Lee REAL 54cal 300gr

Was wondering if anybody knows where I can get a mold or 2-3doz of these bullets? Doing a bear hunt this year, and I've heard they shoot decent in slow twist roundball 54cal barrels? I'd be more than willing to pay appropriately if someone would do me a favour? My gun is sighted in with roundball with a 75yd zero and it's 2" high or so at 50yds. Figure the difference in velocity will be negligible at the 25-35yds I'll have over bait? Appreciate any help. PM me and we can go from there...

Just sharing my personal experience and info from local friends.
The Lee REAL is notoriously small for factory bore rifles in all sizes. Rifling Engaged At Loading does happen,, but it's usually with just the bottom band and they don't do very well with filling the entire bore for gas sealing. Extra work with paper patching and a good over powder wad or other seal helps a lot.
I hope someone steps up to find you some to experiment with (get both sizes if possible).

The Hornady Great Plains bullet is another one to try and (personal opinion) is hands down better for an over the counter available bullet

I have a mold for of the 380gr variety and my experience has been exactly as described by @necchi. Too small for the bore of my Cabela's rifle. I experimented some but decided to just use PRBs instead. I've also used the Hornady Great Plains bullet, but believe they've been discontinued recently. Lyman makes a similar and popular mold though.

Just use a prb for the bear hunt. You’re talking 25yds. It wont fail ya!

Thanks guys. Like I stated in an earlier thread I'm just a lil concerned about an extremely large bear and blood trailing. I've shot alot of deer with prb and I haven't gotten an exit wound on anything inside of 50yds. My assumed cause for this is the extreme velocity with me using 100gr ffg T7 and immediate expansion? Still they drop within sight everytime so blood trailing isn't necessary.

The .50 cal REALs I have cast (of the few I’ve measured) seemed to drop at about 0.517” and my Lyman groove diameter is said to be about 0.520”. Having heard conicals often need a felt was I punched some prior to trying a few, but tried one as is. At 50 yds it keyholed and was about a foot left and several inches low. The next two with a wad were nearly touching and just under the bull. This is with a 1:48” twist and the heavier 320 grn version.

I have since tried some more and varied my charge (had used my typical 70 grn charge that I used with PRB just breaking in my rifle using Pyrodex) 10 grns at a time from 60-100 and nothing shot well. Using Olde E. I’ve certainly got a lot of work to do, but I feel it should eventually do well.

I cast a 38o grain real in my CVA hawken over 90 grains of RS I shot a cow elk at 45 yards drop her in her tracks!
