What ammo and bullet was you using? My 44 mag revolver loves 300gr XTP. Can't buy them but you can reload them. Or try hornady 240gr American Classic I believe its called. XTP bullets have always been very accurate for me.Having some perplexing issues getting my Henry to group well at 100 yards. Best I'm getting is 6" groups. Curious what other folks have experienced accuracy wise with their Henry Big Boy or X Model 44 mag.
Im using winchester 240 gr soft pointsso you shooting pistol or rifle ammo out of that Henry that could be the difference
