I told you these were 358156 and that I loaded them w/o GC.

THEY TUMBLED! No ****! At 7 yards, 2 out of 6 tumbled.

This was in my 3" 65-5.

I tried them in a 4" 586-1 and a 5" 27-0 and they shot fine.

They went where I pointed the barrel, but they tumbled, so these are a no-go for the 65-5. I expect the extra barrel length made the difference with the other two revolvers and this gives me hope of the 4" 13-3 I'll be trying them in next week.

The best news is that I shot near 100 full power 160g cast (358156 wGC) over 15.5g W296 and it ate 'em up! One big hole at 7 & 10 yards.

I also used a magnum case and 5g W231 under the same bullet w/o GC and they shot just fine. No tumbling, no issue, accurate as sin.

So, souping up these bullets and not using the GC doesn't work in my 3" 65. I bet if I used the GC they'd work, so further experiments to follow.
