Reduced loads with fast powders ie;trailboss

[Gwion]

Personally. I'd find a mate who could use the powder for the intended purpose and buy more powder suited to my own purposes...

Hi gwion, unfortunately all the blokes i know are bludy stooges mate...they would all want it for nothing...!!!

If i could get decent payed work in the bush & live on a farm id buy 2 clay throwers & zoom through the powder...!!!

Ill use it eventually i guess...

ADI never returned my email either...

[Gwion]

Nothin' like having tight arse mates....

[Stix]

Got a response from ADI...
Im taking it as a flat out cant be done...

They have also sent me a pdf with bulk density & volumetric mean density rates of all powders...
So for those interested, pm me yr email & ill send it on....

Expect at least two weeks to get a reply. Two or three experts will look at it first. They are very heavy into procedures and very conservative, due to what they make.

You talkin about a response from ADI or the stooges i know at the range making a decision on buying my powder...?

[Oldbloke]

ADI. Usually pretty slow. But given your PM I must be wrong.

Im a trailboss user & am very confident with it.

But i also have 4kg of ASI AS50N laying around for the shotties that doesnt get used much these days...

Im wondering if anyone has any experience with loading centrefire cartridges with this powder (AS50N), for reduced loads...?
And if so, is following standard protocol (say starting loads with 70% case volume & work up) a relatively safe thing to do...?

I havnt looked into it yet, so not sure of bulk density etc, but naturally thought id start with the countries best brains trust...
Curious to hear peoples experiences if any...

Cheers

If you are chasing a subsonic load, 8gns behind a cast bullet of 160gn will work fine. I have loaded 1000s of cast bullet subs in 303,8mm, 6.5mmx55, 7.62 Nagant, 3006, all with this rule of thumb......Any fast burning pistol, shotgun or rifle powder upto and including AR2205. NO SLOWER in burn rate for Subsonics. Before any one gets on the Trailboss train.....yes I do have a 4kg tin which I'm yet to try, I'm not convinced it's the be all, and end all, that's all.

Never used fillers either, no need for them.

I don't have anything for the .204. I have no experience with loading for .22-250. I have very little experience with reloading. So I've just simply typed in some data from the Lyman Cast Bullet Handbook 4th Edition for 22-250 Remington:

I think I should just tweak the ADI Powder equivalents disclaimer a little to suit the above tables:

Note: These tables are only approximate. Actual burning rates can vary depending on the calibre, weapon, loading components and practices, as well as from powder lot to powder lot. As a consequence it must be understood that I cannot accept any responsibility for the use of this information in any way.

[Oldbloke]

They are approximate only.

DISCLAIMER; do not try this at home. At the risk of unmasking my recklessness; If you’re not super precious about the gun, personally I reckon I’d have the kahunas to pull the trigger on 7.0grs in a 204, say under a moderate jacketed pill. Use thick brass and tilt the barrel skyward to get the powder back on the primer, and shoot the first with your face away from the action. DISCLAIMER; do not try this at home.

Yep 2205 and all above it work fine for subsonic cast bullet shooting. Great fun in the 50m service rifle match the local pistol club shoot. Pretty accurate!
