[QUOTE="budlight, post: 2725240, member: 2939"] I have some AI's. I have some limited life barrels. So I fire form with the perfected AI rounds powder levels. They chrono within the ES. I have a 7STW wildcat. So baby 7mm's have never interested me. I'm a lifetime 270 win person and the 270 AI was a natural improvement. .277 we lacking in VLD bullets until Wildcat and Matrix bullets came along. I've perfected the 169.5 and 175 grain bullets. One thing that I have learned from hunting is that High sectional density bullets just punch holes in critters. 270's with 150 - 190 gr just leave the deer standing and you wonder if you somehow missed and then in what seems like an eternity they fall over. tiny hole in and out on your classic broadside heart and lung shots. So on my deer hunting days I use 129,130, 135, 140 grain out of my .277 caliber rifles. I have 26 and 29 inch .277 to get the most velocity out of the slowest powders and still have good case life. Often the most accurate rounds are below max loads. My advice is to use at least 26 inch barrels One of my farvorite .277 with good BC is the Barnes. Pre-season I spend time at the range paper punching out to 600, but it seems like every season the game is relatively close. I have one 428 yard laser verified by friends before shooting and it was a bang flop. 129-grain LRX BT Sectional Density .240 Ballistic Coefficient .463 I acquired a custom 257roberts AI with a 26 inch and it has always been a one shot on deer and antelope. It's near the velocity of 25-06 I don't own a 260 rem. I do have 243's and 308's. 308 AR10's are my pig guns. 243 is varmints and up to antelope. [/QUOTE]
