Anyone out there have any load data for the old Winchester 351 Self Loader using 180 grain bullets? This is for the 1907 model semi-automatic. Thanks for any and all info.

You could try 19 grains of 2400 or 20 grains of IMR4227.

Bill - I don't shoot a 351 but I have a buddy that does. Him and a buddy of his have what they call their secret load. It's not secret anymore because here it is. 15-17 grains of IMR SR4759. He said to start at 15 and work up.

Well thank you Gentlemen for your swift response, I figured there would be someone who would have some ideas out there. I have had the rifle for a while now and have wanted to try it but, did not want to have to use the old cartridges that I got with the rifle as the boxes are very old and are probably collector items. Much appreciate the feedback. Will have to get around to loading up some old brass I have with my lee load all dies.
