I've pretty well made up my mind that I want to start reloading,because with the prices,and unavailibility of ammo I cant enjoy my guns like I'd like..I have a couple of questions ,..Is there one powder that works well with 222 Rem,250 Savage,and 243 Win,and if yes does it also do good in long action hunting rounds such as 270 Win,or do I need different powder...I have my eyes on two different start up kits,one is Lee precision challenger kit for around $125,and one is Lee Precision Anniversary challenger 2 for about $130 any opinions on these kits ?....Thanks
