10-gauge "double barrel" case timmer

[Frank Srebro]

I’d like to share some pics of my “double barrel” case trimmer for 2-7/8” Short Tens. Trimmer was made from the chamber end of an old 10-gauge barrel. In the past I shortened 3-1/2” 10-gauge hulls by holding them on a mandrel and spinning against a sharp utility knife blade that indexed from the base wad. That worked OK but it seems the base wads aren’t that uniform in height and sometimes the cutting blade runs off. Thus the cut 2-7/8” hulls varied a little more in length than I liked. This new trimmer indexes the 2.875" cut from the rim of the hull. I’m sure someone will ask me what this barrel came off. Answer is: I don’t know, the barrel legend is hard to read. I bought the barrel for 15 bucks at the Allentown gun show two weeks ago, Most of the pics here are self explanatory.

Filed smooth, before stub was set up on the mill and machined to exact length

Barrel stub held in the bench vice and new Remington 3-1/2” cases in place. These are the olive green 3-1/2" 10-gauge hulls sold by Precision Reloading.

That’s a craft saw with an ultra fine tooth blade.

Cut is complete and hulls were finished-trimmed with a long utility knife blade.

Ten cases took about 4 minutes to make. Cases vary only about .003" in length.

Getting ready for the Bo-Whoop Long Range shoot at the Northeast SxS next weekend. That's a MEC 10-gauge Sizemaster with a so called short kit.

These older Remington Express hulls are marked 2's but are now loaded with 7-1/2's. Same shot size in the olive-green current Remington hulls. Both types were cut to 2-7/8" and now have 1-1/4 ounce of shot in Rem SP-10 wads, Rem 57 and STS primers respectively, and pushed by a fair charge of IMR SR-7625 powder. These are as yet unfired hulls. As one of my shooting buds would say: "nice crimps".
