300 short mag ballistics
The situation with rifles in is pretty similar. It has a range of bullet weights from 125 to 200 grains though most would agree that the 150-180 gr bullets often work the best with the cartridge. Additionally, the Winchester Short Magnum Cartridges all have a case with very minimal taper and a 35 degree shoulder.
However, the 270 WSM uses a heavier rifle and the .270 Winchester gets a slight edge when both are used in the same weight rifle. Military and law enforcement departments adopted the cartridge for long range sniping and marksmanship.
Book an incredible Africa hunting safari here. In 1958 Winchester introduced three cartridges – the .264 Winchester Magnum, .338 Winchester Magnum and the .458 Winchester Magnum, all based on the shortened and blown out .375 H&H Magnum case. There is a lot of debate out there as to how we can accurately estimate the stopping power of a round. Ok let’s give them the benefit of the doubt and say they like availability and reliable feeding. Case capacities and reloading data were obtained from Chuck Hawks and Nosler (here, here, here, here, here, here, here, and here). Is it significantly more accurate than the 7mm Remington Magnum? All four loads used a 200 yard zero.Just like you’d expect, there is virtually no difference between the trajectory of each cartridge.
The Chattanooga Police Department[24] and Minot Police Department S.W.A.T units[25] and the L.A. County Sheriffs Department's Special Enforcement Bureau[26] which have adopted the .300 Winchester Magnum in some capacity.
270 vs 308 WIN: WHICH ONE SHOULD YOU HUNT WITH? As you can see, even with the increase in sample size, the general trend we saw in the small sample size remains the same in regards to how close these two cartridges are in bullet velocity. Factory loaded ammunition can be found from Olin (Winchester) starting at 150 grain on up to 180 Velocity is also important when it comes to stopping power. One way to determine the amount of penetration two cartridges will have is to compare the sectional density (SD) of the bullets used. However, don’t underestimate the importance of the greater variety, wider availability, and lower overall cost of .270 Winchester rifles and ammunition.
Does the difference between the two cartridges in terms of accuracy make a difference for most hunters under typical conditions? Many of the most popular centerfire rifle cartridges in the United States, like the .270 Winchester and .30-06 Springfield (both of which have an overall length 3.34″), require the use of what is commonly referred to as a “standard action” or “long-action” rifle.
Both cartridges normally use bullets in 150-230 grain range. Additionally, the .300 Winchester Magnum is a traditional belted magnum while the 300 WSM has a rebated rim and no belt.Just like with the 7mm WSM vs 7mm Rem Mag, even though the 300 WSM uses a case with a larger diameter, the .300 Win Mag also uses a relatively large diameter case itself and is significantly longer. The popular .30 caliber's omission from that lineup was not missed.
The 200 yard figures are 2834 fps and 2676 … Though, we do see a little bit more of a distinction between the averages of the two cartridges. 300 Winchester Short Magnum 190 Grain Information | Ballistics. And because we realize that this is a small sample size, we have compiled the numbers for fifteen extra rounds for each cartridge giving us a total of 40 rounds. Let’s take a look at our ten rounds and see how they compare. While rifles like the Winchester Model 70 were produced in that chambering for several years, I’m not aware of any rifles currently manufactured in 7mm WSM. The maximum point blank range for the 12 g (180 gr) bullet is 300 yards when zeroed at 232 metres (254 yd). https://en.wikipedia.org/w/index.php?title=.300_Winchester_Short_Magnum&oldid=979070946, Articles needing additional references from January 2013, All articles needing additional references, Creative Commons Attribution-ShareAlike License, 165 gr (10.69 g) Full Metal Jacket(FMJ): 3,223 ft/s (982 m/s) (), 180 gr (11.66 g) Full Metal Jacket(FMJ): 3,095 ft/s (943 m/s), This page was last edited on 18 September 2020, at 16:18. Is this difference significant in the relation of cartridge to cartridge comparison?
The sectional density alone does not indicate penetration. Basically, their stated goal was to give shooters and hunters all the benefits of a short action cartridge (like the .308 Winchester pictured below) with essentially the same external ballistics as comparable standard length cartridges (like the .270 Winchester cartridge in the photo below).So, how’d they do it? Both of these cartridges were designed to be able to reach out at far distances and be able to still carry enough kinetic energy and punching power to kill the target on impact and large targets at that. On impact, this kinetic energy is transferred to the target where it causes damage to surrounding tissue and organs.
Second, both cartridges use the same .277″ diameter bullets. [citation needed] However, bullets weighing between 7.1–16.2 g (110–250 gr) are available to the reloader for the .300 Winchester Magnum.
The .300 Win Mag rounds have an average of 80.0lb/f.s while the .300 Win Mag has an average of 77.12lb/f.s. The amount of recoil the cartridge generates is a step up from the non-magnum .30 caliber (7.62 mm) cartridges. The case volume will vary from manufacturer to manufacturer to such a degree the reloading software suite QuickLOAD provides five differing cartridge case capacities, that for reloading purposes significantly differ between manufacturers. Hunters who look hard enough can probably find what they need, but it can be challenging sometimes. From this data set, the .300 Win Mag still has a slightly higher sectional density than the .300 WSM rounds. The 270 WSM does indeed have a flatter trajectory and more resistance to wind drift than the .270 Winchester.
