ARC Ballistics Products

All British manufactured 3-way trimmer (trims chamfers and Deburs) will trim multiply cartridges of the same calibre (based on case family) I.e .308 case family, .223 case family, Magnum case etc, the trimmer can go to as large as .50BMG and will cater for ELR cartridges specifically (.338/.33XC/.375 CT .408 CT 416 Barret etc)
(Large cal cutter/mandrel required for .anything over .33 cal to .50cal) Trimmer indexes off the shoulder Datum and will cater for neck turned cases and no turn (please specify when ordering)

Additionally and most importantly the cutter DOES NOT NEED ADJUSTING, unlike most 3-way trimmers this saves loads of time and messing around and is super simple to swap cartridges and calibre.
The trimmer is made by ARC ballistics in the UK and is constructed of top quality materials to exact tolerances, it will repeatedly trim/chamfer/debur to 1 thou or under if required.

Expander dies and Mandrels
To Compliment the trimmer ARC is manufacturing superb quality expander die sets and De-capping dies, these have been designed with solid one-piece de-capping stems (no screw-in pins that bend and break) this is especially important when de-capping Large ELR cartridges.
The expander is designed to expand brass smoothly and efficiently and is designed to complement the trimmer, available in standard calibres .22,6.5,.308 etc and for the ELR cartridges the Large expander will handle .338 to .50cal.

ARC Primer Pocket uniformer:
Finally to compliment the above ARC has designed and made an adjustable primer pocket Uniformer, again all British manufacture and made with top quality components and to a precise tolerance.
(note primer pocket unforming should be undertaken with care and to SAAMI guidelines, we recommend that pockets are measured before adjusting the tool past SAAMI specifications)
