NEW CONCEPT IN F-TR RIFLES FROM FOX FIREARMS There has been much debate in F/TR circles as to the relative benefits of 155 grain and 210 grain bullets, in minimising wind drift for long-range shooting. The exponents of the 155g projectiles cite a reduced flight-time for the projectile to be subjected to cross-winds, whereas the 210g fanciers pin their faith upon nothing more than physics.
Many who prefer to use the 155g agree that in windy conditions, the 210g projectile will have the edge. This creates a dilemma for those ordering a new rifle, or considering re-barrelling - whether to opt for, say a 1 in 14 twist to stabilise the 155g bullet, or a 1 in10 twist to stabilise the heavier bullet.
Based upon current leanings, the only answer is to have two F/TR rifles; one with a slow twist for use on still days, the other with fast twist for use in inclement weather.
However, Fox Firearms, after experimenting with side-by-side double rifles, which were abandoned due to weight and bedding
problems, has come up with an ingenious solu- tion, based on gain-twist rifling.
They have taken a gain-twist barrel, starting at 1 in14 and increasing to 1 in 10 and chambered it at both ends, with two receivers fitted, and using a single common bolt. A Picatinny rail is fitted to both receivers and one ‘scope with QD rings can be used. The stock will accept either action simply by removing/replacing the bedding screws – a process taking but a few minutes and can be accomplished on the firing-point immediately prior to the shoot.
In tests, the ‘muzzle-end’ receiver seems to act as a barrel harmoniser, if anything enhancing accuracy and eliminating muzzle-flip.
Leaving nothing to chance, Fox are producing 40” double ended breech safety flags to accompany these rifles.
We hope to conduct a full test in a later edition of Target Shooter.
