I am interested in a low noise 223 load. something that makes maybe a little less noise than a 22 mag

From what I have read, you need to keep the round subsonic. At sea level that is roughly 1116.4 fps, but this number will change dependent upon temperature and atmospheric conditions, based on altitude.

Do a search on the Whisper family of cartridges that may help.

Try 35 to 45 gr. bullets and 5 to 6 grs. of Blue Dot. Seafire did a write up on this awhile back including measured velocities, and comments on energy and noise level. Per his test results this is what you're asking for.

Please use care to avoid double or triple loading at the levels in question. roger

is there any loads I could do with standard poweders?? I really don't even wanna have pistol powders on my bench

What if I used the cast bullet data in my book?? I have a load that is 10.7grns of imr4198 for 1756fps, with this work with a 55 blitzking??

Try it. The only potential problem might be a poor neck seal allowing a little gas to escape. If you're wearing safety glasses you should be ok.

Loads for cast bullets can be questionable with jacketed bullets. In the 9x41 a 300 gr.gas checked bullet can be safely pushed with a compressed load of 34gr. 4198. If that were tried with a 300gr. jacketed bullet the minimum problem would be hammering open the bolt or worse. Garuuunteeed. roger

also what would happen if I used a slow powder say like RL 22 and only filled the case a little more than half full, so as to prevent an accidental double charge?? would this produce a safe reduced load??

Most probably safe,yes. As you get into reduceing loads to the level you are talking about and using slower burning powders you are reducing peek pressure and again get into the sooty marginally sealing area.With the slowest burning powders there could be a hazardous potential such as secondary ignition.Never saw this happen myself but a lot has been written about it. roger

I picked up a silencer from High Tech Gunworks in Boise Idaho from George Vais, the originator of the Vais muzzle brake. Mine is a universal one that will work on a 22 lr rifle, 22 lr pistol , and a .223. George had this product written up in Special Weapons magazine 2005 with a test results that showed that a Vais muzzle brake on a M4 Carbine in a .223 silenced was a little bit quieter than a Ruger 77/22 subsonic road. His phone number is 208-323-7674. I love mine and love the laughs it gets on a 22 lr rifle when people hear the little noise that it makes and it seems to increase the velocity a little bit.
