JJ I got kind of lost here on what we were discussing. RL33 works well for me particularly with the heavier bullets. H1000 just works period. It's the one powder I can always seem to get a good shooting load with no matter what.
Ahh, well I do tend to get confused, that's why I always do the quote thing, it helps me keep things straight.You advised me to try the 175 accubonds ,since I've no RL/26 Or Vit570, maybe RL/33 would work cause it works for you , I see it about but never thought about it in the STW , thks n Cheers
If you ask nicely someone will run it on quickload and give you some starting references. If you have a 9 twist you should have no problem stabilizing the 175's.You advised me to try the 175 accubonds ,since I've no RL/26 Or Vit570, maybe RL/33 would work cause it works for you , I see it about but never thought about it in the STW , thks n Cheers
Go to the main reloading forum and ask, this is kind of our private STW spot.
Cheers
What bullets do you have available?I don't have the 175 accubonds but that's ok ,and I don't have the RL/26 and Vit 570 Or RL33 but it's all good. My twist is 1/9.25 which probably won't stabilize them any way ,but thks I do have H1000 which is a great powder ,and thks WildRose and the STW brotherhood for the great info
You could be right, and I agree partially but not completely. The LRM is a little over 1/4" shorter. Thats very substantial. I wouldnt consider shortening that much, not even half that much, would make a difference, and with 40° should would make up most of that lost capacity and get more of a 195 out of the powder column. It would only be to run 195's. Taking a little taper out would help too, and give a more efficient burn. I couldnt imagine that LRM has near the case capacity as STW. LRM 30° shoulder is a slight improvement but not much. I think the biggest reason even proprietary cartridges dont do 40° shoulders is reliable dependable feeding, and brass quality limitations. You just cant design hotrods at the factory, that admittedly has some disadvantages, feeding and pressure. Youve gotta hot rod them afterwards. Longer necks and 40° shoulders are a little easier on throats. All that said, you could be right, and its just my opinion based on much less experience than you and others. I still think you could increase performance with 195's. The case design comes up short when you move up to 195's, unless you make a single shot out of it. The Shermans are getting 3200 fps with 175's in a 3.2 coal, maybe 3.3 with no pressure signs, and accuracy. Granted thats ADG brass. You couldnt do it with most brass out there. How does that happen? That matches my 180 loads in my 1/2" longer STW.
I agree, that 375 great things are beginning to happen with. I suspect that one will be wildcatted in all kinds of ways, once quality brass is available. Good luck with it, and Id be interested in knowing how it comes out.
Less volume in the vessel, equal loads, greater pressures I suspect along with slower burning powders specialty than we had when the STW was born.
Well if I had any remaining doubts the 300 PRC proved my theory. The 375-300 was the first thing I thought of literally the first time I saw the proposed drawing of the .375 Ruger. The 6.5LRM just confirmed it for me. If I can pick up four to five gr's in capacity with the shorter neck of the 6.5-300 Ruger I should be able I think to pick up at least another 150-200FPS with the right powder. That would send my 140gr Accbonds down range at a smoking 3500FPS and the 123gr Peregrine VLR4s should be running easily between 3,700-3,900fps which will absolutely smoke coyotes, deer, hogs, antelope on the plains or out across wheatfields.
