First outing with the GP100 SS

[Ekalb2000]

Had some 125grs loaded up. Some with Unique (7gr) some with 2400 (14gr).
Lubed with Lee Alox, I am really begining to hate this lube. It leaded so bad. Was very inaccurate. I as not trying to get full magnum loads with this boolit.
It might also be that the boolit is just going to fast.
I cleaned the brl.
Fired some Lee 358-158 flat nose boolits with 12gr 2400 with home made lube (50/50 beeswax/vasoline), man what a difference. Apples and oranges.
No leading, slight lead flakes near muzzle. Excelent accuracy, 1/2in @25yds.
Set up a soda can at 100yds nailed it, left a hole on the back side almost 2in wide. I was very impressed with what that boolt did.
All in all put about 250 rounds down it today. The cylinder is black. Kind of want to leave it that way.

Also had the single six out. Fun little gun.

Pick up my rossi 92 monday. I hope this boolit feeds and shoots well in the rifle.

Glad to hear the GP100 is fallin in line for ya !!

I never got alox to work either.

I shot my first 1 hole group testin Lymans IDEAL 357446 boolit & 15.6 grs. of H-110.

& yes I fired it more than once !!! It was 20 rounds thru a 1 1/4 inch hole@25yds.

[leadman]

That Lee 158gr FN should feed in your lever. Works great in my Marlin.

[Ekalb2000]

As much as I keep hearing about 110 for the 357 and 44. I might just have to pick up a pound for full loads.
GP, did you have any leading issues with that boolit? That is a non-gc design?
What velocities were you getting?

thanks

With the Lyman 358429 over 16.3 of H110/W296 I have had excellent accuracy with both
Smith & Wesson 586 and Ruger Security Six. This is listed at 1500 in the book, but that is
a longer barrel than my 6" tubes.

I don't think liquid Alox is good much beyond 8-900 fps in most cases. Some have had
success, many have not.

I have found that I need to double lube with LLA on my Lee TL 200 gr SWC for my 45ACP. If I do not double lube them I get pronounced leading and this is at around 850fps.

[dale2242]

H110/296 is the most accurate powders for heavy loads in the 357 and 44 magnums I have found. While chronographing, I find they have the least ES. With these powders, I always use magnum primers and a heavy crimp.....dale

[Ekalb2000]

I thought you could only go up to around 1300fps without a GC?

[dubber123]

I have seen over 1,400 with plain base in .44 mag. Alloy, lube, powder selection will get you there. Gun dimensions have to be correct. Throats/boolits smaller than the bore will get you leading regardless.

Ekalb

with that boolit & my alloy I stopped at 15.6 which is close max for the 358156

The 357446 looks like the 358156 but has 1 crimp groove & 2 lube grooveshttp://i746.photobucket.com/albums/xx110/GP100man/102_0195.jpg

Out of my 6" Iwas gettin 1290 fps , which will do anything I need to do .

[Ekalb2000]

Darn tootin' that will do anything you need it to.
Sure do appreciate the info.
Next time I am at the gun store I will pick some up.
Funny thig about your load, Hodgdon's site says its much faster than that??

[Angus]

Hodgdon's velocities are with 10" test barrels... It makes for some very impressive velocities.

That's one of the few things I dislike about the Hodgdon manual. You end up with no idea what a realisitic velocity will be.

That boolit is out of an obsolete mold ,I just found a 2cavity & recieved it today !!!

On oldguns.com is a 4 banger , I just don`t think my wore out hands could handle it though.


Yeah , the ole velocity trick to get ya to buy hodgdon powder !!!!

Heck they `bout own all the names anyways !!!!

