Has anybody chrono'd this load ....

[J Miller]

Has anybody chronographed this load from a 20" or 24" barreled rifle?

45 Colt:
22 grs H110, 300 gr cast bullet?

Just curious what the results from a rifle is.

+ 300-400 from your 7 1/2" pistol.

[TedH]

I shoot that exact load in my 20" Win. Trails End. It runs 1625 fps in mine.

Scratch that. I checked my notes and then remembered that was 23.0 gr. which is a tad over max data for a 300 gr. jacketed bullet.

[adirondakjack]

Lee 300 gr GC bullet, 21.5 H110, seated to shorter OAL, 1475 fps from a 24" Marlin. The same round ran a tiny shade under 1300 fps out of a 7.5" BH.

[J Miller]

OS,

The problem is, I don't have a chronograph so I have no idea what it's doing from my 7.5" BH.

TedH, A-Jack,

Thanks guys, just what I wanted to know.

These velocities put this load in the same category as the 300gr bullet load from a 45-90. That moves out at 1554 fps. So much for nonsense you can't hunt with a .45 Colt rifle.

Joe

[gundownunder]

you can't hunt with a .45 Colt rifle.

I've hunted with less, and I seem to recall history telling us that people hunted with 45 cal round balls in flintlocks before cartridge guns came along and with sticks and string before that.

Joe, I think its way past time you picked a better class of idiot to listen to, otherwise you'll end up trading all your rifles on a howitzer so you can have an effective gun for hunting rabbits.

[Hobie]

I couldn't find where I'd chronoed the load in my Rossi carbine. At least I didn't record it. 300 gr. over 23 gr. H110 goes over 1680 fps. I think it does go over 1550 fps and you're right, it is the .45-90 BP in a short light rifle.

Bob,
That was an attempt at sarcasm . Kind of like we throw back at those who say the 30-30 isn't powerful enough any more.
But a howitzer, now that's an idea. How about this one?

Think that would do for bunnies?

Hobie, I know this must have been common knowledge for many people, but I was sitting here letting my brain idle in neutral when all of a sudden I just had an epiphany. That load is supposed to do, like OS said, 300 to 400 fps more than a handgun, so if that load does 1200 from a hand gun then that added velocity would push it over 1500 and ...... Duh ..... that's 45-90 level of performance. I got me a condensed version of a big bore lever gun here.

Now, what to do with this info? I gotta check to see if this load is accurate from my rifles, then well I just gotta go shoot somthin.

Joe

[Rimfire McNutjob]

I don't have your exact bullet, but I ran a QuickLoad test with the RCBS 305 grain cast for the .45 Colt using the specified powder charge and I got about 27kpsi and 1500fps from a 20" barrel. Obviously that's just a ballpark because I don't know your OAL or your exact bullet config, etc.

[J Miller]

The bullet I'm using is on the right in the pic below:

Lee 255 and 300 RF.JPG

They are seated to 1.562" COAL. I seated them sort to reduce the space between the bullet and powder.

Joe, I remember the first one I touched off in the Marlin quite well. I was well used to 250s at 1500 fps, but stepping up to the Lee 300 (which actually weighs something like 318 as my buddy cast em, harder than woodpecker lips and quenched), got my attention pronto. It also reminded me of the limitations of a peep sight when wearing BRAND NEW eyeglasses (that day), which I scratched with a little love tap from tne tang-mounted Marbles.

Then I ran a few through the 7.5" BH, wrists rested on a fence rail and thought "not bad" but yeah buddy they torque it a bit skyward (I did wear my padded palm, chopped fingers bicycle gloves). Just fer grins I loaded the last round in a 5.5" Vaquero and one-handed it (forgot the glove too). That one bloodied my knuckle but good.

[J Miller]

I fired some loaded over 21.5grs last time I was at the range. I've got the old XR3 grip frame on my BH and that is a hand full. Not bad enough to be concerned about, but you best not let it get away from you.
I fired 5 or 6 from my Win 94 AE and you're right, they do get your attention. The Marlin "should" be a bit tamer as it's got the 20" octagon barrel rather than the 16" skinny round one.

Should be interesting when I get to the range.

