I like the 200 gr Accubond. The horsepower is there in the RUM, why not use it? I push them at 3200 fps, using RL-25. As far as temp sensitivity I have been reading about, I haven't noticed any. mtmuley
100g of retumbo? Seems like a lot I chrono'd 100g of retumbo as well it was shooting at 3575 for my first shot and also gave me a sticky bolt... Seems like a bit much pressure to me.... They one shot and done?
I use ar2225 which I believe is equivalent to retumbo. I have been using 180 ballistic silver tips and have tested loads starting at 94gr ar2225 all the way up to 100gr ar2225 and have found my rifle Rem 700p 26"barrel to be the most accurate shooting 100gr ar2225 and the most consistent velocity averages between shots. What length barrel are you getting 3575fps out of? If it's only 26"barrel tripple check your powder weights.
