Has anyone really reached published velocities? I am maxing out at 3256 with 180 gr Swift Aframe with 98 gr of Retumbo and this is with a shilen match @ 28 inches. These loads were chronaghraphed while I was breaking in the barrel currently at 10 shots. | ||

I'd try Reloader 25 with the 180, or perhaps even better, N570. N570 gave me the best accuracy with my rifle with 200grain projectiles, but not chronographed....but I reached a safe maximum load as per the VihtaVuori manual. It is a double based 'high energy' powder and they do tend to give higher velocities than their normal powders....... They list a powder charge of 100.9grains as maximum for their 185 Scenar bullet (match hollow point) for a velocity of 3356fps......... Verbera!, Iugula!, Iugula!!! Blair. | |||

Blair, I can't get N570 in the states. Is it a large grain powder? AIU | |||

Not as large as say IMR 7828, AIU. I've seen it advertised in Precision Shooter?........Bruno's; I think......... Same burn rate as Retumbo, just more energy and better accuracy. Verbera!, Iugula!, Iugula!!! Blair. | |||

Well a 180 grain bullet going 3200 fps is going to kill pretty much anything it hits inside of 1000 yards. I also have a 28" Shilen Match bbl on mine. Shilen did the work. I've read that Shilen bores are a little tighter so you may not get published max powder charges b4 you start to see pressure signs. I'm shooting 89.0 Re25 with a 200 grain bullet and trajectory is impressive. Don't know velocity. I may try to find some N570 and try it. Ted Kennedy's car has killed more people than my guns | |||

I use H1000 for my 300 RUM and I get 3266 fps with 180 scirocco bullets and 3220 fps with 180 noslers. I use 96 grs. | |||

H1000(2217 in Oz) worked very well in mine with 168 TSX's but RE-25 just shaded it for accuracy.......... Verbera!, Iugula!, Iugula!!! Blair. | |||