Joe

Ah, that's the one with the really wide meplat. Ok then, 25.4kpsi and 1490fps from a 20" tube is the estimate. That big metplat means there's more lead forward of the case mouth and therefore a bit more powder space ... obviously. So the pressure is a bit lower in this new estimate even though I shortened the OAL to your 1.562". It shows the case as being 96% filled.

I'm using a case length of 1.266" and a water capacity of a fired case of 41.6 grains.

96% filled sounds pretty close. I did quite a bit of measuring and there seems to be quite a bit of space between the powder and bullet when it was seated long. That's why I seated this batch deeper.

Joe

[gundownunder]

That looks like a really useful lump of lead. It would be interesting to see how far it would travel through a sizable animal such as moose in US or camels in OZ.
Lee lists the 300 gr GC as having a BC of .233 and with the Pointblank ballistic calculator I get the following figures with a 1500 FPS starting load.
1499 FPE at muzzle, 1002 FPE at 125 yds, and with a 125 yd zero its only 3" high at 75 yds and 3.63 low at 150 yds.

and Joe, I know of some rabbit warrens here in Oz were that howitzer would work real nice

[J Miller]

Bob,

Thanks for the ballistic data. So when I get to the range I can sight it in at 75 yards and be good to go out to 150. Coool! I'm actually hoping to use this rifle and load some day. But at any rate it's going to be a different experience as I've never really messed with this heavy of a .45 Colt load.

With that howitzer, one good direct hit and you could have bunny stew for a month.

Joe

[jd45]

Bob, I'm surprised at you! You certainly must know from watching "Monty Python & The Holy Grail" that those rabbits are treacherous, savage & thick-skinned creatures, capable of rending humans limb from limb, unless bribed with lettuce & carrots, of course, don't you? jd45

[gundownunder]

I don't know about Monty Python, but I used to hunt wabbits fer a livin' and I know they can use the force. You aim straight at one and using the force he can bend that bullet around his head with a mere flick of his ear.

[jd45]

Bob, thanx for that info. I wasn't aware of it. BTW, if you want several good laughs, see if you can't rent "Monty Python & The Holy Grail". I'll admit it's kinda stupid, but this & their Flying Circus TV series from back in the day is the only British-type humor I enjoy. You might enjoy it, as well. jd45

[CaptainFinn]

For the last three years I've been shooting this same load/bullet combo out of my 20" Rossi Carbine and 24" rifle. I didn't find the recoil too severe, even with the crescent butt of the rifle. The rifle mag tube did walk forward a bit, think I finally got it secure this year.

What kind of accuracy are you guys getting ? My carbine will put three shots inside a 3" orange bull at 100 yards from the bench, the rifle (when the tube stays put) does a bit better--I have a Marble's tang peep on it.

[J Miller]

CaptainFinn,

I haven't tried this load in my rifles ... yet. I've got a couple different variations of this load put together and intend to try them at the next trip to the range.

Joe

[JohndeFresno]

Joe,

For what it's worth - QuickLoad predicts this for a Lee C452-300 cast bullet, 22 gr. H-110:
20" bbl: 1476 fps
24" bbl: 1519 fps

[J Miller]

Thanks John.

Joe

[JohndeFresno]

Always a pleasure, Joe.

Yeah, you need to go HUNTING!

[J Miller]

Yeah Hobie, I surely do. I'm gonna be ready and I'm hoping somebody in MO or IN invites me. Nothing but shotguns, muzzle loaders and handguns here in IL. I don't have any of the first two, and I don't feel good enough about my handgun skills any more to try that.
We'll see what the future brings.

Coming late with similar info. My 20" SS 45 with 23 gr of H110 and a 300gr XTP jacketed gives 1700FPS and about 1849 FP of energy.(associated with a big bullet hole). This load can be found in some literature and suggestion is abt 28Kpsi.. Functions well and doesnot stick or act untoward. Havent tried it in the Redhawk. It is apples and pears comparison, but they are at least similar fruit. I have but stuffed into a limbsaver pad because 5# carbine a nd steel butplate in a bit uncomfortable off bench.

rogn,
Thanks for the data. I've shot a few 30,000 cup 300gr loads from my lever guns and they do let you know when they go off.

I'm beginning to like this load. I can't wait to try it.

I'll bet that's the load that jarred the mag tube loose on your rifle.

Joe
