So here it is in a nutshell. I have been shooting the older Federal load which uses the 150gr Solid Base at around 3250'ish fps. I haven't bothered with loading for this thing since the Fed fodder shoots so darned well. That said, I have just about any powder I could want to choose from beginning with RL-22 on through the main stream factory stuff into 860, and 872. My initial plans were to load up and run some 160'ish grain bullets in the STW and concentrate on the 139'ish bullets in the 7 RM. I haven't gotten to either one yet. So not knowing how many rounds the older Rem Senadero had through it before I picked her up second hand, and knowing I have close to 200 rounds of the factory stuff through it now, which powder would you start with, if you were going for the shortest work up to find a good shooting load? I'm not looking to break any speed records just looking for a great shooting stable load. As for primers, and brass, I'm set with all the Fed GM 215M's I can handle. It is my preferred primer for anything going over 70grs of powder. Brass I have in both once fired Federal form the factory stuff, plenty, and a few hundred each in Rem and Winchester brand new still in the bags. The main bullet I have on hand for it is the Hornady 162gr SPBT and several hundred of a "VERY SIMILAR to Hornady" 162gr Plastic Tipped Bonded Core Blem. I figured either one would work just fine on the deer and hogs I play around after, and for the most part anything else I set them to task on for that matter. I have plenty others all lighter however that I can use but would like to stick with this one for the STW. Anyway throw a fellow a bone here, I read through most of the post in the loading thread below, and like I mention have H-1000, RL-25 and others in enough quantity to burn out the remainder of this barrel and most of another one. Give me your best thoughts on where to start. I'm not a real fan of 25 since here we get some pretty big temp swings and I have found that it gets a bit touchy when worked up in mid ranged temps and then touched off when it's a bit hotter. Don't forget I am also down here in real atmosphere, that actually has water in it, sometimes almost thick enough to see. It can and does have an influence on powder charges as we found out when working up the 270 AM. Anyway throw something out there and I will give it a try. Hopefully this weekend even with the heat we're supposed to have I am going to try and get out to shoot.
