Avoiding a gas check reduces the cost of a bullet by half. Dam gas checks are 5 cents each. In earlier days I might have jumped as I have looked at that bullet many times. My 180 is a gc design and I won't be buying any more.The 38/357 bullet with two crimp grooves is the Ray Thompson designed Lyman #358156
a 155 gr. SWC with a gas check .
Back in the mid 1960's when I started reloading ... 38 special cases littered the public range floor , free for the sweeping up . 357 Magnum cases were few and far between , Using 38 special brass you could seat the bullet in the lower crimp groove and have about the same case capacity and length of a 357 magnum round to shoot in your 357 magnum revolver. It was prudent to avoid Maximum Loads but mid-range loads worked fine .
For loading 38 special you seated the bullet to the upper crimp groove in 38 special brass .
These worked fine in a S&W model 64 38 Special and a Ruger Blackhawk (three screw) 357 magnum ... those are the only 38 / 357 handguns I own , but no problems chambering the loaded ammo .
That design still is a good bullet for 38 spcl / 357 magnum .
