Hi all,
I still can’t get any comfort from comparisons to the 17 Rem and other calibres, and bullet types. It stands alone; it doesn’t borrow from other standards. This cartridge has been around since 1971 and the 17-223 before it.
The Australians went ga-ga on this rifle for the fox fur trade, and nowhere has it been more popular then there. Why I ask? Because it was designed to be specific, with a cartridge and barrel delivering, high velocity, flat trajectory and predictable results on fur.
Remington’s data for this cartridge is 4,040fps, in a lab pressure gun perhaps! I have had several 17’s in the shop, and none of them have strayed far from 3,900 with factory ammo. That said, thousands of shooters have used factory ammo and earned thousands of $. My purpose in home loads, was to emulate the factory round to achieve the same effects. This where I am now, and 600 plus foxes are not here to testify.
I don’t say that 400fps extra will get the bullet deeper, in my crazy way I am saying the loss of that 400fps takes you out of the design criteria for this rifle, velocity + rotation = hydro static shock. Starting a 25grn bullet at 3,600-3,700fps does not work for me! At 3,900fps at muzzle, I get 3,390fps at 100yds and at 200 its 2,781fps, at this point there is a stored energy of 429ft/lb, c’mon that’s not bad for a 25 grn bullet.
All I can rely on is what works for me, what works for you is fine too! My reason is this, the effect of the kill is not at the muzzle, it is out a long way from you, you are asking a 25grain projectile to reach and kill out to 300yds. A tremendous amount of pressure is required, to propel a light projectile a long way! The design is spot on for this calibre, deviate from that and the results are unpredictable.
