    I'm thanking of building a blackout 300 what would be the best twist rate for that?

    • @CloverTac
      @CloverTac  Місяць тому

      it sorta depends on what you are primarily going to be running. the blackout cartridige can range from 90gr to 275gr so there is a lot of ground to cover. then barrel length makes a bit of a difference too. longer barrels can typically get away with a little slower twist rate. for say anything 115gr to 168gr, 1:10 or even 1:8 seems to do fine for me and for the heavier stuff, say 220gr plus, i go at least 1:7 if not faster. seems i see a lot of 1:10 or 1:7 options out there, so to simplify that, would say go 10 if primarily lighter and 7 if primarily heavier. keep in mind that while a slower twist may not stabilize a heavy projectile, a faster twist really only runs into issues in regards to causing jacket separation, etc on light projectiles. this isn't an issue at all with most bonded stuff, legit full jacket or solid copper right? so you can typically get away with faster better than you can with a slower twist. now, are you even more confused? 🤣😂 hopefully not, sorry for the ramble here.

    • @CloverTac
      @CloverTac  5 місяців тому +2

      not being ugly but first wanna ask... did you watch the video at all? i explain why twist rate matters. it has little to nothing to do with drop. what will happen is a heavier projectile requires a faster twist to stabilize. if the projectile is wobbling during flight, it is not going to go as far cuz of drag, be as accurate, etc. compare it to a quarterback throwing a football, which is the better way to throw it, loose wobbly or nice tight fast spiral? now with using a really light bullet and a fast twist, there is a chance it spins too fast and can separate the jacket, which is what makes the projectile more areodynmaic, from the core. so a 1:9 in my opinion is too slow for a 75gr but there are all sorts of other factors at play, so it may do alright. probably a good idea to disconnect the idea of twist from any type of distance... while an optimally flying projectile will typically perform better as far as disatnce, doesn't matter if it is so wobbly it is inaccurate or smacks your target sideways (call keyholing). hopefully this helps ya understand better

      that is a good question but as explained here (if i recall, this video is older after all) it does depend on the weight of the projectile you plan on running and to an extent the purpose. for general purpose 1:10 to 1:16 seems to be what most manufacturers go with as those handle 115gr to 147gr well enough. but i have seen twists go as high at 1:24 or even 1:32, especially when running special loads, special projectiles in a competition setting

    I wonder how do they shot m193 (55 grain) using barrels with 1/7 twist rate in the military. Isn't it too fast for the light bullet?

    • @CloverTac
      @CloverTac  2 роки тому +2

      so first off, the M16 has been issued in a variety of barrel twists from 1:7 to 1:12... so my first question would be do you know that those who are issued M163 are using a 1:7? i do know that that in the civilian world, a 1:8 or 1:9 seem to be the most common twist rates for the comparable (not identical AR-15). i obviously have no military experience... so i cannot answer from that perspective. from my experience though 55gr will work in a 1:7, much better than say a 75gr would work in a 1:12. the M163 is a FMJ and the biggest issue is eee with light projectiles and faster twists is jacket separation... not nearly as abig of an issue as stabilization. and FMJ projectiles, again in my experience, do not tend to separate as easily as projectiles with an open front, like a SP, HP, etc. and keep in mind to that an OTHP is a match greade style HP, not a defensive style HP. i know that got off into projectile types a bit there, so hopefully wasn't terribly confusing. great question!

      that is a major oversimplification when it comes to twist rates, but true at least to some extent. velocity and spin doesn't have to be present IE cannon balls, smooth bores, etc but when maximum accuracy is the end game, yup, all cards are on the table. twist rate doesn't reall affect velocity to a certain extent but it the cornerstone of spin and the weight of the projectile you need to spin, and to some extent the length of the barrel will dictate what twist can provide the best stabilization and thus accuracy for a given round. there, did i complicate your over simplification enough? 🤣😂

      i thought AKs were genearlly somewhere between 1:9 and 1:10 and wasn't aware of the principles of twist range being different somehow, barrel twist should just be barrel twist as it has little to do with caliber, platform, etc, all about the length and weight of the projectile verus the proper twist to stabilize said projectile (whatever that might be)

    • @CloverTac
      @CloverTac  2 роки тому

      are you asking if you can find AKs with varying twist rates? i would say yeah, probably so, caliber will play a role there as well as grain weight ammo they are designed to fire. but everything equal, meaning 7.62 vs 7.62 variant, they should be pretty close to the same, within a inch or so anyway.

    • @CloverTac
      @CloverTac  2 роки тому +2

      just becuase twist rate is not mentioned does not mean it does not exist. if a barrel is rifled, there is a twist, there has to be, it is a matter of phyics. unless we are talking about a smooth bore like a shotgun anway. the physics also does not allow for one twist to stabilize everything. the heavier the projectile, the faster the twist needs to be for stabilization. for lighter projectiles, a faster twist can be used, can't really over stabilize anything so in a sense that could be called universal but if you shoot a lighter projectile in a faster twist, there is the likelihood that the fast twist can spin the jacket off the projectile... which is not good and is not normal, so would negate the whole universal concept.

    I wouldn't knock a 1:8 twist out of a 16" into a particular category of bullet grains. This seems like the Goldilocks/Jack of all trades, master of none twist and length. Seems well suited to 55 grain and 64 grain, but can handle more. (speaking for .223/5.56 only) Anyways thumbs up.

    • @CloverTac
      @CloverTac  2 роки тому +2

      faster twists can typically handle smaller projectiles, the only issue you sometimes get, depending on the projectile is jacket/core separation due to that increased spin and typically a high velocity as well. only so much spin is needed for stabilization, after that it is wasted motion in a way. as with everything, factors can cause all sorts of variations but you did admit here "master of none" so at least you are being honest. just because it works doesn't mean it is optimal you know?

      for some reason, seems we are going way down the road of AR, when this videos is about the twist on all rifles. so maybe i don't go AR and if i do, maybe i go with an alternative caliber. so given my own choice, probably going with my sbr 8" 300 blackout with a 1:10 match barrel that is mainly becuase a 308 caliber is going to be more effective in my opinion and more things. if we are talking about 556 specifically, probably going with an 12" an 1 in 9 twist. of course my lever 44 magnum is a good choice for a lot of things too. it it really hard for me to pick just one firearm, i own many and they all have very specific uses..... thankfully i don't see a situation where i will ever need to do that 🤣😂

    • @CloverTac
      @CloverTac  2 роки тому

      good question, yes, obvioulsy there is a relationaship with total length since one twist in x number of inches (length measurement). as far the having two different length barrels with differen twist achiece the smae complete twist...it does not mean it is equal. achieving a complete revolution faster means the projectile is spinning faster. heavy projectiles need more spin to stabilze, as does longer projectiles (typically) and the copper jackets on lighter projectiles can spin completely off the lead core with too high of a twist rate.

    • @CloverTac
      @CloverTac  2 роки тому

      since you mention total barrel length here and i don;t really know you firearm education level, wanted to point out that up to a certain poin, barrel length does play a roll with the maximum velocity of a projectile.having enough barrel length to completely burn up the powder behind the projectile befoe said projectile leaves the barrel is of course optimal for that particular cartridge as far as vecolity. oh and also worth pointing out with the previous quesion that a longer barrel with the same twist rate (meaning more spin on the proper projectile) will typically yield better accuracy. what is interesting with this realtionship is that it is all about getting more spin as more velocity will typically end up making things less accurate. i know this can all get crazy and may take some time to understand but hopefully this in addition to the answer to your questions will help.
