Thread: Subsonic project

[QUOTE=Bill999;1211780]30cal subs are considerably more quiet than 44cal subs but the 44 is quite a bit more quiet than 450bm so I quite like the 44 as a good compromise that still puts big holes in things

I’m looking forward to what the 8.6 creed/blackout with fast twists turn out but as a set and forget 44 is better again If we can get a lead hollow point like an overgrown version of the 155 30cal lead cast as they are deadly and make things super economical

You mean this

do the 260gr shoot OK at subsonic speeds? rossi 44 mag loaded to 1000fps? Will they expand?

Yes they expand; they are very soft from feedback from people that use them they don't exit pigs where the 280 FP does

@shooternz
What I would really love is a scaled up version of the Winchester 22 HP Subsonic bullet. If that bullet weighed 350 gr and was made of the same lead mix as the Ausi Winny it would be the ultimate. I used Greenhills formula to check against the estimated length and it works

Lyman still make the 330 grain HP Gould mold but it is a pain the arse it is only a single cavity, to hard to do a pile of bullets one at in time
hard a 54 cal HB Minnie mold never again, If I had a 45/70 maybe for personal use only.There is one HP I have seen about 385 grains depending on lead
composition

They look perfect Rob, can't wait for mine to turn up.

STOP IT...... them are nearly enough to arouse a fella.......when are you going to do same in .45cal???

The only outfit that makes the 45 HP mold I want has gone missing may have go for a heavier HP than I wanted,
I think a 30/30 will come first getting more requests for that than the .45 sorry children

ok Dad....will keep drilling them with 7mm drill for now.......they sure do the bizo on small stuff,sooner or later a deer will make a slip and will get to see how good on them too LOL.

Bit of an update found a DPT 44cal suppressor with 14x1 thread pitch. @Friwi the barrel diameter at the planned cutting point is 21mm, will that pitch work? they also have a 45cal suppressor 1/2x20.

Powder wise all I could find was APS350, APS450, AP100, Clays and Lil gun for full noise loads. Any of these stand out?

Hi mawser, the 14x1 will work. Check the diameter of your barrel 120mm back from cutting point to see if the rear end will fit ( assuming the suppressor your getting is an overbarrel model).

How is Hi Scor 700 shotgun powder for subsonics? Accurate?

I have some but have not got around to using it. There are published loads for it for 44mag, 45Colt, 44-40, and 9mm. Research tells me that 700x is the same powder whether Dupont, IMR or Hogdon branded. It does have a varied production history so if you have old powder try and use published data from an old manual of the same era. There are plenty of old manuals free online at various sites

Going to try that in the .44 mag when out of lockdown, I use it in .38 .357mag and .45 ACP pistols
it is in the Red Dot Bullseye AS30 class powders so should be good velocity wise
Look up loads for the .44 Special with it; the max load will be a good place to start in the mag case
a 245-250 in the .44 special velocity is 700 to 800 in a pistol, We are talking Cast bullets here the don't build pressure
like jacketed.

Ive tried 700X in a few guns. Functioned well, although im only looking for minute-of-steel-plate.
9.6gr with a 200gr plated cycled the desert eagle, shot real mild, and most importantly kept velocity under 1250fps with the plated projectile.
8.4gr with a 240gr cast is a start load, was apparently only clocking 700fps out of a SAA replica. Max load is 9.5@1.620" for 1185fps according to Lee.

https://www.hodgdonreloading.com/reloading-data-center has 5 loads listed for 700X in 44mag.
