Thanks to Michael I am going to try a cartridge that has really got me excited. I am sending my 257WBY him and he is going to ream it to a 257-300WBY and I will be fitting it with a HS-Precision stock. Michael says, that all I would need to do is a rechamber job and nothing else changes besides the metal mag well will need to have the reducer taken out which is just removed very easily. My cases will be formed from .300WBY in .270 dies then to .257 dies with out the decaper and expander, then neck reamed for the first run cases only. Then I can use the .257 dies to form, neck size, and reload it like I always do. As Michael said, "I can tell you that John Lazzeroni has nothing on this round." It will move 100gr TSX at 4060fps plus, has 3660 pounds of energy at muzzle and still has 1464 pounds of energy at 600yds. Sight in at 2.9" high at 100yds and only be -8.1 at 500yds. I will not get it back until sometime in October or November. So it will be for later this season at best. This will give me cool months to develope a good fast hunting load with the 100gr TSX. As I said, I have been ask to right a review on it once I get it. Reporting on load development and accuracy as well as killing effect on game. If the rifle barrel is not free-bored the throat would might not last a 1000 rounds but being free-bored (as some have already discovered with free bored barrels they last longer) so I am guessing it will last somewhere between 1500-2000 rounds. Also when at the range I will not shoot it hot allowing it to cool completely between rounds. In doing so it will insure a longer life for the barrel. Of course this is not for varmints so I won't fire many rounds, the most being from load development. Yep, this ought to be cool and just fun to try. With my 257WBY reamed to 257-300WBY and with the 100gr TSX, I am sure I will be in awe of this cartridge when it hits game whether up close or far off. I bet it will give me the preception (not accually happening) that before the recoil moves the scope you will see the animal being hit even at long ranges." Yes, this will be a lot of fun when the rifle is delivered and I begin to develop loads and go shooting.
I just love this stuff, it is so much fun. I love very well made rifles, fast cartridges and hard hitting tough bullets. They create the best of all that man has tried to accomplish with the hunting rifle for killing game. First, speed, causing hydrostatic shock due to high energy that tears stuff up. Second, penetrating momentum from velocity times mass which makes deep holes that let air in an blood out. Third, devastating everything around and along the wound channel upsetting the skeletal and nervous system along the way, insured by tough bullets like the TSX opening up and holding together. Yes, this should be a lot of fun.
