I shoot 120 grains of B209, a 250 grn SST(regular, easy-glide was to loose), & a CCI mag primer. I could back off the powder some but I've been using the 120 lately. If you find those easy glides to loose you could just get some other sabots made for the .451 bullet. I used some Harvester with the SST bullets & traded away the easy-glide jackets. I also shoot a Lehigh Gen II breech plug. It will fit right in your gun, no plastic jackets,much cleaner, & the channel is supposed to be optimized for B209. They are about $39.50. They will also give you better ignition when using less than mag primers. Your trigger is adjustable. I recently upgraded to a Leupold vari-x-III 1.75-6pwr scope. I just shot last week & I'm right in there, ready for the IL deer hunt.
