Default 222 subsonic load anyone

Hello fellas

I would like to know if anyone has a subsonic load for a 222 using 40gr bullets?
Or point me in the right direction. Thanks to all for your help.
I have both blue dot and 800X powders but have not been able to come up with any Trail Boss.

All my subsonic loads are now made with Trail boss as it is just so much safer than fast burning pistol or shotgun powder. No chance of a double charge.

Here is some info for 800X and Blue Dot from Calhoon for the 223. I would start with the min load and work up carefully. Near the bottom of the article he talks about loads for the 222.

+1 on what Kevin just said. Especially if you have any 22lr rifles with a match chamber. Even some of the semiautos that are not match chambers are pretty accurate if you test and find a particular brand HV ammo they like.

A couple of years ago I was playing with a 10 inch Contender barrel in 222 Rem. I was shooting 55 grain cast bullets subsonic thru a suppressor with Tite Group.
I don't remember the exact load I was using but start with 3.2 grains and work your way down until you achieve subsonic velocities. Make sure the bullet exits the barrel with each shot.
I stopped using the 222 Rem because I purchased a 1/7 twist 22 Hornet barrel to shot heavier 75-80 grain bullets.
Trail Boss was recommended to me for the Hornet but is it still available?

Trail Boss is on the list of stuff I have not seen for sale for a long time. I am glad that I have a jug.

Looking at the Lyman cast bullet handbook they are showing 5.0 gr. of 700X pushing a 41 gr. 225348 at 1872 fps at 25k CUP and 6.6 gr. delivering 2187 fps at 40k CUP. So a charge weight in the 3.0 to 3.5 grain range ought to get the velocity that you are looking for. I'm a believer that powder charges for reduced loads should be such that a double charge can't fit in the case or pressure safe should a double charge occur. I've used a case full of Trail Boss and a cast bullet in my 22 Hornet for fun, but if I recall it was still above 1100 fps.

Going this route I would think that a plain base 22 caliber cast bullet would be optimum, as placing gas checks on these bullets is a chore and they aren't needed for the application. A mold similar to this:
would be what I would be looking for.

However, unless you really want the fiddle factor, the price of 100 rounds of 22RF ammo is about the same price as 100 SR/SP. Personally, as much as I find satisfaction casting and shooting my own bullets, I'd be looking at the 22 RF option as the best path forward.

Just in case you are wondering a 222 case holds about 8 gr. of Trail Boss to the top of the neck.
