[QUOTE="dchamp, post: 678110, member: 51652"] Hi Vin, I don't know much about the 270wsm but VVN570 works real well in my 7STW and 160gr Accubonds. I looked your choices up in Quick Load and it doesn't look like you have enough case capacity to do any good with that powder. The program could be wrong but thats it's indication. According to the program a better choice would be VVN 560, Alliant RL-22, MRP, Ramshot Magnum, IMR7828ssc. It shows charges in the mid 60gr range up to 70gr's for the slower powders. All powders listed show 98-100% propelent burnt in a 24" barrel and 3000 -3100+ fps MV. Like I said I like and use VVN-570 in my 7STW but I'm using 80gr's+ and it's a pretty slow powder. Don't know for sure but I hope this helps. GOOD LUCK!!!:) [/QUOTE]
