Hi,first of all I would like to here everyones recommendations for powder.
Secondly I need corresponding min and max charges for 300 gr partitions as well as 300 gr Hornady roundnoses.I plan to use these for moose,elk and grizzly.I will be using a Interarms mark x with a 24" barrel,scoped with a 1.5-6 4200 elite.Thanks guys,this site is better than a dozen manuals.Cheers.

A classic load for the .375 is 77 grains of W760 or H414 under the 300 grain Hornady roundnose. The book lists 75-78 grains. It also lists the same charge for every bullet from 270 to 300 grains so there isn't much to remember. My 2 .375s love this load with 300 Hornady RN, 285 Speer Grandslams, 270 and 300 TSXs, 270 and 300 grain Barnes banded solids and 270 grain A-frames but oddly won't shoot the 300 grain partition at all.
 
My son in law was kind enough to loan me his custom 375 H&H, to 'play' with. It was nicely made, based on a Sako action and there were a number of loads I tested through it. The three main bullets I used in it were the Sierra 300gr SBT, Hornady 300gr BTSP and the Hornady 300gr RN IB. As I didn't know exactly how long I'd have the use of the rifle, I started from what Sierra has listed as their accuracy load. With the 300gr bullets, their accuracy load is using IMR 4064 and I wasn't disappointed. It worked very well accuracy wise.
 
There is no substitute for a good set of reloading manuals. What works in rifle A may not be safe in rifle B.

That being said you state you need reloading info for Nosler 300gr Partitions. Nosler lists all the info you'll need right on there site. http://www.nosler.com/index.php?p=15&b=375cal&s=335

You'll have to figure out how to click "300" on the right side, to pick a 300gr bullet yourself.

In addition, if you read the top of the Reloading forum, which your in, theres "Stickys" You'll find a link to http://data.hodgdon.com/cartridge_load.asp

Lots of starting loads there.

Last but not least, both "375" and "H&H" Are not under gunnutz minimum character search, so try..well..a search.
 
I have tried both these sites previous to posting.I have also searched previous posts and misc. sites on the net.I am not a newbie to reloading,just the 375 H&H.I was hoping for insight from members of this sight in regards to their experience with different powders and possible performance results.I do own some manuals, albeit maybe not as up to date as I would like.Other people's experience can be invaluable and something I would appreciate greatly.Thanks to those who respond.Let me know what has worked for you.Hoping this will be versatile for grizz,elk and moose.Cheers 'Bandit.
