    Anyone using the new Lapua 6.5 Creedmoor brass???

    As usual Lapua will have thicker case walls then hornady or Nosler resulting in reduced case volume, adding the same amount of powder in both will give higher pressure in the Lapua cases. Also freebore and bullet seating depth can change pressure and powder capacity some on its own. So if your...

    Powderfunnel with Drop Tube Help Resolve this Issue?

    Not advocating brand loyalty, I use them because they have a few advantages some of the cheaper ones don't from my experience, they all do work after all it is a simple funnel. And yes the funnels will more easily make the powder swirl into the case if they are slightly tilted, a straight drop...

    Powderfunnel with Drop Tube Help Resolve this Issue?

    A drop tube will help you quite a bit, have not really taken exact measurements though. As a example my 308 with virgin Lapua brass, TTSX 150 gr, COAL 2.8776,.001 neck tension, with N150 using a Satern funnel i ran 46,5 grains, using a 10" drop tube from 21st i run 47,5 grains, while seating...

    Gunsmithing Barrel nut setup on FN/Win Mod 70 ????

    It's possible to fit a barrel nut to a M 70, pretty common on M98s witch has the same type of extractor. Can order one for 150 dollars and have it delivered within a week for myself. Will of course still need some machining to fit. Not saying it's the best solution available, a WIN M70 with a...

    Gunsmithing 6.5WSM

    Honestly the cases are very similar, just 5-6 grains of difference in powder, same as the difference between a 7 saum and wsm pretty much. The SAUM cases are more well suited to run in a SA, and have a bit longer neck. The 270 and 300 wsm cases have slightly longer neck and less internal volume...

    There is a modification or two you can do to the classic style AI bipods, you can get a friction lock for them to reduce the slop/cant in the head of the bipod witch is really helpful feature with this model. And you can get a pair of big rubber feet for them. The friction lock is sold by...

    Need case length opinions

    Okay, your shooting a caliber with a notoriously short neck, using heavy bullets and slow burning powder. Forget about reloading manuals and recommended trim lengths, 99,9% chance it will not match your rifle any way. Remember that recommended trim length might or might not have been optimal...

    Gunsmithing T3 replacement trigger

    The TRG trigger fits as mentioned an is probably the best choice if your not looking for a bench rifle. Would be my first choice for a general purpose rifle, and is a very nice 2 stage trigger that is reliable. THe old model CG jackson 21 fits the T3 and are excellent 2 stage triggers,but hard...

ANd yes STM cleaning can certainly peen your case mouths and cause similar results, fill it well up with water and run it a shorter time, should help. STill want to chamfer and...

    Reloading .300 win mag., is this the correct redding die set?

    If the money does not matter too much, i would go with the competition neck die set. It does all you need as it consists of the comp bullet seater, body die and comp neck die. You have a bit more adjustability with the comp set, and the ability to partially neck size the cases. The type S FL...
