[QUOTE="winmag, post: 383817, member: 22166"] I origionaly went with 150gr SST's in my 270wsm, due to the high B.C., and same load data as IB's.(I couldnt find IB's anywhere). I worked up a load for them, 61gr IMR 4831, and they shot beautifully........ but when I shot 450 yds I recovered 2 of 24 bullets fired, and both had complete core/jacket seperation. Very unhappy so I swiched to 140gr accubonds, worked up a load, 64gr of RL-19 and shot 500 yds and recovered and weighed 5 mushroomed bullets. avg wt retained was 101.6 gr. Happy now. **this was not a bullet test, I shot targets, and recovered bullets out of the dirt** But my velocity at 500 yds was (on paper anyway) 1428fps. I have no real data proving that speed, as I have no chronny, so my aprx speed was from the chart, and load data for the 140gr Accubonds. Im happy now, but if I swich back to Hordady, I will shoot thier Bonded (IB) bullets or non bonded BTSP's. So I know what to expect for performance bonded or non bonded. Based on the game I hunt, and the yardage I usually see and shoot them, (600yds and less) I prefer a bonded bullet. If I were to strech the legs on my yardage a bit, Id consider the SST again. They do shoot beautifully! I noticed Hornady offers SST's in thier Superformance ammo, but dont offer them in the WSM's.........Maybe its just my caliber choice???.......... [/QUOTE]
