That 240gr in .452 is dang short...I know some that do use the 250gr in .452...

The 240gr XTP in .429 has been used since the beginning of the inlines and has done very well...The reason I went to the .429 in 300 gr is because of the great ballistic coefficient...It's very close to the 250gr SST which I used for a few years...I wanted that higher coefficient for hunting over our soybean fields down east but also wanted to move to a hollow point design to help the bullet open up...At the lower powder charges my gun likes the SST didn't expand well on lung shots...

Now...The .452 300gr XTP also has a great following..One is a fellow up the road in Greensboro...This is the guy that invented the smokeless design that Savage picked up...It's his bullet of choice and he tests it in eastern NC and makes shots over 200 yards with it...Even at higher velocities he still prefers this bullet over the Mag version...

Any of these 3 (4 if you count the .425 250gr) will do a good job...The .429s are just a bit more streamlined and in my case my rifle groups the .429 300gr best...That's another reason I use it...
