240 weatherby vs 243 win ballistics

“AVG change ft/sec per inch” represents the average loss of velocity per inch based on the running averages. Weatherby’s move to Wyoming is an exciting step towards continual opportunity for innovation. The .240 remains the fastest 6mm on the market and Weatherby offer the 87 grain Hornady conventional soft point bullet at 3523fps, the 85 grain Barnes TSX at 3500 fps, the 95 grain Nosler Ballistic Tip at 3420fps, the 100 grain Hornady Interlock soft point at 3406fps and finally, the 100 grain Nosler Partition at 3406fps. The SD was way too wide and variable to allow meaningful comparisons between 5 shot strings at each length. one does not relate to the other outside of they use the same bullet size. Average velocity reduction was 42.3 feet/second per inch of barrel length. The 257 isn't even in the same ball park. Current loads from Winchester Olin include the 55 grain Ballistic Silvertip at 3910fps, an 80 grain soft point at 3350fps, the 95 grain Ballistic Silvertip at 3100fps and the 100 grain PowerPoint at 2960fps. by Philip Massaro - All else being equal, the 240 Wby should get 150 - 200 fps more than the 6mm or 243 win. In this post, a continuation of Rifleshooter.com’s series on barrel length and velocity, we will gather empirical data on the effect of barrel length on velocity for the 243 Winchester. The 6mm Creedmoor came to light as a wildcat, but not in the traditional way. Weatherby Mark V Ultralight .243 Win 24" SS Fluted Barrel This rifle is used and shows some handling around the pistol grip and the forearm.

It uses a shorter case than the .243 Winchester—1.920-inch vs. 2.045 inches—allowing for a longer bullet length outside the case in the same length magazine, and maintains the 6.5 Creedmoor’s 30-degree shoulder. If you want a 6mm rifle that will serve you both in the deer stand and for precision shooting, perhaps the 6mm Creedmoor is for you after all; the factory loading are increasing each year—you’ll find loads from Hornady, Federal, Barnes, Remington and even the new Sierra loaded ammunition—and I think availability and selection won’t be an issue. Remington dubbed theirs the .244 Rem., while Winchester went with .243 Win. Long range meduim game thumper. They also bled velocity at a lower rate than the .243 Win though we also noted that the sub-60grain .243 Win rounds had a hand it that distinction. has largely enjoyed being the king of 6mm mountain. by 300 fps. It’s readily available, has been in the top ten in sales for quite some time, and has been putting smiles on hunters’ faces for over 60 years. was designed for. I knew that our 300 Winchester Magnum: How Does Barrel Length Change Velocity- A 16″ 300 Win Mag? Does a Ferrari compete with a Yugo? “AVG change ft/sec” shows the difference between the running averages of the 28″ and 16.5″ barrels. Post was not sent - check your email addresses! The 6mm Creedmoor would come along—almost as a fluke—in 2007, and follow the short case/long bullet trend in cartridge development, but does it have enough to make a hunter deviate from the tried-and-true .243? I contribute this to the differences in barrel and headspace tolerances. is an apples/oranges comparison i.e. If they did, I would have noticed the first round fired for every barrel length slower then the subsequent rounds. Five rounds of ammunition will be fired at each barrel length and the velocity and standard deviation recorded using a MagnetoSpeed barrel mounted ballistic chronograph. It works great with the 243 Winchester. outclassed the 6 mm Remington and the newer.243 WSSM by about 150 ft/s (46 m/s). And he would have had more measurement precision firing 10 shot strings and cutting off two inches at a time”. This provides data for barrels 24, 22, 20, 18, and 16″ long. Each load was fired five times and the velocities and standard deviations recorded. That’s a case capacity difference of 20.07% favoring the .25-06 Remington. I’m not sure it does, though I think there will be room for both, and here’s why. If you’re the hunter who likes obscure cartridges, the .240 Wby.
