458 Socom subsonic bullet test
 

This is a 530 gr 458 bullet I've been playing with. I got 17" of penetration in wet news print. It expanded to .70 cal. Retained weight was 370 grs. Velocity was 1052.

impressive, who's bullet? distance from wet news print?

Great photo and just he results we want to see!

More details appreciated too.

They're from the same guy that's making my 300 Whisper bullets.
I shot them from about 10 yds from a 7" barreled AR15. I'm going
to do some more testing at 100 yds this weekend. They are also dual diameter so that you can load them quite long. I'll try to get more
pics up tonight.

You can get them from

Nice pics Alleycat, Big Thanks for the contact info :smile:

Ditto - I am looking forward to reading (and hopefully seeing) the results of the long range accuracy testing!

Good stuff - well done.

I shot this today at 90 yds. It may have been a fluke so don't look at this as what this gun/load combo averages. I simply have not shot it enough. 1076 fps, cartridge OAL = 2.263, 65 degrees

Teppo Jutsu 7" upper, 2x7 Leupold, and a registered SBR TI lower. This is the first (real)3 shot group I've put through the gun. I'm happy so far. I've always heard that SBR don't shoot as well, and I will be honest the gun is abrupt. I'll be shooting some more this weekend. I'll be happy with 1 1/2" groups. I have an Elite Iron suppressor on order so we will see.

That one appears to be shooting pretty well! Very nice AR.

I'd suggest the suppressor will help gun control. How much of a beast is it to shoot off the bags?

Look forward to the results of your weekend.

I was shooting the muzzleloader that day and had left the sabots on the bench on the first shot. I found most of them.:o The subsonic stuff is not too bad. Supersonic loads are a different mater. The recoil is manageable, but there is a big fireball and a lot of upward movement. It's a lot of fun to shoot and at 23 inches you can almost put it in your pocket.

Great advice - exactly what we want to hear. The silencer will make a difference to the handling I'm sure (but you can't wait for that to arrive and get fitted).

I think we are all interested in how the load testing goes on the weekend and feel free to be as honest as you like about what works and what doesn't - I know I'm learning a lot on this thread.

Keep up the good work.

Short barrels have accuracy.Its the recoil momemtum that moves the gun before the bullet exits that throws the accuracy off.If you locked it down and did benching it would show.

tp555 - very true. Bill Calfee demonstrated that in one of his 22lr trials when he cut a barrel down to one inch and shot some very tight groups.

I knew someone would call me on that statement without a qualifier.:smile:
Short-fat-stiff-heavy barrels have better harmonics. Short light guns sometimes suffer from portability issues. This one points quite well.

I shot one round into wet newsprint at 90 yds.

Beginning End
530gr 373.7gr
1.410 long 0.880 long
0.725 wide

Load was 22gr of VV N110 This is the same load that produced 1076 fps

7 inches is a little short for my personal liking but a can will make all the difference I'm sure. I'd be keen to have a 14 to 16 inch barrel in a bolt gun but that is a personal preference only and the fact that a 7 inch barrel is proving functional is fantastic.

As a result of this thread I have been looking at the range of 458 projectiles on offer and am impressed but what could be possible from the SOCOM case.

Keep up the good work!

It's too windy to shoot for groups today, but I did some low velocity testing.
http://i830.photobucket.com/albums/z...62Socom002.jpg
17 gr of VV N110 average velocity was 856.2 fps. Bullets penetrated 14inches, jackets separated at 12.5 inches. The lead core = 317 grs each. One jacket = 90 grs the other was 78 grs. If you plan on shooting at deer at 500 to 600 yds they will expand. 250 yds will be my personal limit even with drop compensation built into the scope.

Agree with the 250 yard range limit. What sort of "wound track" are these things making through the newsprint? Is it a big solid hole that keeps on going straight or are you seeing the projectile veering as it goes through the paper?

Great pictures btw.

They track straight. At 2 inches in you get the start of the wound channel. It continues to open up to a 3 inch hole at inch 12. At the 12 inch mark you find the petals that where shed. The channel looks exactly like a funnel. There is an abrupt stop to the wound channel and it goes back to a .70 cal hole for the remainder of its journey.

Pretty cool. Thanks for taking the time to share your findings.

Thank you indeed.

I'd really like to know how it quiets down with the Elite Iron can on it. I know Dale and Kathy, been to their shop, good people. Cans are a tad heavy but I hear they are quiet and very well made.

I have an SBR tac-inc receiver as well. You certainly have me thinking about this caliber now.

There are a couple bolt rifles that can be made to fire the 458 as well it seems.... Hmmmm...

Hi,
Talking about bolt actions rifle chambered for the 458 socom:
That would be great if winchester (FNH) could chamber their ultra small winchester 70 rifle in that calibre. The round would fit just fine.
Capacity might be limited to 2 rounds in the magazine though.
They could manufacture a metal bottom that would accept either ar-15 mags or mini 14 mags for greater capacity.

How about that?

ND

PS: meanwhile my first 458 socom rifle is gona be built on a standard winchester 70 action, as that was all that was available over here.

I'm ordering some brass as a first step. Then have to decide whether the 458 or the 50 is an option!

I got to do some shooting this weekend. Looks like 21.5 gr of VV N110 and the 530s will average 1.75" in my gun. 22gr shot better, but it's too close to the speed of sound. If I got any suppressor boost I would be cracking. I shot 4 groups with the 530s and 3 with some 480 Hawk bullets. Both bullets shot about the same as far as group size. I think the gun will do a little better with the suppressor. It weighs in at a little over 5 lbs and has 27.4 lbs of recoil energy. It started to get the better of me. It's very energetic to say the least. The .30 cal version is running at about 1.25 in my Whisper. The next thing to do is put some crosshairs on fur.

27ft-lbs is about the same recoil energy as a 300 Win Mag. My AI weighs three times as much and shooting strings without the brakes is exhausting.

Did you get a chrony reading for the 21.5 and 22 grain loading? My preference would be for the 22 grain with the can first of all but if that 1.5 inches is 100 yard groups then both loads are good enough for hunting.

Now we have to look forward to the results of fur time! Can't wait!

Alley cat what is your twist rate on the 458?

I have a .499 leitner wise I have been wanting to put my 510 can on and suppress but I think the twist is like 1/19 and will be too slow but I was hoping to get lucky.

Very nice write up and pics

Thanks Much

Jamie

1 in 14. 21.5 grs of VV N110 is running a little over 1050. 22 grs was in the 1080 range.

I've shot 6 deer this year with my Socom. All with the Outlaw 530s. 4 hit the ground instantly and 2 ran less than 40 yds. I included pics of 1 heart shot, one lung shot, and a exit wound. On the exit wound you can see the bullet fragment holes surrounding the main wound channel. The Socom is pretty devastating on deer no doubt about it.
