any of you guys have one, ive been really looking hard at one, I just think its kinda cool round, plus I have a bunch of .257 bullets! any pros and cons? is it a barrel burner?
Your comparing apples and oranges. But if you do want to compare, the 257wby has over 150 more ft lbs of energy compared to the 7-08 at 400yds. The 257wby also has over 14" less drop at the same distance. The 257wby does it with about 1/3 more powder not twice as much, which comes to around $.10 worth of powder per case or $2.00 per box of reloaded ammo.grovey said:Flat shooting is all it has going for it in my book. The lil 7mm-08 leaving @ 2650 with a 162 amax has as much energy at 400 yds as that big belted flat shooting magnum leaving at 3500fps with it's 115 gr pill. The 7mm-08 does that with half the powder too.
14"+ at 400 yds, The 257wby easily only drops 1/2 of what that 162gr 7-08 does between the muzzle and 300+ yards. 120gr bullet's are available in the 257" and 7mm, and would make more sense to compare the two with equal bullet weights instead of a 162gr 7mm vs a 115gr .257.Asajoe1 said:I'm too lazy to look it up, what is the difference in drop at 400 yards between the 2 and 115 g. isn't the only bullet to choose from is it?
I agree, those would be better comparisions. I had a couple of 25/06 Rem. rifles over the years. I bought the 257 Weatherby because it was faster and more powerful, less efficent, yes but I was willing to burn more powder even if the cartridge was overbored and not as efficent. As another example, I own a 2003 Ford Mustang GT Convertible in near mint condition. Is it efficent on gas? No not with that big 4.6 L High Performance V8. I am willing to get less gas mileage for more performance. If I want efficent I drive my Jeep Compass 4 cyl. The Mustang like the 257 is cool. The Compass like the 7mm/08 is efficient.Ken S. said:In terms of comparing different chamberings, wouldn't it be more adequate to compare cases with the same projectile and similar case capacities? For example,
I feel the 7mm-08 is in a completely different class than the 257Wby Making a comparison completely one sided favoring the Weatherby over the 7mm-08.
Being I own both a 7mmRM and a 280Rem, there isn't much difference in performance. A mere +/- 150fps favors the 7mmRM in the 150gr class projectiles. In terms of powder consumption, the 280Rem can be loaded with much less powder to achieve a close ballistic performance to the 7mmRM.
What makes a 100gr to 120gr bullet a "con"? Your example used a 162gr bullet that hit with less energy and dropped like a rock.grovey said:OP asked for pros and cons. The lightweight bullets are a con, and my example shows it. I don't really care if you don't like it. Make a good groundhog gun... grin
