I recently bought a RUML and just shot it for the first time this weekend. I have been recommended to use BH209 by the shop that I bought the gun from and multiple friends that have the same muzzy. (I know a lot of people say don't use BH209 because Remington doesnt warranty it but a lot of my buddies haven't had issues yet.) This weekend I was shooting 120gr by volume blackhorn 209 with a Barnes 290 grain bullet and yellow sabot. Im trying to find out fps so that I can get custom turrets made for the Vortex scope I have on the Muzzleloader. Any advice helps, fairly new to muzzleloaders. Thanks in advance!
