.223 for TR

[AHPP]

I recall (hopefully correctly) that as well as .308/7.62, .223/5.56 is also allowed in TR.
1) .308/7.62 ammunition is normally issued in TR; what's the score with .223/5.56 ammunition?
2) Broader question. What (if any) are the constraints on rifle type?

[Dougan]

If you are shooting NRA TR competitions like the Imperial Meeting then it's .308, and most of the time the ammo is issued at the comp. I think there is a type of 300 yrd TR where you can use a variety of calibers (including .223), and also reload.

As for rifle restrictions - TR rifles are held unsupported, so no bipods, and have open sights front and rear - there are also weight limits and weight of trigger limits.

Anyway - Good question.... lets wait for someone who actually knows the details...

[AHPP]

I think you're thinking of ISSF 300m when you talk about open calibre competition. It's what the sheds on the left end of Century are for.
I'm talking about good old fashioned Bisley backbone TR.

As for rifle constraints, I wasn't clear enough before. I want to know whether I can shoot TR with an AR15. It's primarily a magazine fed rifle but can be single fed. Iron sights and sling of course so no problem there. I want to know about rifle weight, barrel length and trigger weight rules.

[Dougan]

Yes, thats right, the 300m stuff is shot from the sheds...and some impressive shooting too!

The 'Bisley backbone' stuff I believe is all .308, so would rule out the AR15 - but I don't know about rifle types (like I said..good question) - would any rifle chambered for .308 qualify, if it had open sights and was held unsupported....?

TR rules page 56.

TR – Target Rifle
150 Any bolt-action rifle which, in the opinion of the Shooting Committee, is
of conventional design and safe. All rifles must also conform to the following:
General: The rifle or all its component parts must be readily available in
quantity.
Weight: Maximum 6.5kg (14.32lbs) as used including all attachments except
the sling.
Barrel and Chamber: Suitable for firing any of:
a the standard 7.62 x 51mm NATO military cartridge
b the .308” Winchester commercial cartridge
c the .303” British Mk VII military cartridge
d the standard 5.56 x 45mm NATO military cartridge
e the .223” Remington commercial cartridge
Note: (a) and (b) are not necessarily the same, and (d) and (e) are not the same.
Attention is drawn to Appendix V.
Bore and Chamber Dimensions: The dimensions must not be less than either
CIP or SAAMI minimum chamber drawings (whichever is the smaller) other
than in (a) and (b) above where the following concessions are permitted:
the bore diameter must not be less than 0.298”.
the groove diameter must not be less than 0.3065”.
the throat diameter must not be less than either the bullet diameter
or 0.3085”, whichever is the greater.
the minimum throat length may also be reduced but only to such
an extent that the bullet of the cartridge in use is not in contact with
the rifling. See Appendix V Para 7f.
If reduced bore or groove diameters as above are used, only ammunition
developing an average max pressure less than 3650 Bar under CIP test
conditions may be used. NRA ammunition “as issued” will satisfy this limit.
Pull of trigger: Minimum 1.5kg (3.307lbs). Set triggers and ‘release’ triggers
are not allowed.
Stock and Butt: May be shaped so as to be comfortable to the firer. A thumb
hole for the trigger hand is permitted. Adjustable butt plates without hooks are
permitted. The depth of the butt plate curvature shall not exceed 20mm (0.79”)
at its deepest point. A hand stop is permitted.
Magazine: If fitted shall not be used except as a loading platform for single
rounds.
Muzzle brakes: Not allowed.
Sling: Must conform to Para 209.
Backsight: A variable dioptre eye piece or single correcting lens may be used
(but see Paras 206 and 207). One or more optically flat filters may also be used
in front of or in rear of the aperture. A flexible disc or eyecup may be used. In
addition a piece of flat material or a blinder may be fitted to the backsight to
restrict the vision of the disengaged eye.
Foresight: Any type which may contain a single clear or coloured magnifying
lens which has a minimum focal length of 2 metres (0.5 dioptre) but see Paras
206 and 207. It may also contain optically flat clear or coloured element(s).
Spirit levels: It is permitted to attach spirit levels or other level indicators to
the rifle.
Overseas competitors. Where reciprocal agreement has been reached, overseas
58 FIREARMS, AMMUNITION, EQUIPMENT and TARGETS
competitors may use, in competition, target rifles which conform to their home
country’s Governing Body’s rules, during their first three months in the United
Kingdom, provided that they conform to the maximum weight, chamber
dimensions, minimum trigger pull and sight specifications given above. Out
of competition only the minimum trigger weight condition must be complied
with. Telescopic sights are not permitted. The rifles must be suitable for use
with any ammunition supplied by the NRA (see Appendix V).
151 In NRA TR competitions where ammunition “as issued” is specified:
a only 7.62 x 51 mm or .308” Win target rifles may be used.
b only ammunition issued by the NRA, without any modification,
may be used (see Para 544).
c NRA issued ammunition will conform to CIP dimensions for Win
.308” and will develop a maximum average pressure under CIP test
procedures of 3650 Bar. Competitors are responsible for ensuring
that their rifles are safe to fire such ammunition.
Ammunition “as issued” is specified for all TR competitions in the Imperial
Meeting, and at some other NRA events. At other times any ammunition may
be used, all users of which are responsible for ensuring that it is in every
respect safe and within range safety parameters (see Appendix V, Appendix VI
and Paras 256, 288 and 544)

Hope this helps.

That's what I was after. Thanks.

Bad luck!

Ah. That'll be 99% of comps then.
No big deal. I'd probably have never got round to it and I have a .308 anyway. Still interesting though.

Once upon a time the main Bisley calibre was supposed to mirror the service calibre. Hence .303 then the move to 7.62 NATO. However the move over to 5.56 was clearly a step too far. Perhaps the NRA should have created a set of comps for the .223 and thereby a) promoted the development of service shooting and b) supported the development of the service calibre?
