I am not trying to be smart but would somebody explain to me why you guys are throwing 400 + grain bullets and complaining about recoil ? What is your need for this . I cannot imagine what a box of 400gr’s are compared to the 300+ Gr’s .i like the .45-70 for the bark and recoil so I load mine hot, just 10 Gr under the .458 for the .45-70 caliber and powder if that is not enough I go to .458. The above bullet I use is the 300 Hornady and my 300 Gr cast for both guns and I get plenty of bark and recoil all I am asking is for an explanation . Happy shooting
