This created a compact and powerful package ideally suited for 180-210 grain bullets. Advertised as a non-magnum cartridge with magnum energy, it is made by necking. This was the first time Federal attached their name to a caliber. 33-08 wildcat, effectively renaming it the. Take a Look at the 8.6 Blackout Ballistics Here! The. Using supersonic loads, Kevin Brittingham shocked everyone by taking the 8.6 Blackout to Africa and taking a Cape Buffalo with it, widely considered one of the world’s toughest animals. The 8.6 Blackout is good for hunting all-sized game animals at subsonic velocities. Currently, the ammunition producers are loading supersonic loads with 210 gr bullets and subsonic with 288-300 gr bullets. The 8.6 Blackout was designed for use in semi-automatic rifles, specifically the AR-10 platform. 338 diameter bullets in standard 7.62 NATO Magazines without modification. It is a trimmed-down 6.5 Creedmoor case that is necked up to accept. The 8.6 Blackout, also known as the 8.6 BLK, 8.6×43, and 8.6 Creedmoor, was developed and invented by Kevin Brittingham and the crew at Q, Discreet Ballistics, and Hornady. Other than looks, the two cartridges are very different.ĭespite being very different, they both fulfill their unique roles within the hunting world. The 8.6 shoots a heavier bullet much slower than the 338 Federal. However, it differs from the 338 in both bullet weight and velocity. The 8.6 Blackout is closely compared to the 338 Federal. It wasn’t long after the 8.6 was introduced that people started to identify that it was almost identical to the. Often referred to as the 300 Blackout’s big brother, it fills the same subsonic role in an AR-10 platform. The 8.6 Blackout is quickly becoming the new hotness in the cartridge world. If that leads to another 100fps of muzzle velocity with good brass life, the 300 Norma becomes even more attractive.The 5.56 NATO compared to the 8.6 Blackout. The advent of Lapua brass in 2018 for the 300 Norma is a major development, and I expect it will accommodate higher pressures than the Norma brand brass with ease. The Lapua will have less wind drift at all ranges, significantly more energy at all ranges, and superior ballistics beyond 1500 yards.
The Lapua really shines in a properly throated single shot rifle with COAL in the ~3.9+" range.Īssuming a 230 Berger at 2950 and a 300 Berger at 2850, performance is close between the 300 Norma and 338 Lapua. The Norma magnums allow you to seat the bullet in an optimal position while still fitting in a magazine. Even with a CIP length 338 magazine, the length of the Lapua case forces you to push a 300 grain bullet deep into the powder column (a problem that will only be exacerbated by the forthcoming Berger 329). In my opinion, the primary advantage of the Norma magnums (both 300 and 338) is that the shorter case is much better suited for repeating actions that must feed from a magazine. Cases are about the same cost and bullets aren't much different so where is the savings? I can't see a lot of difference in the cost of loading the 300NM vs the 338 LM. I've found that the privi partizan and hornady brass lasts longer in the 338 lapua than the norma so why pay $2.50 a case from norma when its not as good? I've never had much luck with norma brass either.in any cal. Some of the shooters are using 338 LM Lapua brass to make up the 338 or 300 norma cases. All are hoping Lapua starts making brass for the round. Some have gone to the hornady brass which is not only cheaper but seems to work as well and lasts longer. I've had a number of customers who I've made up 300 NM barrels for that have complained about the norma brass being soft and short lived. That is because the 338 and 300 Norma Mags are both based on the 338 Lapua Mag case shortened and or necked to fit the 30 cal. In this case they're saying that the case head for the 300 NM is the same as the 338 Lapua Mag. Click to expand.The bolt face is the face of the bolt.the front end that supports the case head.
