One mould I have used a bit with 32 H&R and 327 Federal is Lyman #313631. I think its nomenclature was meant to correspond to the nice little S&W Model 631 Kit Guns made in 32 Magnum in the late 1980s and into the early 1990s. It would not hurt my feelings one bit to run across one of these at a fair price. The bullet is a 100 grain SWC with a small meplat and gas check base. Gas checks seem kinda costly/decadent and superfluous with the fine RCBS 32-98-SWC that shoots so well at varying velocities, but what the heck--the mould was reasonably-priced.
The bullet's initial test drives were not promising--sized @ .314" for the throats, velocities of 900 FPS produced mediocre accuracy, using the same powder/weight that shot so well with the RCBS. GMBTA. I continued with stair-stepped loads with the WW-231 that the Manual stated should produce 1000--1100--and 1200 FPS. The short version--the faster I ran these Lymans, the more accurately they grouped at 25 yards. GMBTA. again.
One of those quirks of the combination that I filed in the back of my mind--The Lymans Like It Warmed Up Some--in the 16-4 x 6", at least.
A number of years go by, and the SP-101 joins the herd. The RCBS bullet behaves as well as it has in every other 32 caliber wheelgun and rifle I have run it in--delightfully. I put together 100 rounds of stepped loads in the 327 brass with the Lyman bullet. I was in terra incognita with the 327 at that time, but I just did "32 H&R + 15%" with Herco to see what would happen. I actually guessed it pretty closely, and the first 25 rounds ran about 1050 FPS and grouped pretty well. 25 each at 1125 FPS, 1225 FPS and 1300 FPS followed, and the accuracy was decent regardless of velocity--as long as it ran pretty fast. So this bullet trait "held" in a second gun by a different maker. And were those high-order loads ever LOUD.
What's it all mean? I dunno, apart from the bullet behaves better going faster. When I stop and ponder that 100 30 caliber gas checks for Lymans #313631 or #311316 run close to $4 these days, I momentarily bate my breath--but soon recall that I am no longer living on Top Ramen and iced tea 4 days before pay day, and my pulse rate lowers a bit. Thrift is a hard reflex to overcome.
For my uses in a 32 revolver, one of the post-war S&W Models 30 or 31 x 4" would be just as useful as the SP-101. The postwar models can manage loads running 100 grainers at 900-950 FPS without strain or decreased service life. This will likely be my load range for the 32 H&R and the 327, so the Lyman bullet will get relegated to July 4 celebrations in the desert or attempts to set off earthquakes in fault zones. There might be a time and a place for 1400 FPS loads from 30 and 32 revolvers, but small game and small varmints don't need all of that fuss, bother, and eardrum drilling.
