NEW Large Flash-Hole Reamer and Large-Caliber Neck-Turner from Sinclair Int'l

Sinclair Int’l has introduced two important new reloading products. Both are items that reloaders have requested for quite some time. Sinclair listened and now offers: 1) a precision large (.081″) flash hole reamer; and 2) a neck-turning tool for large cartridges such as the 50 BMG.

Large Flash-Hole Reamer
Sinclair has released a new, .081″-spec “outside-in” Flash Hole Reamer (item 07-3081) designed to designed to uniform standard flash holes to exactly .081 inch. This 3-piece tool features all stainless steel construction, a double-ended reamer guide for both large and small primer pockets, a knurled handle for easy turning, and a straight-fluted .081 inch reamer. With this tool you can remove burrs or obstructions in the flash hole and ensure that all your flash holes are the same size. NOTE — this tool works for both small primer pockets AND large primer pockets, for cartridges with .080″ nominal diameter flash holes. The new 07-3081 tool costs $37.50.

For quite some time, Sinclair Int’l has sold a similar device for small (PPC and BR-size) flash holes. Like the new 07-3081 unit for large flash holes, the 07-3000 Reamer for small flash holes works from the outside, so it can index off the primer pocket. It reams to .0625″, and also costs $37.50. The standard dimension for Lapua 220 Russian and 6mmBR flash holes is 1.5mm or .0590″. This tool will permit standard-size decapping rods with .0625″ tips to work without binding. However, note that both Forster and Redding normally supply .057″ decapping pins with their PPC and BR dies. So, it is NOT necessary to ream your Lapua BR/PPC flashholes, unless you prefer to do so for uniformity. It IS, however, a good idea to check BR/PPC flash holes for burrs before loading the first time.

NOTE: If you purchase either the 07-3081 or 07-3000 Sinclair Flash Hole Reamer tools, we recommend you mic the cutter tip before you process a bunch of cases. Sometimes a tip comes through that is oversize. This will ream the flash holes larger than you may intend.

Large Caliber (35-50) Neck Turning Tool
Jumbo rifle cartridges, such as the 408 Chey Tac and 50 BMG, are becoming more popular with precision shooters, and Sinclair’s customers have asked for a neck-turning tool which will handle the large calibers. Sinclair’s new NT-5000 Neck Turning Tool will work for cartridges from 35 caliber all the way up to 50 cal, including the 50 BMG. This new tool uses the same smooth, cutter adjustment system as Sinclair’s NT-1000 Neck Turner, but a special oversize case-holder is furnished with each NT-5000 tool. Special large-caliber Expander Dies, and large-caliber turning and expander mandrels are available individually or as part of a Large Caliber Neck Turning Tool Kit.
