QL request 25 Creedmoor with RL17

BruceP · Sep 14, 2018

Requesting more help for the 25 Creedmoor. I have so RL17 coming to try with Nosler 100gr BT and also the Hornady 110gr ELD-X

The case is 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.
The Nosler 100 gr. BT is loaded to col of 2.685" and the Hornady 110 gr. ELD-X is loaded to col of 2.697".

It would be great if someone could run these combos for me.

Thanks
Bruce

You didn't specify a barrel length so I ran 24.
Also the 110 ELDX isn't in QL yet.

Code:

Cartridge          : 25 Creedmoor
Bullet             : .257, 100, Nosler BalTip 25100
Useable Case Capaci: 46.997 grain H2O = 3.051 cm³
Cartridge O.A.L. L6: 2.685 inch = 68.20 mm
Barrel Length      : 24.0 inch = 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 60000 psi, or 413 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.

I found the following load in some info on-line from the developer of this cartridge (25 Creedmoor/257 Wildcat/2Fity Hillbilly)

44.7 gr IMR4451 with Hdy ELD-X 110 gr bullet coal 2.784" for 3101 fps

Thought you might be interested.

Got this powder and bullets and am going to use in my 250 AI (case cap. 51 gr) and work up a load.
Should be very close to the same performance!

Thanks for the charts that will help with the 100 grainers. I new I was leaving out something. The barrel is a 16" on an XP100 but that's ok. I would guess 250-300 fps less maybe.

Blkram I don't have IMR4451 right now but that's interesting and should perform well. Is the water capacity of your 250AI case with the water mounded at the case mouth or just to the base of the neck?
