I really have not taken the approapriate time and space to explain my why for the 25-300WBY. Now I know there are a lot of opinions and theroies out there and I am not saying this is the best of anything. It is just something I really wanted to try and was encouraged by some of my friends to do so. Now to begin with as of late my favorite rifle and cartridge has become my 416WBY Mark V shooting a 350gr TSX on the average of 2930fps and it shooting at 100yds consistently .496"MOA.
Let me begin by saying that Roy Weatherby did not have three things in his day of developing his fast cartridges that we now have in our day. Yes, Roy was hampered by three things, 1. First, needing slower burning powders that we today have in many forms. 2. Second, needing good tough bullets that would hold together up close and still open up way down range like the TSX. 3. Third, needing the steel we have today for making our barrels that last longer.
I believe if he had these three things I mentioned in his day we would not have the 257WBY Mag but would have had the 257-300WBY mag and the 270-300WBY mag and the 30-378 would have been in production a lot sooner than it was.
Well, I might get run out of town for this but with the tough TSX I plan on hunting everything but the big brown bears. Hoping to get somewhere between 4100-4200fps with 100gr TSX, 3823ft pounds at muzzle and still retain 1536ft pounds at 600. I would sight in at 2.9" high at 100 and my zero would be 415yds and only -6.53" at 500yds. Yes, I can hear it coming but with 3800 plus pounds of energy and a tough bullet just about anything I want to shoot it will kill and the hydrostatic shock will be phenomenal. The hydrostatic shock will be so great in it's hydraulic force that it will cause the blood to flow backwards and stop the heart if the heart is not what I actually hit. It will devastate what it hits and if this really works out it will be a for real one shot killer. With my calculations of hydrostatic shock at these velocities producing such a great hydraulic force the bullet could be placed anywhere in the main part of the body of the animal and still kill him quickly. Of course my 25-300 will have to share time killing game with one of my now favorite rifles which is my 416WBY and I just love it. Ok, I am ready for all the opinions, and don't we all have some.
I am nervous, I sure want this all to work good because that would mean no more BDC scopes out to 600. At 540 yards hold on top of shoulder and good to 620yds. I do have to account for wind drift and wind can really mess up long shots and even practice doesn't make any difference some times. Of course I am only interested in being able to rest my rifle and make shots out to 500yds and not have to worry about bullet drop. And for deer size game and up this should be the ticket. I sure hope so and as I said I am nervous but also excited. I know a lot of you guys know exactly what I am talking about when I say nervous and excited at the same time. But I was willing to take the risk and have an open mind enough to try this thing. Hope I am this open minded after I develop loads and shoot it. This is just a post to kinda explain my thinking and it sure is not perfect but this is where I am as I try this cartridge and we sure will see when the rubber meets the road in a about three weeks.
