Ruger sp101 observations

I went to the range on friday with 3 guns, one of which was my good ol' sp101 3" .357 revolver. I've had this guy for about 2 years, and have put about 1000 rounds thru it in that time.

I have nothing bad to say about the gun. I do have some observations about appropriate cartridges to put in it.

I shot:

50 magtech 158gr JSP .357 magnums
50 magtech 158gr FMJ .38 specials
50 homeloads 158gr LSWC .357magnums, 4.5gr Titegroup
20 Federal Hydrashok 158gr JHP

The .38's were kittens. I also shot my Taurus 94 5" .22LR that day, and while there was a perceptible difference in recoil, I could still empty the gun (5 shots) in 2-3 seconds. All were COM, 10 or 9 ring on a sillhouette target at 25 feet. Single action shooting at bullseye targets produced sub-1" groups at 25 feet.

Next came the magtech .357's. They bucked quite a bit more, but follow up shots were still very easy to accomplish. If you can find some JHP's from magtech, they would make very good self defense rounds in the sp101. I could empty the gun accurately at 25 feet in about 3 seconds. All 10's and 9's on the same generic sillhouette target. SA shooting with this load also was very good. My bullseye target was getting a bit peppered at this point, but I think it was still sub-1".

After the magtechs, I shot my homeloads. These were an experiment to see if light, slow .357 loads would foul my barrel when using lead. The barrel remained very clean throughout shooting all 50 rounds. The titegroup powder smoked awfully fiercely, however. I really liked the recoil level of these loads. They were very economical to load (cheap lead and low powder levels), still much more powerful than .38's (definitely let you know that without being painful or slow to recover from), but didn't hurt in the tiny gun. If I can find a similar powder (Win231, Unique, etc) that smokes a little less, I will have the perfect load with that gun. These were great to shoot single-action, too. The sp101 is a very versatile gun, I wouldn't mind taking it out to harass rabbits some afternoon.

On a side note, the .357 titegroup loads smoked a lot, whereas my .44magnum loads I shot that day using titegroup did not smoke at all. Maybe it had something to do with barrel length? Anyways...

After being thoroughly pleased with the first batch of light magnum homeloads, I decided to shoot my SD ammo for comparison. Federal hydrashoks.

OUCH!!!:eek:

Not appropriate out of that gun. At all. I hadn't shot them out of it since I bought the gun. I must have not been able to tell what was an appropriate power level for SD at the time. They stomped much more than the magtech ammo. I would really worry about over penetration with those cartridges. Not going to buy any more unless I get a full sized .357 later on. I couldn't put all 5 on target in 5 seconds. It just hurt too much and required effort to make myself shoot again.

The verdict:

.38's are kittens out of this gun. The only worry is the typical magnum shooter's worry of building up lead that prohibits easy loading of .357 cartridges.

Light handloaded .357 cartridges are a dream come true. They hit your hand just right, are still controllable, and with proper bullet selection will do just fine for self defense.

Retail boxed magnum ammo aint too shabby. It'll do if you can't load your own and it still won't punish you.

The premium ammo I tried (hydrashoks) are loaded too hotly for this gun for my tastes. I will be developing a home-load JHP that smokes less for personal defense. In the meantime, I have a box of Fiocchi JHP's that will be loaded in it rather than the hydrashoks.

BTW, for those of you that think the sp-series cannot handle a full day at the range, there you have it: 170 rounds out of it. I also shot about 100 rounds out of my Taurus 94 5", and about 120 (50 .44special, ~70 magnum)rounds out of my redhawk .44. My hand is sore and I cut my thumb from all the hammer cocking, but it was a good time. It was also almost 400 rounds, 250 of which were magnums.
 
Yeah, those 125 grain magnums are a handfull in a snubgun.

I get quite a bit of smoke from W231 .38 spl loads, and unique has a rep for being a dirty/smokey powder (I dont use it myself, so no first hand experience). Bullseye isn't too bad. I've been told that the lube on cast lead bullets contibutes a fair bit to the smoke. For mag loads I've settled on blue dot, and jacketed bullets. Although I mostly use them in a 4" Colt, not my SP.
 
