I enjoy shooting a Friendswood 148 DEWC out of my 642. Set it in front of 3.4 231 and it is fun to shoot a few cylinders.
When I put the megalithic blasters in I wear a golf glove.
I don't shoot a lot of those it's just stupid to me to punch paper or rattle a little steel with those at their cost.
Nothing wrong with a 158 LSWC sittin on 4.0 to 4.2 231 either.
I have a 640 that should be here sometime soon I'm kinda interested on how that's going to feel in comparison to the 642.
Megablasters in that may not be a bundle of joy either, but for sure they will do what they are intended. Some stout .38 may be fun.
