Thinking about downloading my 223 to say between 22 magnum and 22 hornet power levels.
For goats in forestry areas that are normally shot under 70m.
Main purpose of downloading is to reduce noise level. Already have a DPT suppressor on it.
1:8 twist rate.
Anyone has any ideas?
Is this reasonable or is it better to stick with standard old 223 power level with a 55 grain projectile?
Put two extra baffles in the DPT and carry on
Have you had complaints? I wouldnt think it would be worth the hassle unless close to housing etc
No houses nearby, just for my own hearing.Quote:

Quick look and I see a hornet maxes a 55gr bullet at 2650 fps and a 223 min load for a 55gr bullet is 2800-3100fps depending upon powder.
Or 4 gr trail boss for 1050fps but i suspect they may pencil through.
Mild loads and upgrade the silencer.

Iv got 12 baffles on my 300blk Dpt
Just keep adding them till you get the desired result
12-13gr of AP100 and a 50-55gr projectile.
Greetings All,
Two of the ADI powders can be used in light loads. With 55 grain projectiles and AR2206H (H4895) you can go down to 16 grains (60% of 26 grains) and with Trail Boss down to 4 grains (70% of case capacity). You can find more info on this on the Hodgdon site. 4 grains of Trail Boss is likely subsonic. Accuracy is probably best a bit above minimum. You can't double charge the case with either of these powders. A very good thing.

This was slowed by ADI to match H4895 and given the suffix H for Hodgdon. Hodgdon found that AR2206H gave better results with reduced loads than IMR4895 and recommended only the former for that purpose. Most but not all of the ADI powders are offered by Hodgdon under their own names. I think Benchmark 1 is the only ADI rifle powder not offered by Hodgdon. All the data for the ADI powders is developed by Hodgdon. I can give you all Hodgdon names for the ADI powders if you like. Once again it is not an equivalent but exactly the same.
Regards Grandpamac.
2206h somewhere around 24.5 grns was my go to load for years.....its not hot with a 50 grn projectile and its noticably quieter than a hot load...drop it down some more and watch your accuracy....if you can go down to 16 grns I WOULD TRY 20 grns and see what you think....

There is an equivalent chart for most powders on the ADI website,lots are classed as same powder just different packaging
I would use a varmint projectile if you are trying to slow them down just to get some expansion.
Have posted this previously on thread "Reloading 223R to low velocity". May be of interest.
Not quite the velocity you're looking for but found the following with Trail Boss, CCI primers, 55gr V-Max. Howa 1500/ 16" barrel, Sonic 45 suppressor.
8.5gr TB :1678fps av vel. 204fps ES, 105fps SD. Accuracy so so.
8.0gr TB :1725fps av vel. 56fps ES, 28fps SD. Accurate load.
Using 8.0gr load on goats around sensitive areas successfully.
Have also tried H322/AR2219 15.6gr: 1738fps av vel. 67fps ES, 37fps SD. Works alright but decided to go with TB as had a reasonable amount on hand at the time.
Are you finding the vmax is expanding at those velocities?Quote:

Attachment 142042
Edit: I think IMR 8208 XBR / Bench Mark 8208 is another example.
They seem to be mostly,although i did get a couple that pencilled through yesterday.But I can live with the odd one doing that, out of 14 goats and two small pigs only two minimal expansion isn't bad. I will try some other projectiles shortly,only got about 20 of the vmax loads left Some people don't reckon they work but get the odd unexplained failure with a lot of projectiles.
Hope you can make scense of this, just copied from manual.

I'm mainly only using this load for shooting around sensitive areas eg. bordering residential areas and near camping ground. Still put in a work order with police for residential areas, avoids having a meeting with AOS.
I played around with 75gr Amax? a while ago for long range load with so-so results,single loading was a pain in the arse. Havn't persevered with this route. Went back to 62gr SP Barnaul which went good in my Ar and go alright in Howa 1500 but Hornady 55gr SP and 55gr Vmax do the job alright out to around 400 yards if I keep my shit together.Quote:

Try and get some trial packs from somewhere like Gunworks and have a play, only way to find out if they work. the "experts' aren't always right and rules are made to be tested/broken.Quote:

Speer 55gr Varmint SP 1769fps av vel. 30fps ES, 15fps SD 5mm group
Sierra Blitz Varmint 1756fps av vel, 58fps ES 30fps SD 4mm group
All these loads were shot using daybag as rest, on ground beside ute. Loads in first post shot at 100 yds.
Yesterday, shot one goat each projectile. All at about 25-30 yds. All expanded well, all high neck shots, substantial wounds. Need to test some more to check reliability but promising. Most importantly, residents approx. 40-50 yards away never heard any shots.
In comparison, 55gr Honady SP @ 2911fps at similar range totally destroys neck,left hanging on by skin.
