I have just had an xp 100 built in 25 creedmoor and was wondering if someone could help with some QL calculations. I had thought that using 6 creedmoor load data should be sufficient to start with but have encountered a few issues.
The case is just a 6.5 creedmoor necked to take .257 bullets with no other changes. The brass I have been working with uses small rifle primers and holds 52.3 grains of water. I'm using the cci 450, SMK 100 grain bullet and have been working with RL15 powder but also have RL19, H4350 H4831sc and Varget that I plan to work with. the bullet is seated to a col of 2.682" and the barrel on the xp is 16".

If someone could run QL on this is would be much appreciated.

Code: 
Cartridge          : 25 Creedmoor
Bullet             : .257, 100, Sierra HPBT MatchK 1628
Useable Case Capaci: 47.590 grain H2O = 3.090 cm³
Cartridge O.A.L. L6: 2.682 inch = 68.12 mm
Barrel Length      : 16.0 inch = 406.4 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 59000 psi, or 406 MPa
or a maximum loading ratio or filling of 110 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !

3 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

Dang, now that is pretty cool! Looking forward to seeing some pictures of it. Sounds like a ripper!
 
There is not a lot of info out on this wildcat. I would think it would be pretty close to the performance of a 250 ackley improved. Really like the idea of it. I have always want a 25 caliber. This might be a good one.

I’m betting you could use 6.5 creedmoor starting loads without much issue. Sounds pretty close to the 250 ackly improved. I’d check the capacity, it might be a perfect match

Should be comparable to a 30 degree shoulder 250 I'd think.

First thank you for such a quick response. Yes from everything I have read the 25 creedmoor should be a twin the 250 imp. cartridges. however with the limited powders and bullets I have tried so far (2 of each) I have been getting some brass flow in to the ejector hole (shiny smudge mark) with loads that are roughly 1/2 way from the starting load and the max. load for both the 250 AI and the 6 creedmoor with the same bullet weight. I have not chronographed any of the loads yet. It also could be the brass. Maybe it is softer than it should be at the case head. I have some Lapua brass I'm going to try also.
I was surprised that RL15 and H4350 were not in the list of powders in the chart.
Anyway thanks again.

I thought the same thing but it's not working out exactly as I had planed.

Right now the cheap bipod pictured is not on it and the groups seem more consistent from the rest and brick bag but I picked up a Harris bipod to go on it.
 
On the RL15 and 4350, the fill percentages probably weren’t in the parameters I set. I can run them if you’d like?

Well if it's not any trouble that would be great but I appreciate what you have already done. Since I have not used QL I wasn't sure how it worked or picked the powders in the list. I just noticed that there were powders on both sides of the burn rates so that is why it surprised me that they weren't in there.

I have started loading a few of the Lapua brass to see how it does and am hoping to chronograph a few rounds the next time I get to the range to see if the velocities are out of line with what it appears they should be.

Thanks again.

Looks great Bruce. That’s a really danged cool bolt pistol.

And when it wants to shoot like this then it make it even more cool. Even if the load was a little warm.
This was my best 3 shot group so far but another lower powder charge was still in the .3's

24 Nosler eh?

I guess we can expect the announcement before 3-4 months is up?

Per the interweb
"As you can see in the above drawing, it is a .243 caliber (6mm) cartridge with a rebated rim to .223 Remington rim size and an overall length of 2.26″ meaning that it is designed with the intention of being loaded in AR-15 size magazines. It is certainly based on the .22 Nosler case, but it’s not a necked up .22 Nosler. The shoulder is pushed back and it has a shorter case length giving it 2.7 calibers of space over the case.
If one tries to neck down this cartridge to .224 caliber, then it should become identical to .224 Valkyrie in terms of the case length, case capacity and overall length with the exception (or maybe advantage) of havinga .223 Remington rim."24-Nosler-SAAMI-Standard[1].png