After much debate (mostly between the S&W 620 and 686) I actually decided on the SP101. I had rented a .357 3" and decided that would be the model to buy - but nobody here stocks it regularly. All that they have here in town are the 2" .357s. I just liked that size frame....
I thought the 3" would be a good all around gun (nightstand duty and target range) but now that I have to order one there are a few more options.
Since the posters on this thread seem to be fans and well versed in the SP I thought this would be a good place for some help.
Basically I only plan to shoot .38 out of the gun. I shot .38 and +p at the range and both seemed fine and actually quite similar. I figure that caliber is enough for what I need and while shooting a few .357s would probably be fun I can probably live without if it means something else is better.
  1. Am I right in thinking the 3" is better since the only carring I would do would be in the car on road trips?
  2. Would .38 be better than .357 since the ammo is better matched to the gun (cleaning and maybe accuracy - but I don't know).
I have read about .38s leaving rings but I was told .357s do the same. Would the .38s be closer to POA in a .38 than in a .357? Both caliber pistols seem to weigh the same.
 
I think 357s are a good match for this gun too, as long as they're not the fiercest loads. I've shot Remington and Federal 125-grain loads that are not pleasant at all. They have been relegated to my larger 357. I also shoot Magtech 158-grain loads, which are plenty powerful, but do not hurt my palm. One box of these is my limit, however, unless the SP is the only gun I'm shooting that day.

A really nice .357 load in this gun is the WWB 110-grain load. It's about midway between a .38 and the 125-grain loads, and I can shoot it at length. For defense, the Speer Short Barrel .357 shoots about the same, but with less flash. I think a practice/carry combo of these two loads is ideal.

I've shot a lot of .38s in this gun when I was just starting and never had a problem with rings. I also clean the gun after every trip to the range.

Rather than worry about lead rings or accuracty loss, I went with the SP101 in .38 Special. I figured I was only going to carry and shoot .38 Special anyway. Both versions handle and weigh virtually the same, the .38 version just has a little bit shorter cylinder. I just got it tonight, and had the opportunity to put 20 rounds of Cor-Bon 110gr +P through it. Even with that hyped up stuff, it was a breeze to handle. Recoil was noticeable, but not at all painful or hard to recover from. I need to get it cleaned up, but I *really* enjoy mine so far.

i would get the .357 and just use the .38. i'm not sure about the actual difference in the guns, but i think the new price is about the same, but the resale would be alot better on the .357.
 
You generally don't see a lot of smoke from powder buring. Most of what you saw most likely came from the lube on the lead bullets.
 
I was wondering if that was the case...

I loaded some jacketed .44magnums with the same powder and got no smoke at all.

Is that smoke basically airborn lead, or is it the burn-off of the lube?
 
I WISH I HAD A STAINLESS SECURITY SIX INSTEAD OOF MY SP-101!
My little SP-101 is less than 6 months old and I have 1,000 roounds through it.
I reload.
I replaced the main spring with a Wolf spring.
If I shoot with the trigger finger back past the knuckel, it shoot 3 inches off.
If I shoot with the trigger finger in the joint, The recoil causes the joint to hurt like hell.
Back in the 60's I had to have the pad sewn back on [A job related injury.]so I have no feeling in and do not use it.

If you aren't actually CARRYING the gun, then get the full sized GP100 revolver. The grip is a tad bit bigger and this helps controlability. It also holds 6 rounds rather than 5.

There are 3" GP100's out there, but for your purposes I would recommend a 4". While the sp101 will fit your proposed needs, it is more suited as a CCW weapon. You will be getting none of the benefits of the sp101 (small size, concealable, but still manageable recoil) but still inherit its drawbacks as a primary weapon (small grip, 5 shot cylinder rather than 6 or more, small sight radius, low visibility sights).

As far as .38 vs. .357, go with the most powerful that you can shoot quickly and accurately.

I suspect that "premium" .38+P SD loads are very close to lighter, bulk .357 loads in speed. If you are a hand loader, you can buy some nice hornady or sierra JHP's and load up some light .357 rounds and have a great defense gun.

If I had a 686 with a 4-6" barrel, I would shoot the above mentioned hydrashoks in it.

I run a similar theory out of my redhawk .44. Unless I am out intentionally looking for bears, I load a 240gr JHP to around 1100-1200 fps. This is a very light load for a redhawk and recoil is very manageable. It slaps the hand just right and leaves you ready to shoot again very quickly. If necessary, I can control this particular round with only one hand. When deliberately looking for bear, I carry 300gr hard-cast lead moving around 1300fps.

But I don't carry the .44 specials in it ever. I would much rather have weak magnums than potent specials. My specials only get loaded to let my girlfriend shoot the gun.:p

Same thing with the sp101. .38's usually only go in it for my girlfriend, except now I have a very low pressure, easy to manage .357 load for this gun. I'll probably just have her shoot those instead of buying more .38's.

Just remember: It's not all about how powerful the cartridge is... It's about the most powerful cartridge YOU can use to put 3 bullets in target in 2 seconds. For me, that's light magnums in my current guns. YMMV.
