Since then my personal .270 experience has included plenty in North America on big game up through elk and moose, and in Africa on elk-sized plains game. Since the introduction of the high performance Remington XP-100 and similar handguns chambering larger rifle cartridges, all 30 caliber MatchKings® have been used in handgun silhouettes and long-range target competitions.

This bullet was introduced in October 2015. However, I doubt the original 130-grain factory load attained its advertised velocity, especially in the Model 54’s 24-inch barrel, though it probably did get around 3,000 fps. Despite such skeptics, the .270 eventually became one of the two most popular non-military big-game cartridges introduced before World War II, the other the .30-30. A sleek 27 caliber elongated ogive and a final meplat reducing operation (pointing) provide an increased ballistic coefficient for optimal wind resistance and velocity retention. This is not simply a matter of landing either point-forward or sideways, because ballistic coefficient is also affected by how firmly a bullet stabilizes. While they are recognized around the world for record-setting accuracy, MatchKing® and Tipped MatchKing® bullets are not recommended for most hunting applications. This 135 grain MatchKing® bullet #1833 is the heaviest match grade bullet currently available in Sierra’s line in 270 caliber. When the .270 Winchester appeared in 1925 as one of the rounds in the company’s new Model 54 bolt-action rifle, the chambering apparently did not sell spectacularly. H-4831 also changed over the years because the original military-surplus powder was pretty much used up by the mid-1970s. The new powders tested were all double base and ranged in burn rate from medium to pretty slow. The really good news involves Federal, now back in the handloading component business after a several-year vacation. (These and other results were reported in “Different Batches, ‘Same’ Powder” in Handloader No. load, a 130-grain bullet advertised at 3,160 fps, was too fast and light for big game because they had grown up shooting the .44-40 and .45-70 and had just gotten used to .30-caliber bullets for big game.

Despite the appearance of many other rifle cartridges since 1925, the .270 still ranks way up there. Today Hodgdon owns the IMR brand and lists a top 130-grain velocity of 2,916 fps with IMR-4320 from a 24-inch barrel. When the .270 Winchester appeared in 1925 as one of the rounds in the company’s new Model 54 bolt-action rifle, the chambering apparently did not sell spectacularly. This occurred because many companies developed their loading data like optimistic handloaders do today – by adding powder until rifle or brass show signs of distress, then using the heaviest charge that “appears safe.” Speer, in fact, used the method for decades despite having copper-crusher test equipment, apparently because nobody at the company knew how to use it correctly. Out of my “popular hunting rounds” article, it’s easily my favorite. O’Connor reported very high velocities and fine accuracy with H-4831, and it soon became the .270 powder. Its Trophy Bonded Tip has been available since 2017, but now the company also sells the 136-grain Edge TLR, another bonded bullet with a solid shank but more lead in the nose and a hollow plastic tip for wider. Trajectory for Custom .277 140 TGK #4440 AMMO at 2960 Feet per Second. Although MatchKing® and Tipped MatchKing® bullets are commonly used for varmint hunting, their design will not provide the same reliable explosive expansion at equivalent velocities in varmints compared to their lightly jacketed Hornet, Blitz BlitzKing, or Varminter counterparts. Even in Litz’s “worst case” conditions (meaning sea level in colder temperatures), the 170 should stabilize in a 1:10 twist, and in the “best case” (higher elevations at warmer temperatures) it stabilizes pretty well, though ballistic coefficient will not be optimal compared to a 1:8 twist. Many loading manuals of the day listed very high .270 velocities, not only for H-4831 but other powders. They list 49.4 Grs. In another test, the old H-4831 with 130-grain bullets lost 150 fps when chronographed at 70 and zero degrees Fahrenheit. RELOADING MANUAL • 5TH EDITION 270 Winchester continued #1820 .277" 130 gr.

A major problem was that factory loads for the .30-06 featured a 150 grain bullet at an advertised 3000fps, a potentially harder hitting load than the .270 130 grain bullet. Combined with improved powders, all these new bullets make the old cartridge work better than ever. One surprise occurred during the powder-data search. A database of .270 Winchester handloads.

The flat trajectory of the .270 made 300- and 400- yard shots possible with iron sights, which dominated hunting until after the war, and the 130-grain bullet worked great on deer and wild sheep. Today’s Aussie H-4831 is the Extreme version and comes in two variations, one similar in appearance to the mil-surp powder and a “short-cut” version with granules about two-thirds as long, which flow more consistently through powder measures. The Mossberg’s twist in the standard .270 is 1:10, but I was sure the Berger would stabilize anyway. Shooters around the world will appreciate the accuracy and extreme long range performance of Sierra's 7mm 183 grain HPBT (#1983). Several have very high ballistic coefficients (BC), and due to their long ogives could not be seated anywhere near the lands and still fit inside the Patriot’s magazine.

For this report, I decided to define “new” as powders and bullets introduced in the twenty-first century.

Included in the tests were several monolithic bullets in the 110- to 140-grain range that shoot very flat at conventional ranges, penetrate deeply while ruining relatively little meat and recoil modestly, one of the often overlooked original virtues of the .270 Winchester. Most also included decoppering agents, another modern trend, though some .270-appropriate powders included decoppering agents as long ago as the 1920s.

Berger’s website twist calculator, based on the formula developed by the late Don Miller, indicates the average G7 BC of .343 will still be .320 from a 1:10 twist in typical fall hunting conditions in my part of Montana. This commonly happens with modern powders because they burn most consistently at higher pressures. Speer’s Manual for Reloading Ammunition Number 6 (1964) also draws the line at 49 grains. Powders were selected by my usual method, searching published data for the highest velocities for various bullet weights.
