  2. when is a bullet a bullet

    in Bullets, Cartridges and Reloading

    Posted

    Wikipedia "A bullet is a projectile propelled by a firearm, sling, or air gun. Bullets do not normally contain explosives[1], but damage the intended target by impact and penetration. The word "bullet" is sometimes used to refer to ammunition generally, or to a cartridge, which is a combination of the bullet, case/shell, powder, and primer"

    From what Im reading you have to account for the ammunition and components you have. Over her i can work into a gunshop, produce my licence and buy prettymuchwhat I want. When I was shooting F class it was 2 kg of powder and 500 or 1000 Amax projectiles at a time. Things sem a lot different over there

    Hi,

    I have a heavy barrel 17 MKIV built on a sako A1 action. Cheap to run, gives me 3800fps with a moderate load and 25gn projectiles. Much quieter then the 17 rem, much easier on barrels and cases. Extremely accurate and kills way above its size. Wind is nowhere near the factor that a lot of people think as the bullet gets downrange extremely quickly.

    Cheers :good:

    Hi Macca,

    Thanks for the reply, its stamped on the left side of barrel BRNO MK1 .22 cal LONG RIFLE Where the barrel meets the receiver are what look like proof marks and the number 52. It came with two all steel magazines a 5 and a 10 shot, and there is an extended magazine catch fitted. The barrel has front iron sights and a slide in rear iron sight which is not fitted as there is a Bushnell scope mounted, but was included in the sale along with the original magazine catch.

    I think i will see if i can get the stock refinished (im not too good at woodwork)as its not too bad just a few dings and scratches, the rear sling stud is missing though but i presume i can just screw a new one in its place.

    Hi Dave,

    Sure looks like a model 1. The curve on the magazine well plate and the position of the safety give it away.The 5 shot mag will feed better than the 10. Out here the steel 5 shot mags are sought after to replace the current plastic things. The 52 indicates it was manufactured in 1952. If you want to improve your trigger I can send pics on how its done - the trigger is not like current ones and I dont think there is a kit available. You have an excellent rifle - look after it and it will give you another 60 years of service.

    Cheers Ian

    Hi Dave,

    If is marked BRNO and is a model 1 then you have probably the best brno/cz made. Out here model 1 brno's are prized above all others as the metal work is far superior to the current guns. It should have a date stamp on the left hand side of the barrel just in front of the receiver, mine is dated 1950 and still shoots subhalf inch groups at 50m off the bench. The magazine well/trigger guard is different to current models .It has a longer trigger guard/magazine well plate as well as a curved section that the currnent cz's dont. If it is a model 1 or an early model 2 then you should find a ball bearing at the root of the bolt handle. Doubt if you will find a plastic (yuk) stock for it.Do the wood one up - strip with paint stripper, gently rub back, steam out any dings and refinish with red root oil.

    Cheers :rolleyes:

  11. Reloading Advice please?

    in Bullets, Cartridges and Reloading

    I have 3 presses - a turret simplex master an O frame Simplex master O frame RCBS. I use them all. I reload 8 calibres. O frames are far more rigid than turrets and cast iron far more rigid than aluminium. You can "spring" aluminium presses on large or badly lubed cases. Lee collet dies are very good, redding competition bushing dies are excellent. A custom made gun will only shoot its potential when fed with high quality handloads - fed **** it will shoot ****. Quality handloads taylored to a gun will invariably shoot to guns potential - target or hunting. There are guys in our club shooting possibles and double possibles in F class open at 300 metres(10 shot groups meauring 3/4 moa at 300M) and not Quality guns with quality handloads give quality results.

    Cheers

    Woahhhh!! Sounding complex now! :blush:

     

    I'm 12 months away from reloading my own stuff (house move) so small, simple, experience building is probably the level I am at.

     

    223 or Hornet are the fron runners for me so far! Why cant I find new Hornets? Is that a slang for the calibre or a brand name?

    The Hornet is more obsolete than the 222 - not many new guns around - also older guns take 223 projectiles rather than 224. Case is headspaced on the rim so if you have a oversize chamber then you can suffer with head separation. Brass is very thin and case has little shoulder - sometimes you can crush the case while seating the projectile. There are still many firearm manufacturers making 222's and ammo is still made. I have a 17mkII, 17MkIV, 223, 22br. They are work guns. These will all do what this thread has been talking about (the BR creates rabbit red mist though)

    Buy a good secondhand 222 and load it back to hornet velocities using 35 grain Vmax projectiles - kills foxes and doesnt destroy head shot rabbits. Easier to reload than the hornet. If you want to go exotic - 17rem fireball(17MachIV) or the ultimate small caliber rabbit /fox gun (and you will have to have a 222 rechambered to this) 221 fireball.

