Howdy,
I recently purchased a Winchester 71 that had been re-barreled to 475 Turnbull.



I have load data for jacketed bullets from Turnbull Restoration, but am having trouble finding information about loading cast lead bullets. I found a box of 410 Gr. Lead Wide Flat Nose Gas Check bullets by Cast Performance at Midway USA and have them coming. I've loaded for a ton of different chamberings using jacketed bullets over the years but have very little experience loading cast lead.
I'm asking if you guys might have a load your prefer and at what velocity does one start having problems with lead fouling in a barrel?
Thanx, in advance!

gdub, I don't have any experience with the 475T, but we did run Cast Performance cast gas checked bullets to just short of 2000 fps without any leading problems. Give Grizzly Cartridge a call. I bet Mike or one of them can help you out.

10/4

Can Do!

Will Do!

Thanks a bunch!

ya!

Nice pick up.

A lot of 475 cal cast bullets are likely designed for pistols, ie they may not be gas checked and are designed for lower velocities / pressure. Before loading a heap of them check they fit the throat and, when loaded in the case, they feed and cycle properly.

I have used cast bullets in a 475 Turnbull,have also used them in other big bore rifles,all the bullets were gas checked,no leading issues at all at max speeds,it's been awhile,I am going to PM you with a load direct from Doug Turnbull.

Got your PM, and replied.

Appreciate you taking the time to do that.

Best,

GWB
