Just got a suppressor! Tried it on my 300blk AR with subsonic ammo, but find the noise of the action with my ear right next to it to be loud. I want to switch to a bolt gun, but don't want to buy one just for that. I do have a bolt gun in 6.5Creedmore. Are there any 6.5CM subsonic recipes?
1) simple enough for any cartridge with trail boss, first find the maximum amount of trail boss your case will hold by volume.
2) your starting load is 70% of that amount of powder
3) if your starting load is too fast work your way down slowly while chronographing your loads.
4) remember to check for bullet stability before putting on your suppressor (shoot cardboard look for clean round holes upclose and farther away)

Thanks! looks like just what I needOriginally Posted by Artful
The other thought is to change your gas system to adjustable.
A gas tube on your AR making it a straight pull rifle.

or change the gas block to adjustable

didnt know about adjustable gas tubes, thanks Either way, I am looking to use a bolt gun for the silencer, but thanks for the info
you could send it to me and i'll test it out on my 300 bolt gun, it's got the standard x24 threading
I got some ammo loaded too.
results in 30 minutes or less....
I doubt the info will transfer over to your AR but you'll know how well the can works.
That's the thing about the gas system on the AR
- turn off the gas no action noise and no gas coming back out of the chamber.
You made the AR into a straight pull bolt rifle, but with a quick adjustment of the gas system it's back as a repeater.

dang it Art..
True, but given that my 300blk AR is my home defense gun, I don't want to give myself one more thing to screw up like forgetting to switch the gas back onI don't experiment or play around with that gun
Subsonic 6.5 Creedmore?
The correct spelling is Creedmoor!

What is a 6.5 creedmore if I may ask?
Did google break?
http://en.wikipedia.org/wiki/6.5mm_Creedmoor
The 6.5mm Creedmoor is a centerfire rifle cartridge introduced by Hornady in 2007.[2] When loaded with heavier bullets, cartridges such as the 6.5x55mm and 6.5-284 are capable of greater muzzle velocity due to their longer cases and larger powder capacity. However, due to its shorter overall length, the 6.5mm Creedmoor is more flexible in its ability to be chambered in short-action bolt rifles and AR-10 rifles.
6.5 mm (.264") bullets, in general, are known for their relatively high ballistic coefficients, and have seen success in rifle competition. The 6.5mm Creedmoor is capable of duplicating the trajectory of the .300 Winchester Magnum while generating significantly lower recoil. Also, converting a rifle chambered for the .308 Winchester (or any of its offspring, such as the .243 Winchester, 7mm-08 Remington or .338 Federal) to 6.5mm Creedmoor generally requires little more than a simple barrel change.

Noted - Thank your for your correction - but we understood what we were talking about.

If you don't want to cut the gas off in your AR you could load the 300blk ammo with powders that prevent action cycling and maintaining subsonic velocities. I have a green dot load that won't cycle the action, is really quiet and still has about 1000fps. Shouldn't be hard to tinker around and come up with a couple of loads that would work for you. I do agree, that the AR action noise is loud. Even my 22LR upper suppressed is loud to my ear when shooting. To someone that is a bystander it is giggles quiet.
Yes, I stood behind someone shooting my AR and was amazed how quite it was since shooting it with the action next to your ear is so loud!
Its just as easy for me to develop a load in a chambering for a bolt gun that I own. I am going to try 6.5 Creedmore with the Trail Boss powder.
So why is this cartridge all the rage while the 260Rem seems to languish? I see so many bolt action rifles for this on GB for sale but very few in 260 Rem.
My load data books are too old to include this cartridge so cant compare ballistics. Are the ballistics of this better than the 260 Rem? Cases for this can be made by shortening the 260 Rem case correct?

You use the words "this" instead of the name of the cartridge. What round are you questioning for comparing to your 260 Rem? 300blk? 6.5 CM?
If its the 6.5CM, I went with CM instead of the 260Rem because I can get high quality factory ammo from Hornady. Other than that, they are pretty similar.
I was referring to the 6.5 creedmoor the cartridge this thread is about.
