[QUOTE="Augustus, post: 660774, member: 10142"] 30 in, I fired a few rds yesterday to see how fast the 425s could be pushed. 140 gr of BMG gave 2830 and 2826, extraction was good and there were no signs of excessive pressure. I also fired 145 gr of US869, velocity was 2950 and 2966. Pressure seemed to be ok but this is approaching max. I did push a little harder with 147 gr of US 869. I only fired one Rd. Velocity was 3001 fps. A new pc of brass was used, the Rd extracted ok but there was perceptible resistance. The primer was flattened a fair amount. DON'T DO THIS FOLKS, US 869 has a habit of spiking quickly with very little warning. Anyway pushing a 425 gr bullet at 3000 fps is hummin. [/QUOTE]
