![]() ![]() There is actually little to separate their performance specs in short distance shooting. The 300 and the 308 have the same bullet diameter of 0.308”. Both the 300 Win Mag and the 308 both come from Winchester as said hence sharing some technical similarities. Now that we have reacquainted ourselves with these two cartridges basically, it is worth pointing out that both cartridges have similarities they share. Subsequently, the US military didn’t use the 7.62×51 NATO (the modification of the 308 Win Mag) for long but many hunters weren’t any less attracted to the 308 all the same, hence it is very much still in use today. It was this modification that took the place of the 30-36 chambered rifles that was used by the US military when it went on intervention in Vietnam. Even the US military adopted the 308 Win Mag, then they modified it into the 7.62×51 NATO. Many hunters liked the 308 upon its production. The 308 was produced by the same Winchester around 1952. The 308 also is very popular in the hunting community too. This is seen especially during long-distance hunting. It is famous for its uncommon compatibility with the 30-cal bullet.Īlthough the 300 is new when compared to many other cartridges from the Winchester production line, it is very much accepted among hunters essentially for its velocity, the range of options it gives you when hunting and other features. I have avoided the more modern smooth shanked monometals on purpose- so no experience with them.The 300 Win Mag is produced by Winchester, coming into use around 1963. And in doubles, it may be necessary to crimp to prevent bullet "pull". And in heavier recoiling rounds in magazine rifles, it is almost imperative to crimp to avoid bullet "setback". I have had no issues crimping any of the monometals. The Lee collet type Factory Crimp Die is the best to use. My experience with the banded monometals includes 30, 338, 416 and 458 calibers. They have been very predictable for pressure vs velocity and it has been easy to develop accurate hunting loads with them. I've also found, without exception, the modern banded designs to be as accurate if not more accurate than the conventional heavy jacketed and bonded premium bullets. The modern banded monumental brass and copper bullets by the various manufactures are like the difference between night and day with the early smooth shanked Barnes X. The original, smooth shanked Barnes X bullets were horrendous for fouling, poor accuracy and pressure spikes. I've found the banded solids like the TSX to be no more or less fouling than conventional jacketed bullets. What is the inherent accuracy potential of the rifle? And if it is capable of <1" 100- what load? How does it shoot a comparable lead core premium like an A Frame or Woodleigh?Īs to jacket fouling?. 308, using Sierra MatchKing bullets, it it isn't me.ĭo I need to try a different powder? Should I continue experimenting with the seating depth? 6" groups from the same set up with my Remington 700 Varmint in. For testing, the gun is sandbagged in place on a benchrest. I am wondering what I can do to improve the accuracy of my loads at this point. Those rounds are too long to fit in the magazine, and there doesn't seem to be much difference in accuracy. For the 69.3 loads, I measured the chamber with the Hornady gauge and seated. All the loads except the 69.3 were seated to 3.340", which is what it says in the Barnes manual. I didn't really measures group size the first day, but for the second set up loads, group sizes at 100 yards were as follows:Īverage group size across all 8 groups is 2.38". The velocity numbers are based on a 10 round average for each load. During both ranges session so, far, the air temperature was about 27 degrees Fahrenheit. My groups are averaging 2.3" at 100 yards. I have the velocity nailed with 69.3 grains (the max load out of the Barnes manual), but I am not presently satisfied with the accuracy of the load. My goal is 3000 fps and sub-MOA groups off the bench. I am developing a load using Barnes 180 gr. 300 Win Mag, topped with a Leupold VX 3i 4.5-14 x40 in Warne rings and bases. My primary rifle for the trip will be a Winchester M70 Super Grade chambered in. I'll be hunting plains game in the Eastern Cape province of the RSA this coming June. Hello: I am preparing for my first African hunting trip. ![]()
