Just to share because the 221 Fireball is decidedly Not Popular with Cast Boolit shooters...
My Eldest could Not warm up to his 221 Fireball Contender barrel. I think the "fireball" part was unsettling him. We do Not like the cost of Condoms for general Hole Punching... so...Cast got the Nod. I detest that short little neck, and finally stumbled upon a boolit that I obtained from a member here (sorry, Forgot Who, but I can find it if enough interest). It is a 50 gr (weighs up at 52 dressed) gas checked "Spire Point", is how I would describe it... Very pointy...kinda like if ya stuck it in a pencil sharpener!!! In his Contender, if loaded to just cover the top lube groove, it is jammed fairly snug against the rifling, and the gas check is right at the neck/shoulder junction, Being Frugal, I started with 5.0 grains of Unique.. We will probably Not change that for awhile... I will chrono that load, and test at ranges beyond 40-50 yards...after the weather co-operates... Right now... he is Thoroughly Enjoying shootin these very mild/pleasant loadings, up!!!
HTH someone...
