A freind of mine just gave me 50 375grain 416 dia. cast bullets to try in my little project, the 416 bear. Thats a nanget M44 rebarreled to 416 cal. and simply a 7.62x 54R opened up ( darn near straight cased). I was considering starting with 52 grains of IMR 4895 as a starting load but I'm not sure if thats a good place to start. Any thoughts?

Sounds like an interesting project!  You might also try 50.0g AA#2495 as well.   Let us know what results you have!  

What are you doing about dies? and Who made the reamer?

God Bless,

Marshall

actually there was no reamer. the machinist used a series of reamers and a boreing bar. the die neck sizes only. The brass is made by pumping up the neck and fireforming.

This topic was moved from Rifle Cartridges:  It better belongs in Wildcat Cartridges... sounds like an interesting project that I want to hear more about.

actually marshall the job wasn't to hard. the only problem is altering the feed rails and box magazine.  As you know, the magazine is now too small in the forward area. I appears that I'll have to fabricate a new one and alter the feed rail extensively.  thats a bridge I'm not ready to cross yet. It might work better to completly hog them out and make a detachable magazine. I made one for a 12 ga pump shotgun once for a customer when i worked in sheet metal. What do you think?

Dear Armedfree...If you will give me the grains of water in the case and the weight/caliber of the bullet...I will run it through the "Powley" and see what comes out...Weigh the empty case..then fill to where the base of the bullet will be. Subtract latter from the former to get grains of water. The calculation will be based on 44,000/45,000 psi, a good working pressure for the M44
Best Regards from The Hammock....James
