Philinms, the RE25 should be way to slow a powder for the 140 wt. bullet. The slow powders work good with the heavier bullets. I have some IMR5010 that will not shoot 140s in my STW but the 160s and 175s just lust for this slow powder.
I'm thinking you meant H5010?? Re 25 and h 5010 are way apart for burn rates. When re 25 first came out alot of people thought it had a burn rate between 7828 and h 1000. At first people seemed to recomend loads more towards h1000 but the burning speed now seems much closer to 7828. I checked with quickload and it liked about 79 grains of re 25 under the 140 and about 75.5 under the 160. Both these are 2 grains over what it thinks you should burn of 7828.
My theory--be it wrong or right is that I would consider the strongest load of 7828 as a starting point for re 25 and work up from there. OR better yet go to alliantpowder.com and check their loads.
