My favorite powder for the 45-70 is H4198...and I much prefere the Nosler 300 grain partitions to anything else...Lot's of guys over at Marlin Owners use the Northforks and swear by them...Niether are what you can call in-expensive...both both are top performers in the field and have taken many elk...The partitions loaded to 2350-2400 fps should work wonders for you,provided you are ready for the recoil..this loading isn't for the meak nor or they trapdoor loads.....I haven't used the Lazer cast bullets...but have used the cast performance 405gr WLNGC bullets...they are very accurate and don't lead up the bore even driven to 2000fps..Lots of folks say you can eat right up to the hole with cast bullets...I don't know...I prefer the bullet to expand and still hold together when it passes completely thru...You'll just have to load some up and try it...I'm quite sure you'll be amazed at the results with the 45-70..It's one of the best NEF offers.If your wanting to try the Nosler Partitions...Cabela's have them on sale right now for $30.00 a box..Don't ty to load the non-gaschecked bullets to fast...they will lead up the bore...and PS...Congrats on the new NEF...
