Nsaqam, Thanks for your help. I have some RL-22 so that is a big help. The Vihtavuori can't be had locally. Ken
I believe I have some of these bullets. Someone from this site sent them to me a couple years ago to try. I didn't know they were sending them, then I moved to another town. The package was forwarded and took literally 3 months to show up at my new place!
Anyone, at that time I forgot who sent them, and tried to remember at the time and couldn't. Belated thanks...
R22 has worked well for me in the past. In the future I'm going to try Ramshot magnum and h4831. Got an action and barrel at the smith becoming another 6.5x55 and plan to shoot the mega out of it.
