Thread: 300 Win Mag thoughts...

It doesn't, there is a reason SOCOM picked this cal for the PSR.

What barrel length to get 2950 in a 300NM though?

The 300 WM is the one that can't compete, figures from Applied Ballistics and my reloading data:

338LM 250 Scenar at 2950 from a 26" tube: Litz G7 BC .308 Elevation to 1200m 11.6 Mils, 990 ft-lbs. 93-95 gr AR2217

338LM 300 Scenar at 2850 from a 26" tube: Litz G7 BC .393 Elevation to 1200m 10.7 Mils, 1640 ft-lbs. 92-93 gr AR2217

300 NM 230 Hybrid at 2950 from ?? bbl length: Litz G7 .368 Elevation to 1200m 10.3 Mils, 1255 ft-lbs. 80-83 gr AR2217

300 WM 230 Hybrid at 2660 from a 26" tube: Litz G7 .368 Elevation to 1200m 13.1 Mils, 944 ft-lbs. 72-73 gr AR2217

I added energy because I like to kill things way out ther'

Nice mate I always knew there was a reason I've never had a winmag haha

The Norma velocity was from my 26 inch Trueflite tube which also had the 215's going 3080
