm not sure if you'd call it a tiny bolt....lol

But 60gr SSS is very accurate and movie quiet in my 10.5" w/AAC Ranger 2. No POI shift to speak of. I just don't like shooting 22lr through the can. (Dirty)

Sounds like an expensive way to shoot 22lr basically. Youre going to need a different buffer, and gas block if not opening your gas hole too. I'd spend a few more bucks and get the conversion and be done with it.

60gr aguilas run awesome out of my AR witj the cmmg conversion kit and my sparrow hanging off the end. Quiet and hit dang hard for what they are.

Couple rounds of full power 223 clears the gas tube out just fine. I just dont get the point of spending 5x the money to shoot 223 subsonic.
 
I've used 55gr fmj's with ABOUT 4.5gr Trailboss if I remember correctly. I don't have access to my data right now. I think 4.5gr is right around the point where some went supersonic and some didn't. POI is like 11" low from a 100yd zero with a 16" 1/9 twist bbl.
When you check for good stabilization, check it within a foot of the muzzle. I do this by setting up cardboard right in front of the gun, another piece about 25 yds and finally 1 about 50 yds. Line them up and shoot through them all at once, making sure you get nice round holes. Only after testing good with several rounds do you install the can.
I have only 1 can, a YHM 7.62 QD Ti. Works very well.

It's nothing more than an alternative to .22lr. I shoot both the conversion kit and .223 sub for shits and giggles. Nothing more nothing less. I like to reload and I worked up a load "because".
 
Who gives a shit if its movie quiet?

If you shoot full speed ammo at living targets...they will never hear it. They will be dead or down before the sound gets there.

And I've shot tons of critters with subsonic .22lr....the sound of the round hitting the target is pretty loud at times. And ricochets are night and day noticeable.

There is no point shooting subsonic centerfire .223 when rimfire ammo is way cheaper.

And when shooting live animals your gonna want the energy on target the speed is supplying.

Sounds like you need a rimfire can on a solid rimfire platform.

Apparently you do.

It's a adjective phrase, a figure of speech. You know, like douche bag.

I'm not suggesting or condoning .223 subs over 22lr. I'm stating what I've used and observed while shooting both in 3 barrel lengths.

Both work with and have their benefits and weakness. Obviously 22lr is cheaper/easier to use.

I don't shoot enough of either, past plinking, to want to have a dedicated suppressed 22lr. The AR is fine for me.

Everybody has their shooting passions and favorite platforms. I've learned to accept that they are not always my passion or platform choices. It doesn't make them bad choices. But, to each their own.

Its hard to argue with "just because", I do a lot of things "just because" that my friends don't understand. The wife has learned to stop asking why, she just rolls her eyes now.

thanks for the input will give this a try. i ran a test at 20 yards with good results i'll do the shoot through method next week.

I do this because I read somewhere that the bullet can possibly exit the barrel with a wobble, but as it goes downrange may straighten up and fly right. After all, my biggest concern is how the bullet flies through my suppressor, which is attached to the muzzle--so I check stability at the muzzle more so than downrange.
I also built 2 alignment rods on a lathe. I bought some hardened round stock at ACE hardware that comes in like 36" lengths (One .250" and the other .375") and turned one end of them (about 4") down in a lathe until I could ALMOST get them in the bore of a 223 and a 308. Then I used emery cloth to polish them down to a perfect slide fit in the barrel. Left them long enough to extend all the way through my suppressor when installed. Overall about 15". They must be STRAIGHT. I can check any 223 or 308 for proper alignment before actually shooting through the suppressor by making sure the rod is centered in the exit hole of the suppressor.

For me, buying a suppressor was a pretty big "luxury" expense, and I do not want to risk baffle strikes in any way, shape or form.
