Page 301 of Lyman's reloading Handbook, 49th ed. states "Pressure limits for this cartridge [44 Magnum] is the same in rifles or handguns." Rifle data lists max loads for H110 and a 240 grn projectile at 23.5 grns. (No pressure listed.) For handguns, the same maximum load is listed and states a pressure of 35,700 cup. For handgun, a 300 grn projectile is listed with a max load of 18.5 grns (again, H110) and 38,300 cup. No 300 grn data for rifle is given.
Using that as a basis for discussion, my question is thus:
1.) If pressure limits are the same in both rifle and handgun, and max load for the same projectile and powder are the same for both rifle and handgun (given a 240 grn projectile), does it follow that the 300 grn projectile data for handgun is equally applicable in the rifle? (I think it is.)
2.) Extending that concept, are max loads using rifle data safe for use in a handgun?
3.) Does anyone know of other, reputable data for 44 Magnum with a 300 grn projectile listing a higher maximum charge or pressure using H110?
