Cartridge : .300 Win. Mag.(W)
Bullet : .308, 190, Nosler CC HPBT 53412
Useable Case Capaci: 83.516 grain H2O = 5.423 cm³
Cartridge O.A.L. L6: 3.340 inch = 84.84 mm
Barrel Length : 24.0 inch = 609.6 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 54570 psi, or 376 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 !
25 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

It's always best to err on the side of caution when changing any component. The difference in bearing surface can sometimes get an individual in serious trouble. As it turns out, the projection with the Sierra 190 grain HP MatchKing and N570 is similar to the Nosler 190 grain CC.

As I recall, for some time, the Navy ran a 190 gr Sierra Match King in their .300 Win mags...
The load has been published, and was effective. I don't know what their load was. Might try searching Snipers Hide for the .300 Win mag Navy load or something along those lines.
When I was shooting the .300 Win mag, I went with 180's first, got hung up on 165's for a while, then went for the 200's in a big way. I still like a 200 gr bullet from a .30 cal magnum. They seem to shoot really well - as do the 190's I've seen and used. SMK's though, I've only used .30 cal Nosler competition bullets in 155 & 168 grains. Very good though.

I shoot 190 SMK's out of my .300 and have gotten amazing accuracy, groups around .2" at 100. The bullets are almost identical after looking at the dimensions. I use 70.4 grains RL-22, Fed215M, and jump them 0.010"
