that's understandable .... for the most part, Henry rifles are hunters .... hunting rifles are seldom required to fire several rounds in a hurry so they aren't usually designed for the volume of rapid fire common to AR type rifles .... consider the fact that bullets out of our 26 year old Remington 700 BDL chambered in 300 WBY Mag are pushed by
84.5 gr of IMR7828 and bullets out of our Henry 45-70 are loaded with
51.5 gr IMR 4198 .... the heat generated by each round has to be significantly higher than bullets our Henry 44 Mag loaded with
21 gr W296 .... presumably, each is designed with that in mind .... the barrels in all three get hot but for the task I expect them to perform, I couldn't be happier

Sounds like maybe never, or do you think it's just your 44 Henry that's unaffected?
no clue .... we have long range rifles but all of our local ranges are limited to 100 or so yards .... from decades of experience with our Browning BLR 308 I do know that its 100 yard groups will expand a bit when the barrel gets hot .... when its too hot to comfortably touch, it will string to the up and right .... as with Henry, its a hunting rifle and for that use its performance is exceptional .... because I really enjoy firing our 44 it gets a good deal of use .... the magazine of our BLR holds 4 rounds, the magazine tube of our Henry holds 10 .... consequently, the 44's barrel usually has less time between shots to cool .... as a matter of appearance, the diameter of 44 bullets can create interlocking holes that would be separate holes with 30 caliber bullets ....

we only use RCBS dies .... that is purely a matter of preference .... the first dies (38/357, 44 Mag, 30-30, 308) I purchased back in the early 60's were all made by RCBS .... we still use them today .... not to say that other brands wouldn't deliver equal service but if it ain't broke, I seldom change what works
