This is a serious question.... has anyone here ever bushed 50BMG primer pockets to accept LRM primers? I'm quite sure that some of the flashtube experimenters who used to frequent this "discussion" board did it, and it's not actually a new idea.....

But I've never done it.
anyone?
alinwa,
With 30,000+ #35 primers on hand,I'm good for the time being(<$60/500 <$300/2500)
50BMG flash holes are .125"/1/8" diameter.
50BMG primers weigh approximately 20grains, other centerfire primers weigh approximately 1 grain.
The LRMag primer sleeve may need to be a cup w/ .075" flash hole, since the BMG primer anvil is quite large by comparison to smaller primers.
209/shotgun primers are NOT rated for any where near bottleneck cartridge pressure.
Sleeve/cup some LRMag primers & load a dummy w/ 215-250gr of BMG (VV20N29) powder w/a wad to keep the powder in said case.
A few grains of 4064(ish) powder under the BMG powder may assist ignition.
I'm still waiting for you to find out how much bullets cost... Oh, and ~17 rounds per pound of powder... ;-) **Everything** is bigger in the .50 world - especially the prices!

The bullets I use are currently $4.00-$7.00 each
Nothing to do with bushed primer pockets. Just thought that might be interesting to some.
I have a friend that makes his 50Cal bullets using 300 Winchester mag case as shown in the first picture and the second picture shows a loaded round, he has shot them in 1000yds match. Turns off the belt fills the case with No. 9 shot then topped off with a 22-bird shot then points it up.
The third picture is a 50 BMG, then a 20mm case shortened and necked down 50 Cal. McMillan they had a single Shot rifle that shot this round.
Tom Martin gave me this round 1991 He was McMillan shop foreman.
