[QUOTE="Lefty7mmstw, post: 751553, member: 48043"] I can't help much on the varmint loads for your 270 but I'll say that imr 4831 and rl22 are two of your better choices for 130 grain bullets with rl17 and the 4350's doing very well also. If you step up to 150's I'd try i 7828 first. As far as interchanging powders of the same number from different manufacturers, use data for the correct brand. Watch the brass brand and primer choice for the load also. It means less here than with shotgun loading but if you have only magnum primers and the load calls for standard you'll have to drop back a bit more on powder charge to start with; and if they want mag. primers and you only have standard you may not want to load that combo as the primers you have may not light it up sufficiently for good uniformity, especially in cold weather. The 4831's are particularly bad for difference as imr 4831 is [B][I]a[/I][/B] [B][I]lot faster[/I][/B] than h4831 and you could damage your rifle subbing imr in for an h4831 load. The 4350's and 4895's are closer but they are sourced from different powder manufacturers so the data will vary. As you progress in the hobby you will see the forest from the trees better but stay with known data to start with and don't try off the wall stuff. I've been loading for twenty years and loaded for 50 + rifles and there's still a pretty good pucker factor when pulling the trigger the first time on a load with little or no data like a new powder or mil-surplus stuff. It's hard to stock up when the shelves are already bare, but you should settle on a load and get a year or two's supply of everything on hand. You'll ride out the bumps in the road better knowing you HAVE the stuff. [/QUOTE]
