The Borden Bigfoot action fits an over sized Rem 700 long inletted stock.
The action is 1.4 inches in diameter and has 1 1/8 x 18 TPI thread tenon
.750 diameter bolt that has 1.063 diameter lugs and .475 high lugs.
It utilizes either the sako style or internal hook extractor (can be ordered either way for the repeater version-the single shot version uses sako style and has coned bolt nose).
The scope rail is held on using 8×40 screws in holes that are thread milled and the rail is located on the action with 2 1/8 inch dowel pins.
The magazine well is cut to use the wyatt CFE12.
This is the straightest and best designed actions Ive seen for the big Lapua and Norma cartridges.
