I was wondering if anyone has played around with a suppressor on a 6x45. I have not seen any load data for subsonic rounds nor do i think this caliber is designed to be subsonic and function properly. I have a 6x45bbl on order but i was thinking about a suppressor but i don't really know what I want to do. For subsonic stuff i was thinking 300 blackout but from what I have found the 7.62x40wt is easier to form brass for but I haven't seen any subsonic date for the wt load either. I am looking for other people's thoughts and experiences

I am looking for other people's thoughts and experiences I have never seen it either. No rounds that are out other than the Whisper come to mind that were designed for suppression. Nothing says you can't use some 223 data for load levels. It should be easy to make a very quiet round. My personal thoughts are that if it will be used in hunting bigger bullets are better. Greg

Do you know what can be done to keep the gun functioning properly? I have never experimented with getting the gun to function with low power loads

I have never experimented with getting the gun to function with low power loads One method is the use of an adjustable gas block to give you more gas when you are sub-sonic. Dwell time on the port comes into play as a shorter barrel with a longer gas system tends to not allow you the luxury of the extra gas. I don't shoot suppressed rifles but there is no mystery. I'm sure that if you peruse some of the more tactical Forums you will get plenty of advice. The guys over on AR15ARMORY.com that I am heavily involved in could give you plenty of pointers. Greg

Thank you Greg, I will check that out.

I never had a use for a suppressor in the past but now that you can use them in Arizona for hunting I may well get one. I shoot in F-Class matches with a guy that shoots a 223 that is suppressed at 50 yards. He kicks my butt, he is a High Master, but that gun sure shoots.
I might cheat and put one on a Savage actioned BHW bolt gun barrel so I can really rack 'em up for PD's here.
BTW, if you do one please keep the board up to speed. I will be VERY interested in your choice of can manufacturer and why you chose that one.

I am looking for other people's thoughts and experiences While I'm still waiting for the approved Form, me and several other compatriots are readying uppers for strict suppressed testing. 6x45 has been added to the list, however our test barrel is an 16" barrel for this caliber. I suspect it will act like the 556 and 68 in efficiency both sub and super.

One thing I did overlook was the TWIST rate of the barrel. You may have issues shooting the slow one if you can't get down around 1:8 twist. Purely a theoretic thought from me.
I would contact the guys at Gemtech or some other suppressor outfit and see what they say. A BHW might not be fast enough for the task.

I didn't even think about twist rate. The barrel that I ordered is a 1:9. The suppressor I have been looking at is the Huntertown Arms, they have a sleeve inside in case of a baffle strike that protects the nfa part of the suppressor. all of the parts inside are replaceable so you aren't out the money for the stamp if something happens. Plus, they are made here in Indiana and one of the guys from there brought one by and I got to test it out on an AR with a 22 conversion in, in semi auto, and in full auto as well. I have been thinking about going feral hog hunting down south and I think it would be great for that.

I actually emailed them today to ask them some of my suppressor questions so hopefully I will have some more things to add later

Ive never heard of a 6x45 shooting subs, but seeing as how there is a 6mm whisper, it should be possible. Not as efficient, but could work as long as you are using a carbine length system with a can, or maybe a pistol length barrel w/ pistol gas system. But then there's another stamp if you wanna sbr. N about the 7.62x40, i shot subs outta the one i had. Just gotta use heavy bullets w/ shorter ogives than wut the 300blk can use. Also would need 2 request an 8 twist instead of the standard 12. They didnt stabilize at all in mine. Just my .02. Please keep us posted on the 6x45. Sounds like a fun project.

I ordered my barrel with a 5/8 x 24 threaded muzzel. I have been shooting 22 cal thru a 30 cal can fore some time with good results. I found some sub loads on the net for 223 and 30-06 and developed some myself. When I get my barrel I will start with super sonic then play with some subs.

You don't have to be shooting subsonic ammo to get great benefit from a suppressor. It won't be silent like the movies but it still makes a HUGE difference in sound signature, not to mention complete flash suppression and tremendous recoil reduction. Consider that a .308 suppressed shooting full-house loads sounds like a .22LR.
As far as the 6mm Whisper goes, it uses a short case and a very long, heavy for caliber bullet. The full length case of the 6x45 is going to limit your bullet selection in the AR. If you've messed with the .300 Whisper or the .300 Blackout in a 16" barrel you'll know that it can be quite finicky WRT function because of the small powder charge and the large barrel and gas system volume in comparison. Many have found that a pistol length gas system is the most reliable setup, regardless of barrel length, to maximize port pressure and dwell. The light bullet of the 6mm's (compared to a .30cal) is going to make it even more fickle. You'll struggle to keep it subsonic in the first place and the tiny powder charge that is going to dictate is going to make AR function a near impossibility.
If you're not limited by weapon function or magazine length, you could work a subsonic load for the 6x45 fairly easily. Trail Boss has become the go-to powder that pretty much every rifle cartridge for building sub loads.
If you're working with an AR, just forget about the subsonic aspect and enjoy the benefits that a suppressor provides. I'm of the opinion that every cartridge benefits from the use of a suppressor and I won't be dissuaded from using a can just because subsonic loads are not possible/practical with a certain rifle or cartridge.
