Manufactured in house these are SAAMI Spec. Conversion adapters, if there is a corresponding calibre in a pistol for your rifle, we can make the adapter, shown are .303 Brit to .32 ACP adapters, the .32 Colt Auto round is a very close match to .303 Brit and this rifle calibre lends itself to easy conversion. We can supply these in .32 ACP or 32 S&W Long, other cals for instance are .45 ACP in the 455\/570 Martini Henry or even .455 Webley though the .45 ACP is easier to get brass and dies for.<\/p>\n

.308 to .32ACP and .32 S&W Long has been made in the recent past along with 7.62 x 39 to .32 ACP and .32 S&W Long. You can enjoy your large calibre rifles indoors in Gallery competitions with little recoil on cold winter nights.<\/p>\n

Be Aware, some rifles will quite simply not shoot well using Cartridge Calibre Converters and it is up to you to experiment with bullet weight and powder type\/charge to make these perform.<\/p>\n
