Since load data for the .351 is so scarce, I thought I would put this out there for others.....
I got this info from Handloader magazine #300, which has a nice article about Winchester's forgotten M1907 .351WSL.
166gr Accurate Mold 35-175AG RN/FP - Unique 10.0gr 1,677fps - 64 -spotty function
......................."............................. AA5744 17.0gr 1,680fps - 28 - most acc.
......................"............................. IMR4227 17.0gr 1,658fps - 23 - med. acc.
181gr FMJ (unknown maker) - AA5744 17.0gr 1,589fps - 47 - very poor groups
.....................".................. IMR4227 17.0gr 1,563fps - 84 -
181gr Buffalo Arms Plated RN - Unique 10.0gr 1,547fps - 38 - mediocre accuracy
...................."................... AA5744 17.0gr 1.535fps - 49
...................."................... AA5744 18.0gr 1.624fps - 97
...................."................... IMR4227 17.0gr 1.569fps - 34
....................."................... IMR4227 18.0gr 1,593fps - 58
180gr JSP Rem-UMC factory load ......................1.897fps - 71 - several dead primers
180gr JSP Peters factory load.............................1,906fps - 174 - very erratic vels.
Note: All 100yd groups were 5 shots ea. All handloads used Caplock brass and Rem 7 1/2 small rifle primers. Cast bullets were poured of straight Linotype, sized .352 inch, lubed with SPG and fitted with 35cal Hornady gas checks. Mold is two cavity steel.
My mold is very simular to this, ordered from Tom at Accurate, only mine is 180gr (35-180CG) with tumble lube design. It is three cavity aluminum, still waiting for it to arrive.
