Goeiemôre, ons het n Howa 1500 in 6.5 Grendel, Nosler Custom Competition 123gr en n ¾ blik S341.
Is die kruit bruikbaar vir die kaliber, of moet ons eerder iets anders probeer?
_________
Is S341 a viable option for the 6.5 Grendel with 123gr Nosler Cust Comp?

I am sure Oom Drie will be around soon with in depth answer. IMO it should be well within the useable range, but my answer is only an opinion based on other cartridge's I have loaded for.
I am who I am - I am not who you want me to be.
Therefore I am me.

Hiermee teoretiese ladings wat 5K psi laer is as maksimum druk en met 'n 24 duim loop. S341 is dan No. 2 op Somchem dryfmiddels se lys.
Cartridge : 6.5 mm Grendel
Bullet : .264, 123, Nosler CC HPBT 53415
Useable Case Capaci: 29.022 grain H2O = 1.884 cm³
Cartridge O.A.L. L6: 2.250 inch = 57.15 mm
Barrel Length : 24.0 inch = 609.6 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 47000 psi, or 324 MPa
or a maximum loading ratio or filling of 100 %
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 80%. These powders have been skipped.
