Biggest thing about going structural is either joining a big big dept or finding one that covers the ghetto. Poor folks love settin their shit on fire. If ur a fireman in a rich area you aren't really a fireman.
Everyone claims blackhorn 209 gives the best consistent accuracy. It's not cheap tho. I've done fine at my ranges with the white hot pellets.
I've never shot at 200 but I would make sure your gun can handle the 150grn magnum loads and if not I would get one that can. I have the cva optima v2...
I been shooting 3 50grn white hot pellets for the last 3 years and i have had 0 issues. I do have a jug of 209, is it even worth switching?
What's the differences between measuring with weight / volume?
