Need some help from someone with Quickload

[peterf225]

Can anyone with quickload give me a ballpark idea of velocity of a 105 Lapua powered by 38.5 gr of H4350 using a cci 450 out of a 26" barrel temp 92 degrees and an approximate elevation of 50-100'. Caliber is 6x47L. Any help would be appreciated. Thanks, Peter.

Pete , I have four different 6x47 listed . only two of these has enough case capacity to hold 38.5 grains of H4350 .

6x47 hot (cartridge length 2.800 ) 54904 psi 3016 muz velocity

6x47SM (cartridge length 2.598 ) 66039 psi 3134muz velocity


6x47ATZL ( cart length 2.480 ) 693792 psi

6x47 6-222rem mag ( cart length 2.485 ) 651924 psi

Thanks for the information Jim. I believe its going to be very close to the 6x47 hot you have listed. I talked to a good friend of mine who has a 6x47Lapua also and he said his is running right at 3000 FPS using the same exact load.

Thanks again,
Peter
