9mm 147 grain subsonic project?
« on: June 22, 2015, 06:18:40 AM »
9mm 147 grain jhp subsonic ammunition used to be very popular for defensive use.
Is anybody interested in a project to simulate this?
I suppose if we could run supressors this would be more interesting.
The reason that I ask is because I recently stumbled upon some military 147 gr. Subsonic jhp ammo and I thought it was mildly interesting.
What, Me Worry?

Next to 124gr most of my 9mm semi-autos do very well with 147gr projectiles as far as accuracy is concerned. Before this latest release of self defense ammo came out over the last 2 or 3 years using lighter faster projectiles I preferred 147gr JHP. So I would be interested in any data you might share.

Thanks!

Ya know 20 something years ago hpd was using winchester q4217 so I simulated that load.
Today, I can't find that bullet or the powder that I used.
So this would be a whole new round of tests using whatever is available today.
If more fellas are interested, I'll do it.

im interested with this data as well. i bought a speer gold dot 124 gr and 147 for defense

ops sorry, you were referring to sub sonic load. nvm but still interested

I've been reloading 124gr hbfp subsonic for a 9mm 1911 that shoots pretty accurate and are reliable.  The benefit I see is it's accurate and you can get follow up shots pretty quick compared to normal 9mm loads >1200fps. 

Interested to see what you find!  You planning on shooting ballistic gel?

Thanks OF,

The Gold Dot Project was very thorough and full of good information. I look forward to seeing this project get started. Assuming enough people are interested.

are 147 gr gold dots sub- or super-sonic?

The Gold Dot project involved 124gr GD's moving at ~1150 feet per second which are supersonic. But 147gr are usually subsonic.

oh,ok
i guess i'm interested in this too
since i just bought 6 boxes of gold dot 147s

i'll donate the control subject GD 147s

im just wondering, what is the recipe on building a subsonic load? is it heavier bullet for instance 9mm(147 or 165) quickiest powder? on what velocity? The reason i ask is, i went to freedom munition website ( xtreme bullet sister company) and they sell Hush subsonic load. their bullet of choice are 147 and 165 gr. and its posted they are using the cleaniest  and quickest powder.

I've been using berrys 124gr hbfp and had luck with ramshot silhouette and ramshot true blue.  Looking at the burn chart at the link below, they're not the fastest powders.

(Please let me know I'd anyone has a pdf scan of a hard copy, published list of burn rates that they're willing to share)

I tried ramshot competition (faster than true blue and silhouette), but that was only accurate in loads that didn't reliably cycle for me.  I considered playing with the 147gr fp, but I quickly became a fan of the hollow base offered with the 124 gr hbfp  bullet.  It had the similar bearing area against the barrel as a 147gr fp and has more data published for the powders I have.

im not 100% sure if the chart from reloadersnest.com is accurate. i found this chart from hodgdon website.

I haven't messed with GD 147's but I do have a little load data on 147 XTP's that I worked up with HP38 that was subsonic out of a 4" M&P and a 5" RIA 1911.

I have purchased Winchester Defend JHP 147 grain for my 9mm SD round.  The performance in these in reviews seem to be stellar.  The recoil is very mild.   I've read 147 GD's are not too good out of short barrels.

i tried the 147 GD. for me its a little jumpy on my g34 compare to 124 gr but less noise. i guess next load is to make some 147 gr with the lower load data as my 124 gr. i read some load data from silencer talk and some used 147 gr using 3.5 gr of BE

I'm right around 3.2gr BE with coated 147's.  Still haven't chrono'd them though.

what kind of velocity are we looking for best result even without a can?

Work up your loads and experiment with your gun.  My 9mm 1911 with 5" barrel likes around 980fps for accuracy.

i did some researched and they said in order to achieve sub sonic load is to be below the speed of sound which is 1,100 fps. so your load is good tailored to your gun.
