[QUOTE="mcseal2, post: 408172, member: 22030"] Will the 280AI deliver the extra speed from this short of barrel? I have an excellent gunsmith a mile away who could open up the chamber. If the gun wasn't accurate I would put a 24" fluted barrel in 280AI on it right away, but I have a hard time disassembling a 1/2" gun. I did more experimenting with the 280 this evening. I still didn't find the speed I wanted, and none of my loads showed any pressure at all. Here are my results so far for the hotter loads with each powder. All are averages for 4 shot groups. Some loads I worked up to are over max depending on the reloading manual used. All shot between .5 and 1" except one. The air temp was between 85 and 90 the whole time I was shooting. 140gr Ballistic tip 53gr H4350 2810 53.5gr H4350 2832 54gr H4350 2863 (accuracy poor) 57gr H4831SC 2780 58.5gr H4831 2825 59gr H4831 2875 59.5gr H4831 2875 55.1gr IMR 4831 57gr RL 19 150gr Scirocco 51.5gr H4350 2748 The 150gr Scirocco had only 13fps deviation for 4 shots. If I don't find anything better I may have a turret made for one of my Leupolds and use this. Has anyone tried this bullet on muleys at extended range? I have used the Varmint Hunter reticles for several years with good success by keeping my velocities all close to 3000fps and BC near .500 on all my rifles. I like that because I can use the same hold and windage with any of my rifles out to 500. [/QUOTE]
