I really like B209 in the Knight Elite, luckily I have a few containers from the $35 days. I think it keeps pretty well. I normally just shoot getting ready for the deer hunt. If I was shooting more in the off season, I’d use something else.
One can also drop the charge some, minor savings. I normally use 115 grains volume for hunting. Years ago, 80 grains on a youth hunt worked fine.
