J.C.,

Welcome to the forum.

The .25-45 Sharps seems to be gaining a little ground in popularity as folks realize how easy it is to load ammo. It offers quite good performance for such a small cartridge.

Sharps has a chart located on their website that lists load data. Your 16" barrel should produce a little less velocity than the readings in the chart.

If your barrel came from SRC then the data should be good to use.

I have used the Sierra 90 gr. HPBT in my rifle and have found it to be very accurate. I think you could reduce the 87 gr. powder charge from the chart and work up to a good load.



Mike

Good Idea Mike.

I have read the data posted by SRC. I agree with you that useing this
data for the 87gr and reduce the load for a reasonable result. I
sacrificed velocity for weight savings and handling so this is why I went
with the 16" tube. If I can squeeze out close to 2600fps I will be in good
shape. Currently have 100 empties in the tumbler now. Will keep some
updates of my successes. Thanks for the reply and support.

Hi Falcon,
Bear in mind, mine is a bolt gun.
Just to see, i upped my load of 25 grains R7 with the 90 grain GK to
25.1 and then 25.2.
These are the figures for 3 shots with each load: First 25.1: 1, 2989. 2,
2969. 3, 2996.
Next 25.2: 1, 2982. 2, 2989. 3, 2996.
As you can see, there's nothing to choose between the two loads.
Perhaps at the point of deminishing returns?
I've loaded 3 more (Not fired yet) with 25.3 grains R7, just to see what
happens.
These are with CCI BR primers. I will try CCI 450s IF i ever find any.
My testing started with H335, but, after using R7 I won't change powder
again, unless incan find some Xterminator.
Ken.

Ken,

I think you may just be at the "point of diminishing returns". If you can't find X-terminator, you might look for AA2230. They are the same powder.

Hi Buffalogun,
A2230 is just a rumor over here, same as xterminator is becoming.
Thanks for your input.
Ken.
