Inset-Bar conversion examples

Stronger and more durable than Cramer-style conversions and just as fast, if not faster! Nearly any mold of any caliber or number of cavities can be converted to hollow point using this system. Including single and double-cavity Lyman, RCBS and other similar bullet molds. Inset-Bar assemblies are fitted to slide freely.

H&G 4 cavity molds can have up to 3 cavities converted with my Inset-Bar system. LBT and similar molds can have any and all cavities converted with this system.

Inset Bar may not fit longer rifle cavities on some smaller molds.

Additional Inset-Bar Assemblies

Inset-Bar Extractor linkage eases casting by pulling the inset-bar with hollow point pins out of the cavities as the handles are opened.

For Magma Master Caster ( single mold ) or the Bullet Master ( 8 mold ) casting machines. Inset bar hollow point conversions are complete with special extractor link, inset bar geometry and sliding pin clearances for Magma machine casting molds.

Note: Pin size and shape have some limitations to ensure proper bullet release when machine casting. The Magma Master Caster and the Magma Bullet Master use different extractor links, be sure to let me know which machine you are using. Linkage adjustment may be required for proper operation due to differences in individual machines. Adjustment must allow some minor remaining movement when the arms are fully open. Mold setup person should contact Erik for instructions. Machine conversions only available for Magma blocks or Accurate Molds Magma-type blocks.
