ok guys maybe some one can give me a little insight per im fairly new to reloading and chronographing. im using 25.5 grains of h110 behaind a 250 hornady xtp bullet. the min loading is 25.7 grains and says i should get about 1398fps out of a 71/2 inch barrel. well im averaging 1735 out of a 4 5/8 barrel ruger blackhawk. i did a 3 shot average twice just to be sure. is my chrony screwed up or is this just awesome velocity?
45 colt and h110

How far are the screens? The shockwave or muzzle blast can cause a false reading.
Perhaps you could check the crony with a 22 or other gun or a known load..
1735 fps and a 250 gr. Bullet = 1650 ft lbs energy.
1400 fps with the same 250 bullet = 1088 ft lbs. Energy.

Sure does not seem right. Does not agree with Hodgdons results out of a longer barrel. Heck Hornady does not even list H110 in the Ruger loads and the highest they get is 1400 with H4227.
What brand Chronograph, any other loads to test it with. Shoot a 22LR through it.??
Yes you need to be at least 10 feet.

In my experience, you need at least 10 feet, and probably more if possible, to get valid readings with any of these slow powders. The last time I had my chrono out at the range, I was testing 357 magnum 158gr loads and trying to keep the chrono out of the rain. I was getting velocities of 2000fps+.
Hogdon's online data does list W296/H110 for a 250gr XTP under Ruger data. I think their max load is 26.5gr or so.

Yes I looked that up in 1st post. It does sound like the OP is too close to the Chronograph.
ok guys i backed my powder charge back to 24.5 of h110 just in case and got further back from the chrony. i averaged 1065 fps out of my 4 5/8 barrel with a 250 grain bullet.. wich gives me 630 ft pounds of energy. im ok with that. may load up a few with more powder but as for now thats a pretty stout load for me.

Figured it was a chronograph issue.
I realize different people have different goals. And indeed mid 1000's fps is a very useful velocity level for a .45Colt.
And I realize that in our present situation powder selection is often constrained by what is actually on the local shelf.
All of that said , that's a really light loading of 296 . I would suspect you are getting wide velocity variations.
If you have access to other powders , your current velocity level is well served by iconic loads of Unique , 2400 , and 4227 . An additional dozen or so powders will also work well in those velocity/ pressure ranges.
If 296 is the only possable tool in your quiver , you'll get better results by stepping up 100-ish fps.

With H110 in a handgun load I would suggest going to 15 feet. I was doing some chronographing of some 357 Magnum loads Saturday and AA #9 out of a 6 inch barrel was showing some velocity swings of 400 fps or more while the same ammo out of my 1892 Winchester had the velocity nailed at 1600 fps within +/- 10 fps. Since I had the chronograph 10 feet from the bench I can only conclude that unburned powder particles from the shorter barrel were reaching the chronograph and causing false readings. The lesson I took away was that with a slow powder it's best to put the chronograph further downrange.
well the minimum loading is 25.7 grains of h110 so i backed it down a lil just in case. tomorow ill do a batch of 10 to 20 and use the original minimum.
i have unique and imr4227 but no load data for either for a 250gr xtp bullet or a 200 grain ftx bullet. that being said im still using 25gr of imr4227 on the 200gr ftx bullet and getting an average of 1110 fps. wich gives me about 547 ft pounds of energy. i could load it hotter but im going on load data from a 225 gr ftx bullet. so i dont wanna screw around to much. my data is coming from the hogdons website. i think that would be a good deer load. or maybe even used for black bear defense.
These kinds of problems are why I don't like the Chrony brand. I gave
up on getting realistic readings with two of them. Tried everything I
could think of but nothing worked, even moving back about 20 ft.
The 25 acp is a better round than many think but 1800 fps?, naw.

Been using my Crony brand for years. Then one day I shot it. I sent it back to Crony for a replacement at 1/2 price. They allowed me to use the credit to upgrade to a model with a remote screen. Still using it. I bet I have had it for 20 years. I have no trouble with mine if I use it right. Its a great tool.

I'm at a loss as to why so many reloaders want to turn a 45 Colt into a 44 Magnum???
You do realize those "Ruger Only" loads are not SAAMI compliant, right? A 250gr bullet @900 fps will kill anything that walks in North America if you do your part. Why push it?

I tied to post the pdf article of Handloader April 2007 but it will not link.
Do a Googlefu for it and download the article by Pierce. He breaks down loads in 3 sections. Old 45 Colts, Newer ones and the Ruger Contender loads.
The Ruger loads with a 280 gr bullet only gain a few hundred FPS So as Arch says, a big hunk of lead going 900 fps sure seems to be enough!

well if you want my answer to that its because i wanted a 44 mag but already had and handload for 45lc. so instead of going out and buying a 44 mag, brass, lead, and primers for it. i decided to give my ruger bh a little more versatility. these loads arnt being used for target practice. im shooting a few through the chrony and using the rest for hunting. this being said if a 250gr bullet going 900fps will kill anything then why have a 44mag.
