anyone have load data for 45 colt 360GC?

[demo_slug]

I got some Oregon trail true cast 360 LFN with gas check. I tried 18 grains of H110. but a Can't hit squat with it out of my 5.5 black-hawk. at 15 yards I'm getting a group size of about 2 feet.

anybody have any luck with these bullets? I have a lot of powders and primers to try..

HS6
Longshot
trail boss

From Hodgdon, RUGER ONLY:

15.5 to 18.0 LilGun, 18.0 to 21.0 H110, 19.5 to 22.0 H4227....
WLP primers all, COL 1.680"....(Max loads at 30K level :shock: :wink: )

BTW, a 2' group @ 15 yds tells me there's something wrong besides the load.... :wink:

Besides the Hogdon recipies there is the formula from IMR for using Trail Boss.

360 over H-110 and 2ft groups at 15? Is the recoil so bad that you have to close your eyes before you shoot? :wink:

In all honesty, I agree with Bucks Owin. Something is bad wrong. You should be able to accidentally drop 44's in the chambers and get better accuracy than that.

Figure out how much H110 will fit in the case without being compressed, use a Mag primer, and crimp as tight as possible. That will be your accuracy load.

 

[demo_slug]

yeah yeah. I'.m telling you guys it doesn't shoot straight. I'm normally a very average shooter. and its probably more like a foot. I shoot at a 5 inch bull and the grouping is high and low. I think I'm having some erratic behavior out of the H110. the slow ones go high the fast ones go low.

maybe I mixed in some of my work up loads.

 

[Pal Val]

I would try a few groups with factory ammo, just to get a baseline. At 15 yds, you should be ripping the center off the target with that gun.

18 gr H-110 is the lightest load I found in the book for that bullet. I find that powder gets best results loaded a bit heavier with magnum primers and a firm crimp.

Slow loads going high and fast ones going low is normal in a handgun. If you mix them, you get a vertical string.

 

[demo_slug]

again. I have no trouble with my other hand loads at 15yards. I'm just having some trouble with these new bullets. I've fired thousands of 45 long colt rounds that I've made myself.

Are your cylinder throats the correct size ?

 

[WESHOOT2]

Easier way to ask that question: Do the 360g bullets (actual weight and diameter? You checked, right?) push through the chambers, or fall through?

Start load 17.0g AA9, Redding Profile Crimp die, standard primer.
Also ensure your eyes are remaining open during shooting.

 

[Hammerdown77]

Did you pull ten out of the box and measure their diameter and weight to see if they're uniform?

I guess the question is, has anyone else here had any luck with THAT specific bullet? Maybe it just don't shoot....

 

[Bucks Owin]

My pre warning NM has throats of .455-6" and much prefers it's lead bullet fodder sized to .454". (The barrel is .452") It's accuracy is not great with any factory "cowboy" loads I've tried, running 4-5" at 25 yds. However the WW 225 gr Silvertip HP, which I'm told has a somewhat hollow base, will group 1.5" at that range, as do most any carefully assembled .454" cast bullets over stiff charges of W296. Midrange loads with HS-6 shoot equally well, as do "plinker loads" with Green Dot. The only jacketed bullet I've tried is the .452" 250 gr XTP, pushed to 1350, which while not as accurate as a .454" lead bullet, still gave decent results of under 3".So yes, by all means determine the size of your throats for max accuracy. But with the worst shooting loads I've ever sent downrange, it has never grouped as badly as what you describe with your's....
No disrespect intended, but I have to think it has to do with your shooting technique...(You ARE testing from a rest right? :shock: ) I freely admit that shooting tight groups with hell for leather hard kickers can be difficult. I've had many a tight group ruined with a "flinch flyer". Anybody who says they never flinch either hasn't shot much or is lying through their teeth. :wink: (BTW, a "flinch" isn't necessarily fear of recoil either, sometimes it's just impatience to get the damn shot away after a longish spell of extreme concentration...) Tight groups with a handgun don't come easy. (Except with a keyboard! :lol: ) Keep at it amigo....

throats:
I have 3 guns in 45 colt. but in regards to my blackhawk the throats are not loose. a 451 diameter FMJ will drop right thru all my throats. 452 lead needs a good solid push and it might get stuck.

