hello everyone iam new to this blog stuff. so be kind please. i have a ar 15 a ak 47 a 30.06 for rifles and in hand guns i have a 9mm and a 45. smmunition is getting expensive and i use to own a 44 mag that i reloaded with a single stage rcbs which was great and saved me a lot of money on ammo. but my ex wife took my 44 and reloader. iam looking in to investing in a new reloader, i have narrowed it down to a 550 or a 650 xl dillion, or a rcbs pro 2000 but since iam new to a progressive reloader i would like to get some input to which yall thought would be the best and most easy to change from caliber to cliber i have done some reading and it seems that the rcbs gun powder dispensor or mre accurate and jost one does rifles and hand guns where with a dillion you have to have 2 different powder dispensor for rifle s and guns . i have also read that the rcbs is much quicker to change out from claiber to caliber. please LET ME KNOW HWAT YOU THINK..
