[QUOTE="freddiej, post: 2032585, member: 26227"] I have questions due to the fact I was a long range target shooter back in the early 1990's and this always came up. I had the same frustrations with my 300 Win Mag back in 1,000 competition. Have you ever thought of measureint eh the individual lengths of your slugs? if not, try it and see how much they vary in your box of 100. Sierra, and yes I am going to name names on this, used to use 3 to 5 different sets of dies for their match slugs in each box. this caused varying lengths from the 0.300" diameter to the tip and to the rear. this caused all wholly hell with certain guys I knew. now if the projos in question are made like the old Sierra slugs are then I would say that your frustration is not the jig but the slugs. I have used this gauge for many years and found it to be within 0.0005 to 0.0015" each time with the same slug. I recently used 4 slugs to get an aggregate with the 500 piece box I have of HPBT Hornady slugs. they came out as I expected.. 0.022" meaning they were a mix of several different sets of swaging dies in the same box. not a big deal with hunting slugs. now I did that with some other slug brands, Barnes, Nosler, and Speer. Speer was average at 0.019" Nosler was good at 0.009" and Barnes was super at 0.004". I also measured the over all length of the slugs themselves and found about the same variation in their length as overall cartridge length.
