Не могу понять.
Раньше, когда говорили про HVA речь шла о 21 Дж.
Здесь в правилах кубка АПБР сказано уже про ограничение в 20,34 Дж для HVA.
Полез читать EUROPEAN RIMFIRE & AIR RIFLE BENCHREST SHOOTING FEDERATION OFFICIAL RULE BOOK
Там вроде про 21 говорится.
Цитата:
3. Heavy Varmint Air Rifle Class A - is any rifle having a manually safe manually and mechanically
(including electronic triggers) operated firing mechanism, a weight restriction of 15 lbs is set
(including attachments – scopes, muzzle devices, etc). Any air regulator can be used as long as it
is integral within the air cylinder. Any modification may be made to the rifle and any magnification
scope may be used. Factory stock or stocks that meet ‘Stock Clarification’ rules may be used (see
APPENDIX G). Return to battery shall NOT be permitted. Muzzle brakes, muzzle flips, barrel weights
or Harmonic Tuners are permitted. There is no restriction on cylinder size or capacity as long as 21
Joules or 15 ft lbs maximum power is retained and it is integral within the rifle. (Separate Air
Cylinders are not allowed, the cylinder must be part of the rifle and the overall weight). Shooting
Distance 25m. (0.177 and 0.2 scores plugged by 0.22 calibre gauge.
Упоминание про 20,34 нашел там только в разделе про заправку:
Цитата:
K.6 Air Rifle filling station
The hosts must ensure that adequate safe facilities be available at the Range as to enable
competitors to fill the air rifles to the required capacity 8.25 Joules or 6 ft lbs 16.27 Joules (12 ft/lbs
20.34 Joule or 15 ft/lb .200 and 300 bar filling facilities must be available at the event.
Так сколько должно быть-то?
Разница между 20,34 и 21 Дж составит 5-7 м/с полуграммовой пулей.
