Hello,

I would like to start shooting cast bullets in my 577NE. I have a fair bit of experience using them in my smaller ( relative term) big bores, however I’m finding it difficult to come up with things like gas checks, sizing dies etc. for the 577.
I would like to keep them in the 650 grain range and hope to drive them somewhere between 1500 – 1800 fps.

Any advise re loads or where to purchase supplies would be appreciated.

BTW, The equipment I presently have will not accommodate this size of bullet...so I’m open to suggestions.

Regards,
NN

I had LBT Veral Smith make three sizes of molds for my 577. A 450 gr, 650 gr and 750 gr. I shoot them as cast. I like the 650 gr the best. The 450 gr are really fun to shoot but with most powders I have had problems getting good ignition. The 650 gr and 750 gr I use around 100 grains of RL-15 and one or two 28 ga fiber wads under the bullet for a gas check. I soak the wads in molten bullet lube to give a good seal and extra lube.

Thanks srose...this is exactly the kind of info I was looking for

If I can ask, what diameter are you casting them?


Thanks

I cast a bunch and figured I needed to size them. I had a custom push thrpugh sizer and cutter made so I could size then put them in a tray of melted lube and then cut them out when hard. I found it was not nessicary to size them and after trying both sized and ascast. Now I just shoot as cast and tumble lube usually even though it makes them ugly. I also use 28 gauge fiber wads but never thought to lube them, I will have to try it.

Oh and I cast linotype for my 577 nitros btw.

As cast my bullets are .585.

All good info...thanks guys.

Sam what diameter are the bullets as cast?

What type of alloy are you using to cast the bullets?

I use wheel weights and drop them out of the mold into a 30 gallon drum full of cold water. They come out pretty hard.

This is a cool topic!
It's an example of why we're here.

I agree

Tom at Accurate Molds makes some very nice molds also. He did a 650 and 750 weighted dual cavity mold for my 600 w/o problem. His online catalog shows several styles for the 577.

Tim @ Accurate has a nice 650 grain that I'm going to order for my 577. He seems to be very helpful as well.
