Rule F2.3
An F/TR Class rifle is limited to .223 Remington or .308 Winchester calibre chambers or
their commercial metrification equivalents. Chamber dimensions must conform to SAAMI
or CIP dimensions. Ammunition may be commercially made or hand-loaded as defined in
Rule F2.24. There is no restriction on bullet weight. The F/TR rifle class is limited to the
use of an attached bipod and/or a sling as front supports, optionally together with a rear bag
none of which provide a positive mechanical means of returning the rifle to its precise point
of aim for the next shot . The overall weight must not exceed 8.25kg including all
attachments (such as, but not limited to, its sights and bipod, if any). NB: An ‘attachment’ is
defined as in Rule F2.2. All other Technical Rules apply.
Rule F2.16
The F/TR rifle bipod and rear bag may not provide a positive mechanical method for
returning the rifle to its point of aim for the previous shot. The rifle, bipod or rear rest may,
however, incorporate an integral mechanism for raising and lowering either the butt or foreend
provided that it does not contravene rule F2.3. above.
So one rule states bipod and rear bag. The other rule says a rear rest may incorporate an integral mechanism and long as it does not contravene rule F2.3.
One rule says it must be a bag, another rule says it may have a intergral mechanism. Unless the intergral mechanism is inside a bag one rule contravenes the other.
Any you guys thought TR had a lot of rules.
