Tot hi que fa temps que no en parlo, en temes de recàrrega de munició no es pot deixar res a l’atzar. Totes les variants que necessitem cobrir estaran probablement ja estudiades i ben documentades, així que si no tenim MOLT clar que la variació que pretenem fer és factible, el millor és no fer-la o buscar informació, que segur que hi és.
Convé recordar que variacions en el tipus de punta (recobriment, pes, base, material…), en el tipus de vaina (marca, material, nova o recuperada, longitud, diàmetre, amb gas-check…), en el tipus d’iniciador (marca, càrrega, diàmetre, col·locació…), en el tipus de pólvora (marca, quantitat, pes, tipus, volum, si està ben guardada…) i totes les combinacions possibles entre elles, com l’enfonsament de la bala, el tancament de la vaina, la longitud i el pes total de la bala… tots aquests paràmetres ben ajustats ens condicionarà un resultat òptim o per contra un problema d’alimentació en el millor dels casos… o quelcom més greu si ens situem en el plànol de les desgràcies, passant per la inutilització de l’arma, evidentment.
Donat que la xarxa cada vegada ens facilita més l’accés a tot tipus d’informació, la recàrrega no es podia quedar endarrera, i la casa comercial Hodgdon, fabricant americana de pólvores, ha decidit publicar la seva base de dades interna per a gaudi de tots els aficionats o professionals… que treballin amb subministres americans de la marca Hodgdon, IMR i Winchester. Bàsicament posen a disposició del públic un buscador molt eficaç per a combinar mil i una possibilitats per a cada calibre, dins d’aquestes marques.
Per exemple la informació que serveix per al calibre 9mm Luger és la següent:
