I think, having seen the "bobbly" appearance of the
bases of fired bullets with some "hot" loads, the
"melting" might better be ascribed to ablation of
the base by the explosively heated gases, as more or
less suggested by Steve in an earlier response.
With non jacketed bullets, this would result in a small
build up of vapourised lead condensing in the barrel
behind the bullet. Lead to lead has an extremely high
friction coefficient, so successive bullets would smear
more lead on to the fine layer present from the first
shot, leading to the usual array of interesting effects
seen with fouling. This effect will be mitigated somewhat
by the efficiency of the lubricant used. This should not
be taken as the sole cause of fouling!
Open base FMJ will be affected rather less, the lead
alloy being somewhat confined by the ring of the jacket,
and obviously not having the lead-to-lead friction aspect.
A fully cupped jacketed or gas checked round will not
see this problem at all.
With baked Alaska, I think the meringue will tend to
build up as a sticky fouling in the rifling, causing
the meringue/cake jacket to strip, and unless the
icecream is deep-frozen, it will distort and accuracy
will be lost.... <G>
