QL 25WSSM Barnes 100 TTSX

MAinAR · Mar 10, 2015

I have been loading Barnes 100g TTSX in 25wssm with N550 per Barnes data and it shoots great, but have not been able to get any in a while now. Thinking on a powder change. Have been using Barnes data of COAL at 2.26" Kinda wondering on RL17 or H4350

20" barrel
Fed215M primer

Could someone help me run best powders for this lil rascal. Makes pressure really quick so afraid to just start with comparable burn rates.

Cartridge : .25 WSSM
Bullet : .257, 100, Barnes 'TTSX'BT 25734
Useable Case Capaci: 46.636 grain H2O = 3.028 cm³
Cartridge O.A.L. L6: 2.260 inch = 57.40 mm
Barrel Length : 20.0 inch = 508.0 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 63000 psi, or 434 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 !

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

Thank you! I thought RL17 would be the way to test first, just wasn't sure how much to start, needing to get back to 3,140fps if possible and looks like it may just do that, starting at 42gr and see where it goes.

wildgene · Mar 10, 2015

....I've had very good MV's/ accuracy w/ RL-17 in my .25 WSSM, but I don't load many 100gr. bullets, mainly 75's, 87-90gr., or 115-120grs. Alliant shows the 100gr. Speer SP @ 3300fps over a max load of 47.5grs. of RL-17, for about 125+fps gain over most other loadings. My data & an article by John Barsness (Rifle 1/11) seem to back this up, the .25 WSSM is one of the cartridges RL-17 works very well in...

I have had great results from my 25WSSM using H4350 and H4831sc (using Fed210M primer) behind a Nosler 110g AccuBond...

Could I get you to run this QL table again with 22" barrel?????? I was wrong on the barrel length!

Sorry for mistake!

It does not alter charge, of course.
