.450marlin reload

[whiteraven]

Looking for reload data for .450 marlin using bullets larger than 400gr. I have some 425gr hardcast,gas check bullets .459 dia. Have been on-line looking but not much info.also a lot of conflicting info. Would like to hear from anyone reloading for this round. Thanks.:cool:

I can give you a couple maximum loads for the 450 Marlin that was posted on the Marlin Forum site. When pushing these bullets to these velocities/pressure you are going to feel some serious recoil. I would suggest keeping around 1,600 FPS with 420/425 grain slugs. You won’t give up much in the way of penetration but the felt recoil will be much better. If you go up into the 500 grain weights – I would suggest pushing them as hard as you can, because obviously you have a need for that type of bullet, so **** the recoil and go for the gusto. H322 works very well with that caliber and heavy bullets. I will be working up a few loads for the 450 this coming summer using the 500+ grain HC bullets over a chronograph, so if you want, drop me an e-mail around July and I'll share my "black & blue" findings with ya.

Thanks Joe. Thats a lot more than I had been able to get. I hope my memory can last till July. If so I will get back with you. Thanks again.
