Default 218 Mashburn Bee

I Swore that I was never going to buy another rifle - or gun for that matter. And I swear that this Cooper 38 in 218 Mashburn Bee is absolutely the last rifle I will ever buy. Really!
My problem is that there seems to be little loading Data for his cartridge. What little I've found is with IMR 4227 and IMR 4198 powder. The loads such as the one used by Cooper is just a hair above 218 Bee loads. I have two other 218 Bees, one a Ruger #1 and the other a Winchester Model 43. Both are most accurate with a load of 14.2 grains of Reloader 7 using a Federal 200 (small pistol Magnum)primer.
But I digress, I suppose that I'll do what I always do with something weird and work up loads slowly. However, if anyone has any advice to share I'll be happy to not reinvent the wheel. Thanks in advance.

Bob

Default Mashburn Bee

I've found with mine that any 218 Bee max load is a good starting point for the Mashburn. My experience shows that you'll only get about 2-3grs over std Bee max capacity before velocity flattens out and pressure issue's surface. I've also made brass out of 25-20 for mine and although the necks are a little shorter than brass made from Bee brass I see no difference in brass life or accuracy. Some guys will tell you that the 25-20 brass shows a lower Saami pressure rating. Others will say that was because of the rifles designed for that chambering in that time period, similiar to the 257 Rbts. My load is 17.2grs of H4198 with a 50gr Vmax out of a 26" barreled Martini. I've tried RL7 and H322 also with good results but the H4198 worked best in my rifle. I do enjoy my Mashburn but personaly feel for the advantages gained, cost of dies if you can find them, I doubt if I would build another.

I like RL-7 in mine, as I can't seem to find any short cut 4198 locally. I've also had some good luck with the Hodgdon Lil'gun loads specified for the std. Bee. I'd like to try some Norma 200 if I could ever stumble on to a stash of it.

I took standard Bee loads and worked up until I got pressure signs
then backed off a little. Was using a 40gr. bullet. IMR 4227 gave me the best
accuracy in my rifles. These are some of the loads I came up with.
15.0 gr. IMR 4227
13.7 gr. H110
16.7 gr. 1680
16.6 gr. VV N120
17.8 gr. RL7
You might want to start a little lower.

Thanks for the information. I went to the range today. Just about perfect weather for shooting here in Kansas City. Shot loads using 4227 and 40 grain Hornady using a small pistol magnum primer as well as ReLoader 7 under 40 grain Noslers and a small rifle primer. Was working up from Bee loads and am not showing any pressure yet. Groups are disappointing - running a little over a MOA for a 5 shot group. However there is a glimmer of hope as some of the groups get smaller as I go up in powder charge.
I can't seat a 40 grain bullet out to the lands with my stoney point tool, so I may need to go to heavier bullets, but I think I'll continue to work with 40 gr bullets but try 4198 and 1680 powders next next trip and also continue to try both pistol as well as rifle primers. I should have known this wasn't going to be simple.

I know this is an old post but was wondering how in the world you get 17.8 grains of RL-7 in a 218 Mashburn Bee case. I just got a Mashburn Bee and am loading 16.5 grains and its darn close to being compressed.