    Cheers

    125 metres on foxes with the HM2 is really not on,

     

    what would concern me slightly is availability of ammo as it is a little used caliber and not reloadable.

    You would be surprised at what this calibre will bring down with one shot kills.

    I believe there will always be one or two manufacturers. CCI and Federal are made on the same machines and I believe you have Eley over there

    Cheers

    I have a Kimber in 17 Mach II. Out here the ammo is cheaper than the HMR. I wouldnt swap this rifle for the world. Excellent POA gun to 125 metres for foxes in the chest. Excellent head shot rabbit gun to 100m. Significantly quieter than the HMR. If this calibre had been introduced before the HMR then it would enjoy far more popularity.

    Cheers

    what length barrel is the 22br to push 3700 fps tho ? :good:

    Its a full 24", tight bore fitted chamber max load of BenchmarkII.Stock is custom thumbhole (still to be finished) Has a custom built mod using venturi gas flow principals of my design. Its bedded past the knoxform to help support the mod.Reduces noise to somwhere between a 22 magnum and a 22 hornet. At the moment it wears an 8x56 kahles but eventually when money permits a 3-10 or 3-12 by 56 European glass with illuminated reticle.

    I have both a Sako heavy barrel 223 and love it and now a 22BR built on a trued rem 700 action timney trigger (14ounces) target barrel with a 252 fitted neck (no neck or full length sizing) - its pushing 50 grainers out at 3700 fps and is starting to produce sub half inch groups. It is far more accurate than any other 22 cal centerfire that I have owned. At that velocity a 50 grainer is giving 1540 ftlbs of energy. Had to put a pound of lead in the butt to counter the weight on the front of the barrel. I think this will be one serious spotlight (lamp) gun when its finished.

    Cheers

    So……just to complicate matters where does the forum think the .222Remington Magnum fits the bill.

    (For those amongst us not familiar with this cartridge, it’s the parent case for the .204Ruger.) :blink:

     

     

    G.M.

    It sits between the 223 and the 5.6x50 magnum. It was one of the original contenders for the military job that the 223 ended up with.

    There is a distinct difference in performance between the 222 and 223 - in reality the 223 will stretch your range about 50 metres - there is around 250fps difference btween max loads for 50gn projectiles. In terms of accuracy in a hunting or varmint rifle there will be no noticeable difference.

    Cheers

    All .22 calbre but all .224 (although the .22H (the 3rd one from the left may be .223)

     

    I believe from right to left they might be 222, 221 fireball, 22 K hornet, 22 hornet, not sure of this one but it could be an ackely 221 or a 22 eichelberger dart and on the left the 22 magnum

    Hi,

    the pic shows four of the cases mentioned in my previous post -they are the 221 fireball(left)then 222, 223 and 22BR. They all take 224 diameter projectiles. Names for cases can be very frustrating , none of these indicate bullet diameter or case capacity while other cartridge designations do. There is also dual designations such as the 308/7.62 and 223/5.56 situation.

    If you want a good source of reloading data and for the 222 and 223 and you have accss to benchmark (ADI Benchmark 2) or 4895 (ADI AR2206H) then check this site out - the data is accurate and free. http://www.adi-powders.com.au/handloaders-guide/

    The modern hornet, 221 fireball, 222, 223, 22/250, 22 PPC, 22BR, 220 swift, 22wssm, 5.6x50mag and other wildcats all use .224 projectiles. The 223 is in fact as accurate as the 222 but was never developed as a short range bench rest cartridge (the PPC family prevented that). It has been developed as long range target cartridge for full bore, F class open, and F class standard and is competitive out to 800 metres (80 gn vld projectile 1 in 8 or 1 in 7 barrel usually 30+ inches long)

    Reamers are relatively cheap (about $150 from Pacific Tool and Gauge in the US) Modern barrel steel -chrome moly or stainlees dont change between different calibres -that would be an exhorbitant cost to firearm manufactures. Out here barrels are re reamed all the time - a target barrel in its life may have been cut and rechambered 3 times to eliminate throat erosion.

    Cheers

    Hi,

    222 and 223 both excellent cartridges. Back in the 60's and 70's the 222 was the benchrest cartridge. There is a slight increase in case capacity between the two which will give the 223 about 250fps increase in velocity for a 50gn projectile. The 223 is available from more rifle manufacturesrs and in more models. Ammunition availability and variety is also greater with the 223.

    Agood second hand 222 at the right price is still a very good buy but for a new gun go for a 223. Remember a good chamber reamer will change your 222 to a 223 easily (gunsmith of course)

    In the end charlie won't be able to tell the difference.

    Cheers
