How fast can the various bullets be pushed? The highest velocity I see in any of my manuals is 1500 fps. That seems pretty weak considering I can get 1400fps from a 6.5" BH .41 Mag with Cor-Bon factory 265gr loads. I have seen posts on here referencing over 1800fps for .44 mag rifles. Does anyone have actual chrono results for .45 Colt rifle loads? Thanks
.45 Colt velocities from a 20" 1892
1 - 14 of 14 Posts
I just checked the Cor-Bon and Buffalo-Bore web sites. They get around 1300fps for 325gr bullets from a 6" pistol. I would think these loads are as hot as one would want to go. So the question is, how fast will they be going out of my 20" 1892?

Send a note to either of the companies, I'm sure they will be willing to help. Should have their email links on website. I have traded email with both on different subjects.
Recognizing that they are the best authority, I'd suggest a gain of 300-400fps with the 30,000CUP loads going from a revolver to a rifle.
Hope this helps.

I have some chronographed results from a 16" Win. 94 barrel.
335 gr LFNGC
23.5 gr. H110
Starline brass
WSP primers
ave. vel. 1567 fps
ext. spread 19
BRUTAL recoil from the bench. Not bad standing
300 gr. WFNGC
25 gr. H110
Starline brass
WSP primers
ave. vel. 1642 fps
ext. spread 28
About the same recoil as the above load.
Both loads had a maximum crimp and once fired brass from the same gun, neck sized only.
These loads are as hot as I am willing to go. They both gave approx. 1.5" groups at 50 yards. The accuracy probably would have been better If the trigger pull wasn"t so hard. It is getting better with use.

Have you guys seen Paco's articles over at sixgunner.com? He has some pretty big numbers for his handloads. I don't plan on going as hot as he does. That would be why I have 2 .45-70s and a .444!! Just looking for the load that appears to be were you are. Around 1500fps plus or minus a little.

Have chrono-just need gun!!!

I'm going to have alot of data for you here -hopeful within a week just have to get my new toy- on order should be her Monday-16 Sept! I got a Trails End coming-couldn' t get a Legacy like I wanted- know one had any. Oh well, Trails End should be fine. But I really wanted that Legacy
As soon as I get it I'v e already god the loads made up for it.
1 255 gr 23.5 grains H110/W296 also have some Corbon 325 gr. I let you know how it goes.

I got my new toy yesterday, love it!! I forgot to bring the chrono results with me but genrally I saw a 400 fps increase over my SRH 71/2" barrel in the 20" Trails End.
230 gr , 7 gr Greendot load Avg. 1308fps- 2' Group at 40yds
255gr, 7 gr Greendot Avg. 1331 fps-2' Group at 40yds
These are the only loads through it as of yet I did load some with 19.5 gr W296 with 250 gr XTP's , I'll let you know how they shoot- raining today don't know if i'll get to the range.
I also ordered a 300 grain mould so as soon as it gets here we'll really start to have fun!!
Well I did get out today inbetween rain drops The 250 XTP load from above Chrony's in the low 1600's but the suprise load was 255gr FN Cast, 23gr H110, Buff. Bore brass, CCI350
This one Chrono'd at 1913 FPS avg , ME 2042 Ft.lbs Accuracy was 2 1/2" at 50yds

Chrono'd some more rounds!!
Gntlemen
Here is some more data from my Win94 20" barrel.
Buff Bore 325 gr Vel 1798 FPS avg , ME 2334 ftlbs at 150 yds still has 1302 ftlbs! Kicked pretty hard to !! Need butt pad if you shot these allot!!!
250 gr XTP's 20.5 gr W296 CCI350, OAL 1.595
Vel. 1819 FPS avg. ME 1837, 50 yds 1414, 100yds 1264
I'll post the results of the 300 gr cast when I get the mold
should be here next week-hopefully should shoot great with out as much punishment as the Buff Bore's. should be able to get these to 1850 FPS or so.

For those of us engaged in developing loads for 45 LC and 454, try to include some Hodgdon Lil'gun in your testing. In rimmed pistol cases over 15 grs water capacity, it duplicates H110/W296 velocities and much lower pressure in bbls 7 inches and longer. For example the 454 Cassull, 7.5 inch bbl, a 260 JHP does 1900 fps at 54,000 CUP with H110, and 37,000 CUP with Lil'gun (Hodgdon 2002).
For the 45 LC, 7.25 inch bbl, Hodgdon lists 1410 fps for a 250 gr XTP at 29,800 CUP (Lil'gun 25.5 grs). I forget what the CUP spec is for different lever guns in 45LC, but there may be a fair amount of room to grow here, particularly in the 20" bbls.
As bbl length grows, Lil'gun will actually exceed H110/W296 veocities at safe pressures.
If you really want to go FAST, I am developing Sabot loads for my 454 Casull using Knight high pressure .451 sabots and a full range of .40 caliber bullets. I am reluctant to provide data here yet, as there are a few details to work out. Lets just say that I am certain that this approach will yeild more than 2000 fps with a 155 gr Gold Dot in a 20 inch bbl using 45 Colt brass at moderate pressures.

When I called Hodgdon about Lil'gun, they said that it was a "new technology" powder, originally developed for the .410 shotgun. Its close to H110 and 296 in burn rate, but Lil'gun burn rate is less affected by pressure than conventional powders. This makes it more likely to burn all the way down the barrel, even though it is relatively fast. Its also easy to ignite, and works with reduced loads.
I am just beginning to work up loads with the 454 Casull and Lil'gun, and it does give me 50 fps more than H110 at max with 260 gr jacketed bullets. Once I reached max, velocities went DOWN as I increased the loads a few grains. I don't think it likes compression.
In my 7.62X39 carbine it is a star with .312 pistol bullets, easily achieving 2800 fps from an 18 inch bbl.
In my 357 Mag with 12 inch bbl, it drives 158 gr JHPs 1600 fps at what appears to be modest pressures.
On the Hodgdon web site, there are some promising loads for Lil'gun in the 45 Long Colt for strong actions (Ruger, T/C etc.)in a 7.25 inch bbl.
For example the 300 gr Speer JFP does 1203 fps with 20.2 grs of Lil'gun at 29,800 CUP, so it should be safe in a Marlin lever gun. 240 gr Sierra JHC can go 1489 fps at 29,200 CUP, so I think it is good in the LC.

Just wondering, has anyone built a 45 Long Colt on a P14 action yet. Seems the ideal combo for a 400+ gr. pill from LC with 26" barrel. I have the reamer, action and stock. Will get barrel shortly. Just wondering if anyone has been there/done that.