Oregon trail 360 GC:
the lead is .452, the gas check is .453
the weight of the ten bullets I just measured are 358.2 to 359.0


and I don't have any AA9.

keep in mind, that data is for a Cast performance Bullet. it is not the Oregon trail Bullet. I evaluated that load data when I was making my load.

 

[Bucks Owin]

Excuse my bluntness, but I think you're chasing your tail....(or maybe yanking our's ) Get more trigger time.. :wink:

 

[demo_slug]

ha ha. before you post data, make sure its for the actual bullet.

 

[twobisquit]

Linebaugh likes the 350's but says he considers them maximum for the .45 Colt and .454 Casull.

You've settled my doubts about you...(sonny) :roll:

 

[demo_slug]

thank for trolling up my post. I hope you don't derail guys that are trying to help. got to take the good with the bad.

IF the moderators would close this thread I'd appreciate it.

Go to Oregon Trails website. They are very helpful and will email you their data.

http://www.laser-cast.com/LoadManual.html

I am personally interested in hearing what you come up with.

 

[demo_slug]

when I called them they wouldn't email or tell load data over the phone. but they will mail photocopies of their load manual. they sent me their 45 colt pages. but... this bullet is not in it. I scanned them as PDFs. if you want it PM me.

I have a copy of the Oregon Trail reloading manual and it's worth buying a copy if they still sell it. Thanks.

I noticed an article on obturation when I was looking up their link. They are addressing the problem since a lot of people say it's a problem wit their hard bullets. They say it is not a problem if you keep your loads above 13000 psi.

 

[flatgate]

You may not be pushing those heavy slugs fast enough for them to stabilize.

I shoot lots of 300 gr. and 335 gr. Gas Checked bullets out of my Ruger .45's. Velocities are in the 1200 fps range. Groups are as tight as I can "hold the gun".

In fact, John Linebaugh states this about heavy slugs:
"350 GRAIN SLUGS ARE THE HEAVIEST WE RECOMMEND IN THE .45 COLT.
THIS IS ABOUT THE BALANCE POINT OF THIS ROUND."

JMHO,

flatgate

 

[demo_slug]

got the data from oregon trail in the mail today. my 18 grains of h-110 was below their start load by half a grain and they specify a CCI 300 primer. I don't have that primer.

but they do have a load specified with with no start load>
CCI350s and 20.0 grains h-110, starline case. at 1213fps out of a 7.5 inch Bisley. I can follow that recipe and I'll give it a try in my 5.5 and maybe in my 24 inch 1894..

 

[pvtschultz]

Like others have mentioned, H110, W296, and Lil'Gun tend to really shine when the case is FULL but not compressed. Of course, always work up and exceed max published loads at your own risk. The accuracy tends to suffer when there is air space in the case with these slow pistol powders, and those bigguns probably need to get pushed along at a good clip in the 45 Colt to stabilize.

 

[Luckyducker]

Demo Slug, I have loaded the 335 grain GC Leadhead bullet in 45 Colt with 23.5 grains of H110 with decent accuracy. I started low and worked up to this power level and while running the test loads over the chronograph the velocity was all over the place until I reached this heavy load and then it settle in with very low ES. Most of these will run 1292 and 1293 ft/sec with a few running 1290 to 1308. I think your load is not hot enough to get it to stabilize, but loading these heavy bullets is kind of like going into uncharted territory IMO.

 

[WESHOOT2]

I found my limit at 350g; the 360g and 395g (which is where I stopped, not feeling any need to go to the 405g) did not stabilize fully for me from my 5.5" Redhawk when tested past 30 yds.
Plus there was that 'recoil' thing.

I feel, based on experience, that the 335g is the maximum successful heavyweight choice in 45 Colt. If one is searching for a close-range creature-defense load ONLY the 350--360g may still be a viable choice.

 

[pvtschultz]

^^^ I'm with that guy ^^^

335 gr of lead on top of a max charge of Lil'Gun/H110 (I use CCI350 primers) and a good grip on the revolver. This one will put the bullets exactly where you point the gun and is my hunting load for this fall.
