Hey Veral,
I mentioned that I might post this and got your tacit okie-dokie so here goes...
I got a friend to join me in an experiment recently.
I used a Lee 6-Cavity mold and he used a LBT, 4-Cavity mold and we used the same pot and ladle and each made a pile of bullets until we were scraping the bottom of the big 35# pot.
Not only did he make somewhat more bullets than I did, (because he didn't have any stalled moments in his operation,) nearly all of his were usable bullets while I had many culls (even with our very lenient judging.)
I can't say how many bullets we made cause we had two big piles and didn't feel like counting them.
The difference was easily established in our minds. (Maybe weighing them would really tell the tale. Hmmmm.)
Between ease of operation and better resulting bullets the cheaper model's attraction is rapidly diminished.
We challenge others to give a try at similar tests and see what you get.
Maybe just to see how many bullets they can make an hour with 1-hr devoted to each mold. That would be a tell-all too.
The real spike is when the bullets are sorted.
Big difference!
By the way, we had already noticed an accuracy difference, thus:
All of this is with the Lee C452-300-RF cast bullet vs the LBT 454-300gr WFN-GC with very similar nose lengths and same sizing dies, lube (LBT Blue Soft) etc.
At velocities below 1100-fps there was no important difference for us.
For 45 Colt loads up to about 1200-fps the difference was hard to establish until some distance is added to the situation. At 50 yards the groups began to get wider with the Lee bullets than with the LBT-WFN bullets of same caliber, weight and load, (very similar in appearance too.)
In the 454 revolvers, at higher power (over 1250-fps on up to 1700-fps) the difference is much easier to see.
In all cases targets at 25 yards do not tell you much.
At the 50-yard board is where things start becoming obvious.
Even with our flinching from the higher power we saw a notable difference in the way these bullets printed groups. Lee bullets were almost useless beyond 50 yards. The LBT bullets could be kept on a notebook paper at 100-yds with iron sights and eyes going dim.
In all cases where a difference was plain to see, the Lee bullets made wider groups.
(Some might refer to these groups as "patterns".)
Since our shooting is normally at velocities below 1300-fps (no matter what cartridge & load) we seldom have a problem with either bullet for shooting deer, (for which 1000 to 1200 fps is plenty with 300gr bullets of any type.)
As with anything, the first order of business is to make a good [accurate] shot.
Lots of power doesn't help much when a bad shot is made.
Therefore, we make loads that we can shoot well.
I don't think the deer can tell the difference when a 45+ caliber hole is punched through the heart/lung intersection.
Additional info: All the guns used have been "tweaked" for cast bullet shooting, (4 guns in all.)
Anyone else have similar comparisons?