Both of these cartridges take a 30 cal bullet (.308”) but that’s about where the similarities between these two cartridges end.
The short neck was thought to hinder accuracy because it would prevent the alignment of cartridge to the bore, but this is rarely an issue either today or when the cartridge was designed. In that same vein, those fat, stubby 7mm WSM cartridges with their very steep shoulder angle can sometimes present feeding problems. The .300 WSM has grown in popularity since its introduction and of the many recent creations, this cartridge has most definitely proven to be a success.
Both cartridges are also well suited for hand loaders and reloading components for the 7mm Remington Magnum and 7mm Winchester Short Magnum are widely available. According to the U.S. Navy this ammunition should increase the maximum effective range of .300 Winchester Magnum sniper rifle systems to 1,500 yards (1,370 m), decrease wind deflection on bullets in flight and use Hodgdon H1000, a reduced muzzle flash propellant that remains temperature stable across an operational temperature range of −25 °F to +165 °F (−32 °C to 74 °C). The particular 300 WSM load above shoots the same weight bullet at very nearly the same muzzle velocity (over 99% as fast), but uses about 8.5% less powder. The first three cartridges were all designed and marketed specifically as short action alternatives to extremely popular and effective standard length cartridges: the .270 Winchester for the .270 Winchester Short Magnum, the 7mm Remington Magnum for the 7mm Winchester Short Magnum, and the .300 Winchester Magnum for the 300 Winchester Short Magnum. From this data, either of these cartridges are going to provide options for flat shooting rounds and probably isn’t the category you will need to focus on until you start trying to decide which round you are actually going to cycle through your rifle. Remington 88.0 grains of H2O (5.70 ml) Depending on the cartridge and grain size the .300 WSM can
For the .300 Win Mag, the Hornady Superformance SST 180gr stands out to us as an excellent round to bring to the range. This is an incredibly small practical difference. .300 Win Mag Federal Vital-Shok Trophy Bonded 180gr, 300 Win Mag Federal MatchKing BTHP Gold Medal 190gr, .300 Win Mag Nosler Trophy Grade AccuBond Long Range 190gr, .300 Win Mag Barnes Precision Match OTM 220gr, .300 Win Mag Hornady Superformance SST 180gr, .300 WSM Winchester Expedition Big Game 180gr, .300 WSM Federal Vital-Shok Trophy Bonded Tip 165gr, .300 WSM Hornady ELD-X Precision Hunter 200gr, .300 WSM Barnes VOR-TX TTSX Boat Tail 165gr, Nosler Trophy Grade AccuBond Long Range 190gr, Black Hills Match Boat Tail Hollow Point 190gr, Federal Vital-Shok Trophy Bonded Tip 165gr, Hornady American Whitetail Interlock 165gr, Nosler Trophy Grade Long Range ABLR 190gr. What about accuracy of the 270 Winchester vs 270 WSM? The Big Game Hunting Blog is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com, Amazon.co.uk, Amazon.ca and other Amazon stores worldwide. Since the 270 WSM uses a significantly shorter cartridge, you’d probably expect rifles in that cartridge to be shorter and lighter than rifles chambered in .270 Winchester. None of them have covered any new ground. Rifles in both cartridges are also extremely common. Bullet Style: AccuBond Use: Deer, Elk & Moose Sized Game Wildcatters soon produced the .30-338 Winchester and Norma Projektilfabrik, who were by now manufacturing ammunition for Weatherby, took the standard length basic Weatherby brass and necked it down to .30 caliber (7.62 mm) and called it the .308 Norma Magnum.
All sizes in inches (in) and millimeters (mm). In this article, I’m going to do a detailed analysis of the 270, 7mm, 300, and 325 Winchester Short Magnum cartridges and compare them to the .270 Winchester, the 7mm Remington Magnum, the .300 Winchester Magnum, and the .338 Winchester Magnum in an effort to answer the above questions and parse out the their true strengths and weaknesses so you can make an informed decision regarding which one will work best for you. We also want to note that all of the data here is computer generated. At 300 yards, all of these rounds still have well above 2,000 ft.lb with several rounds, including both .300 Win Mag and .300 WSM, still carrying more than 2,500ft. Still less than two inches. However, their .555″ case diameter is larger than those used by the 7mm Rem Mag and .300 Win Mag (.513″) as well as the .270 Winchester (.470″). In this section, we will look at velocity, trajectory, and ballistic coefficients of the .300 Win Mag vs 30-06 to give us the information necessary to draw some conclusions for when each cartridge is best used. Winchester 93.8 grains of H2O (6.08 ml) If it works for you, that should be all that matters. From this set of rounds, we do not see any pattern regarding rounds from each cartridge grouping together, and we don’t think we would even if we had twenty rounds from each cartridge. while burning 10 percent less powder; cycling through shorter, lighter rifles; being inherently more accurate; recoiling less; and killing like lightning cross bred with the hammer of Thor.