[44man]

Hey GP100, your boolit needs a shave! :bigsmyl2:
If you have boolit fit you can shoot a PB very fast by just tweaking hardness. I have had them up to 1800 fps and regularly shoot them over 1630 fps. I don't know how much faster you can go because I don't have a gun to try them in that shoots faster. Moving away from gas checks because of cost has shown me there is nothing wrong with a PB and it makes me feel better not having to stick gold plated or platinum cups on the end. I have thought about selling my checks to those outfits that buy gold, they must be gold or unobtainium! :groner:
The best thing to do is to ignore book velocities, find what shoots good and leave it at that.
I see it with new archery equipment too. Some bows are rated at 340 fps today. To get that, you need an arrow that does not weigh anything but more important, they are miserable killers of game and it is luck if anyone gets 6" of penetration even in the ribs of a deer. The new bows are wonderful if you just increase arrow weight and be happy with 240 fps, they will penetrate and kill anything then.
Apply the same thinking to boolits. A good boolit is a good killer even if slower then what the book says you should get. The quest for all the velocity you can get is counterproductive.
I run into that with my 45-70 BFR where the boolit MUST be hard and shot fast for accuracy. It is a miserable deer killer but by working with alloy and a hollow point, I made it work. Babore was a great help with his boolits. Unfortunately the softer boolit NEEDS a check. Gas checks must be listed in Obama's budget though. :killingpc
It is at the point that if you drop one on the floor, you will get a flashlight and spend 15 minutes to find it! :kidding:

"It is at the point that if you drop one on the floor, you will get a flashlight and spend 15 minutes to find it!"

That made me laugh out loud because I found myself doing it the other day! Carefull 44man, you are turning into a frugal Yankee. :D

[Ekalb2000]

44man, I am in no way wanting to push these boolits over 1300. Its just that with some of the load data out there, I was wanting to have the option of more than light loads. The occosional barn burning barrel leading hunting load will be alright, as long as it puts meat in the freezer. But for personal and home defense, I dont think to many bad guys wear armor that would deflect 1200fps.
At the end of the day, accuracy is the main objective. I am just hoping to get there without a gas check.

Pics of GPs would be great. I'm in the market for one.

Katie's 4" and My 6" half lug.

Sam :D

[targetshootr]

Nice. I'm trying to trade into one.

[shooting on a shoestring]

Targetshootr...thats a good market to be in. I've had mine for little over a month now and I'm throughly impressed. Got a used 4 inch SS GP100. Shoots good for me. Means 358091s over 1500 fps (enough 2400 to make Elmer sit up and notice), between 2 to 3 inch groups at 25 yds, sitting on the ground, back against a post.

I've promoted it to bedside duty. Hope you get one.

Ekalb2000...I agree with 44man to an extent. However, I have no qualms about putting the hammer down on plain based .357s for defensive loads and going for flat out velocity with some good boolit weight to boot. There I don't need tight groups at long distances, I just want lots of power over a short distance. I get happy on the other side of 1500 fps with 150 or so grains of good ole plain base boolit. Fast wadcutters are my favorites!

Great thread. Thanks. The cylinders look about as big as my 586.

[TCLouis]

Two loads, one boolit and it is inaccurate. Not to be smart, but I think the acuracy issue will e resolved with some on "load development.

As far as leading in a new gun that is possible, many folks recommend several hundred jacketed slugs down the tube to iron out imperfections.

No ability to review issues with boolit hardness, sizing, and the velocity might be a tad high unless the first two are correct.

My GP100 does at best ok so far with three different loads, but pales in comparison to my Redhawk and Super Redhawk. I hope I will find a load sooner or latter that will really make it sing.

So far my best results with real 357 loads have all occurred using 180 grain bullets/boolits and Lil Gun or 296. 3.0 Red Dot and 158 boolit did best in a 38 spl case.

[Ekalb2000]

Nope, two loads, two different boolits.
The 125gr was going to fast. I knew down deep that it probably would. Especially with alox. I have never had luck with it unless there was a gas check involved. That is why alox will be reserved for my rifle loads.
The 158gr with my lube shots great with no leading.
As far as shooting jackets down a brl before developing a lead load, I say bogus. The proof is in the pudding.
Boollit hardness: Brinell hardness tester. check.
Sizing: Slug brl, size accordingly. check.
Velocity: no crono, but no leading. check.

I dont care much for the grip. Going to try and find one of the wood pnl insert grips that used to come on them. Its a tank.
