[QUOTE="AZ82New, post: 3027847, member: 120858"] Ok, so I just took out the SAKO 85 that has a 24.3 inch Bartlein 2b. This rifle has roughly 200 rounds through the barrel whereas the 20 inch model 70 with the muller works cut rifle barrel had less than 100. Velocity's: RL 26: 3,089 fps with the 190 Speer Impact. This was literally the same ammo I loaded up the day I shot it out of the 20 inch barrel at 2,810 fps. Staball 6.5, 3,049 fps. This was not loaded the same day but I loaded to the same specifications as before. 140 fps (Staball 6.5) difference makes sense out of 4.3 inches difference in barrel length and a different barrel that may be inherently faster and is fully broken in. Nearly 300 fps (Reloader 26), doesn't make any sense other than that slower burning powder needs more barrel length to perform. I did notice that I was getting heavy bolt lift in the reloader 26 load and slightly heavy in the Staball 6.5 load. I think im probably jamming the bullet in the SAKO whereas the model 70, cut with a different reamer, has a little more freebore . Also, it was drizzling. So there likely was some moisture on the cartridges that was increasing pressure. Nonetheless, there was similar velocity and less pressure with the Staball 6.5 load. Also, what one would predict in difference in velocity with each given barrel length made more sense. [/QUOTE]
