    6mm ARC (Bolt Action)

    The barrel is a Shilen Select Ratchet, finished at 24" . Generally when shooting, DA is usually between 6000 and 9500

    6mm ARC (Bolt Action)

    Amazing the differences in cambering , and how it can shape the load possibilities of the same cartridge. I'm slightly tight on SAAMMI print . 28 grains of Varget in summer put me into the high 2800s with105 hybrid at .020 off the lands. Sticky lift and loose primers . The loading hammered in...

    6mm ARC Bolt Gun Loadings

    ARC Nucleus v2 here. With ARC and Zermatt It is quite nice having the ability to change bolt heads, also have the .384 and .473 for future caliber considerations

    6mm ARC Bolt Gun Loadings

    In my limited experiences , 30-50 fps gain in speed should be expected. Possibly / probably more as I've experienced. This particular barrel is a Shilen select ratchet rifling , finished at 24", mounted to an ARC Nucleus V2 via a barrel nut system. I used the Savage small shank nutted system...

    6mm ARC Bolt Gun Loadings

    Been a while since I've updated this thread. Local rimfire season has came to an end, with the cold weather setting in found some centerfire time. A while back I picked up 1000 inexpensive 107 SMK seconds , to use in the semiauto 6 ARC for distance plinking . The base to ogive on these were all...

    6mm ARC Bolt Gun Loadings

    UPDATE Unfortunately, the 28.9 Varget load with the Berger 108s sped up on me considerably. I don't know if it is the barrel still breaking in, or some other issue with my load procedure and / or barrel cleaning. Was seeing 2900+, and it started to blow up the group a bit. It is throwing a shot...

    Reloading 9mm problem?

    Tightgroup is pretty dirty nasty stuff, and burns hot. Makes it easy to differentiate your brass from others, as it will turn it colors. I agree, that load sounds fast at a 146 power factor and you should double check your crono readings. I load and shoot a shit ton of 147s in my hot rod pistols...

    Pushed shoulder back to far advice

    This happens occasionally, and at only .006 is a non issue with the load safety. It can however effect accuracy slightly, as the ojive to lands ( aka jump) will change the amount of difference in shoulder bump. I.E. your normally bumping shoulders .002, and these are at .006 so you have .004...

    6mm ARC Bolt Gun Loadings

    Loaded up a two sets of ten revisiting the previous post's Berger / Varget combo at 27.9, and a tenth over at 28. Printed some nice groups, both charge weights showing same POI, I'll call this GTG. Think I'm at my practical limit with a bipod and bag anyways. Going to continue working on the...

    6mm ARC Bolt Gun Loadings

    Ran a couple more ladders yesterday, the first was with Varget and 108 Bergers and the second was with 108 elds and RL15. Things of note, the barrel picked up on average ~50 to 60 fps after a thorough cleaning at the 75 round mark. I pulled a couple patches during the first 10 rounds of barrel...

    6mm ARC Bolt Gun Loadings

    Worked up some loads checking out the 27 grain window, results were pretty favorable. Tried a couple groups neck sizing only top row, and second sets with a light FL and .002 shoulder bump middle row, and a set with .005 bump. Seems as if it liked a little shoulder set back. Going to tweak the...

    6mm ARC Bolt Gun Loadings

    Thanks for the input, opposite paths ending in the same place. I've used the IMR 4895 in the past but not H. Also on hand, and in the mix I plan on working with RE15, Shootersworld Precision, and Leverevolution. Lever's been pretty good in the semi, just not a big fan of ball powder. Here is...

    6mm ARC Bolt Gun Loadings

    I have finished a 6mm ARC bolt action, and there's not a whole lot of data out. . Been fooling with the 6 arc in first a 18 inch and then a 22 in semi for the last year, so I have some baseline and experience with loading the cartridge. Did a shake down was with 10 rounds factory 108 eldm, and...
