The 180gr. Accubonds performed flawlessly from my 300WM on the game I shot with them since the Accubonds come out for the 2004 season. My buddy shot his moose with his 300WM-double lung, small entrance wound, huge exit @ about 150yrds-1 shot kill in 2004 and 2005 season For myself, I shot my NT mulie- 1shot kill dropping in its tracks @ 44m- quartering away, shot behind the LF shoulder , and found the bullet in the RF shoulder hide,as it went thru the RF shoulder. THe bullet weighed 150gr (83% retained) with perfect expansion. An hour later I dropped my 8x7 WT @ 554m-1 shot kill, double lung complete pass thru. Small entrane,huge exit. My pics are posted in the Hunting forum - Big game pics about Pg34-36.
To add a bit more about the Accubonds performance, my wife (then fiance) in 2004 shot her first mulie buck (155-160BC) @ 440 yrds, and her cow elk @ 200 yrds. with a Tikka T3 LS 270WSM using 140gr. Accubonds - All 1 shot kills again. To say the least, I was very proud of her! I also to my cow elk in 2005 with my 270WSM @ about 200 yrds also 1 shot.
I have just reloaded some 200gr. to try out at the range. I can tell you is that your moose this season will be on the ground with the 200gr. for sure!
Good Luck!
