Ruger LC Carbine 5.7x28mm

Honestly if I don't find a PCC I like soon I'll probably make a 357sig Mac11 bullpup.

This is my only bullpup:

"However, I just realized that was only because of parallax from shooting at 10 yards. Will readjust it next time I am at the range."
Not to sound nit-picky BUT open sights don't suffer from parallax issues(nor do most 'dot optics', for that matter).

The Parallax wheel on my 10-40 ffp gives me accurate ranges to over 700yds.

One of mine

Last week's ice storm delayed lots of things, so I just picked it up yesterday.

First impressions: Lighter than most carbines in this style, fore-end is slim, but a bit square. Sights aren't bad for budget back-up sights. Trigger is better than most you got out of the box in the 90s. :D I think it will be fine for shooting under stress (speed), but it could use a little bit of improvement for range-day accuracy testing...

Speaking of that, I put a little Leupold VX-Hog 1x-4x scope on top for testing, but it will most likely wear a red-dot optic down the stretch. It also got a mini-comp from HB Industries which is o-ring retained so easy to remove for silencer use. And I put a Crimson Trace laser on it as well, with thoughts of it becoming the wife's new "Get out of my House!" gun.

Hope to have the chance to range-test it next week.

I just got another!!!

Hello guys. New to the forum but like most of you I have been shooting and reloading for over 45 years.
I purchased the Ruger 5.7 carbine over the winter because I wanted to find a good throw around varmint rifle, kind of like the Ruger 10-22 but different just in case I seen something in the fields on the way to work.

I have looked all over for load data for the 5.7 and 90% of it was for pistol and the other 10% was for the FN PS90 and this information from what I tried was unsafe to say the least so here I am loading "SPECIFICALLY" for the Ruger 5.7 carbine.
I wanted to share some data for the ones that have been looking like I have and found nothing for the Ruger 5.7 carbine.

Well the snow is finally gone in Minnesota and I had a chance to get out and do some testing today.
So this is for you guys that might be interested in reloading the 5.7 if you don't already have any load data to try. Also. If anyone else has any data to share with me please post thanks.
Of course, use this info at your own risk as I take no responsibility in your loading good or bad habits and this also goes for me and other if you guys have any data to share.

Now that we got that out of the way.

Using my labradar this is what I had found.
I won't post the lows and definitely not the high loads as I want this to be safe and believe me the loads I found for the FN P90 are not for the Ruger.
I found that HS-6 works very well and burns clean with this load data.
So here we go.
Once fired brass.
Trim case to 1.130
Winchester #41 primers
Hornady 40gr Vmax
All loads Hod HS-6
OAL 1.580 no crimp

Temp today at time of testing
70 degrees and 30% humidity
elevation is 890' a.s.l
6.0 gr - 2345 FPS
6.1gr. No testing as of yet
6.2 gr- 2414 FPS
6.3 gr. No testing as of yet
6.4 gr 2464 FPS but I had one blown primer in this group of 5. There was no pressure signs on the other primers so I am sure this might have been a case that was already hot from the factory or a bad pocket.
Note: I am using "supposedly" once fired brass that I had purchased from the range.

I'm working up more loads now to test accraracy, not that there is a lot of load choices with 5.7 because .1 gr makes a big difference in this little case as I'm sure you all know.
I can tell you that the factory ammo that I had shot through this carbine showed
2030 FPS on the labradar. So as you can see there is a big increase from using pistol loads vs loading for a carbine.

I will be testing for accuracy now that I have my pressure testing finished.
I will be testing
6.0
6.1
6.2
6.3
6.4
For safety reasons nothing over 6.4 will be discussed as some have taken this load to 7 and over.
I hope some of you find this helpful.
Once I get a repeat of today's temperature I will be back on the bench and get more info and I will post this for those of you who are interested.

There are plenty of 30 carbines around, you just have to pay collector prices for them or buy one of the less than stelar clones. I suspect the bad clones might have had something to do with the 30s fade into the background. The 30 carbine has always been one of my favorite rifles to shoot, but alas, mine has past on to a son, it's third generation owner.

A couple of observations since getting a 57 Carbine. I think this is going to be one great home defense gun. Install a light, and a "shake awake" optic, and you have a pretty potent package. The ability for even a relatively new shooter to put multiple rounds on target in quick session, makes for a formidable package. The round also becomes less penetrative than a 9 mm bullet when it hits a sheet rock wall. So there is less chance a stray round will strike a loved one in another room. And lets face it, if an intruder is hammered by several rounds of 5.7x28, he will be less likely to continue to be a threat to you or your family. The U.S. Secret Service has used the 5.7x28 for many years in their FN P90 submachineguns, and have been very impressed with it. And as with ALL handgun calibers, it is still bullet placement that wins a gunfight.

There are very few standard factory magazines that hold more than the 20 rounds of the Ruger 57. And there are already aftermarket manufacturers who are making magazine extensions for the 57. I'm sure as this system takes off, there may even be a Ruger factory magazine with higher capacity coming. Even with "just" 20 rounds, I don't think a home owner is not going to have sufficient ammo to stop a home invasion.

The down side of this little carbine is of course the cost of the ammunition, it is higher than even most 5.56 ammo. I feel with all the new weapons chambered for the 5.7x28 cartridge coming out from Palmetto State Armory, CMMG, AR57, and this Ruger 57, the ammunition will have a much stronger market. The ammo companies can see the potential to stepping up the 5.7 production line.

So is the Ruger 57 perfect? No, but IMHO, with the addition of a light and optic, it is an awesome choice for a home defense weapon.

just purchased my 5.7 carbine fired 20 rounds and the firing pin broke off in a primer sent it back to ruger hopefully will be back soon!!!

Ouch... they are usually quick, but wow.
