300 Norma Mag Background
The 300 Norma am chose by SOCOM the brand-new state-of-the-art Sniper Rifle (ASR) rivals because of its impressive additional ballistics.
Maybe you are inquiring, a€?Isna€™t every round chosen due to its ballistics?a€? Effectively, yes-and-no.
Because you can know, there are certainly three kinds ballistics, inner, additional, and terminal.
- Inner ballistics makes reference to what’s going on inside firearm
- External ballistics means what is happening between the firearm while the target
- Terminal ballistics concerns what takes place whenever round interacts utilizing the target
Frequently times tend to be preferred (by folks, authorities department, or army party) due to their proportions, pounds, interior ballistics, and/or terminal ballistics.
Inside ballistics is really important when stuff like reducing recoil or capitalizing on cask lifetime are important. And terminal ballistics tend to be a key point whenever there are concerns about self-protection or tracking a€?stopping electrical power.a€?
Cartridge Sizing
Large an ammunition is essential when the consumer is intending to increase power or reduce the dimensions of the firearma€™s measures. The weight of a cartridge is extremely important if several beat must be taken for very long distances/periods of times.
The 300 Norma mag is reliant away from the 338 Norma Mag situation necked to take a .30 quality round. It’s also supported from the the exact same elder cartridge since the 338 Lapua maga€¦.the 416 Rigby. Therefore a bolt with a substantial face will become necessary which means a sizable motion (and a large/heavy rifle).
300 Norma Mag Ballistics
The 300 Norma Mag introduces a 220gr .308 round at just over 3,000 fps. Thata€™s 4,400 ft/lbs of energy!
The 300 Norma Mag really shines when it’s shooting often the 230gr Berger Hybrid bullet a€“ this topic features an out-of-this world today 0.743 Ballistic Coefficient (BC)! (If you decide toa€™re going to discover BC, visit Chapter 10 of this Long Range firing guide) Once loaded up to 3,000 fps, this topic from 300 Norma Mag will stay supersonic over to 1,500 m! This can be in terms of a substantially weightier 300gr SMK bet regarding a 338 Lapua causes it to be earlier moves subsonic! Even though the 300 Norma will for sure have actually 80percent associated with the stamina associated with 338 Lapua at that length with those bullets, it can nevertheless survive around truthfully, with much less recoil. Another benefit toward the 300 Norma Mag may be the as a whole distance are quicker than the 338 Lapua Mag a€“ it’s effectively identically amount as being the 300 Win Mag.
They takes flatter possesses less breeze drift than ita€™s best counter-parts, the 338 Lapua as well 30 Nosler.
However, it is definitely a larger size cartridge versus 30 Nosler (superior thunderbolt face/action and fewer newspaper ability), it falls behind to the terminal ballistic energy from the 338 Lapua (until it captures up close to 2,000 yards), and, possibly my personal main negative feedback, it’s not at all an even cartridgea€¦. it is far from made use of by additional people in our military nor any other army.
Very, the 300 Norma try a wonder-round on paper. And, it really is lighter recoiling versus 338 Lapua. But Ia€™m perhaps not convinced that it’s wise to chase the latest/greatest and best executing round. All things considered, therea€™ll continually be a thing that comes along afterwards that will feature greater outside ballistics. As soon as that takes place, the military (especially) shouldna€™t battle to consider the new sequence with the price of unique rifles, new ammunition supplies, and classes.
