I use 125Gr.ULD Wildcats in 25-06AI, & they shoot great, but I am pushing them at 3,250fps. I don't see which cartridge you are shooting, but if 25-06 & at least a 24" tube & hopefully a 26" tube, I believe they will be fine IF you push them to a good vel. & seat close to the lands, these type
bullets prefer that.
