[QUOTE="budlight, post: 1017524, member: 2939"] I don't know anything about the new imr or 780, But over the years I also worked up my hot weather 7828 and the SSC to acceptable case life and pressure. I just wrote Summer time on the 50 round cases. For sub 45 degree hunting I had worked up a load with @ 1-1.5 more grains of powder and chronoed them at the same speed and impact point. Then as new slower powders showed up I tried them. These long bullets kind of limit you to @ 58 grains in a 270 Winchester case. Other cases like RPeters are like a grain or two less in volume. Since you have a short throat, I would consider renting a 270 AI reamer which adds about 6-7 grains of case volume. Wildcat went out of business years ago and I ran out of 169.5's and I kind of gave up on F1 class shooting. I zeroed in on 150 BT's and they are a real game getter pushed at higher speeds. Then Matrix bullets open up and I just never got back into the .277 cal. I went to 243 win to have fun with [/QUOTE]
