Ok, I need some help. I have a shooting buddy that needs your input for a good load for his .218 Mashburn using a 40gr bullet or less. Im finging out that there just isnt a lot of info on this round.

Hope someone out there can help.

I had one years ago, but sadly it's long gone. I didn't reload for it, just shot factory ammo. Ackley's Handbook for Shooters and Reloaders lists between 16 and 16.3 grs of IMR4227 for a 45 gr bullet, no load listed for 40gr. Hope this helps. http://www.reloadbench.com also has load data for this round. A Google search will provide a whole bunch of links.

i got one in a martini cadet. 16.2 gr of H4227 & a 40 gr nosler. in this rifle it is a very accurate load & shows little pressure

Tell him to look at 221 Fireball data to start off with.
Have had great success with the Winchester 46 gr. HP and H4227.

The fireball is a larger case, so I wouldn't use 221 data. You can find 218 bee data, and just tell him to carefully work up from the top loads.

I had one in a 10" contender, and it seemed to prefer the 45 gr sierras. I'll have to dig through my data to see what the best powder was.

Whoops! I didn't mean to say 'work your way up with 221 as a starting point'

What I meant to say was go between 218 Bee and 221 FB. You really can't fit the amount of powder a 221 calls for in a 218 Mash Bee anyways. I would say the FB data is equivalent to a bit over max. for the Mashburn.
