Re: 6.5WSM

from a laymans standpoint i think most would be happy just knowing what will
work safely in their gun. fortunitly my gun has a savage action so changing bolt heads due to scarring from blown primers is no big deal.
i highly advise the use of norma brass for this reason as opposed to winchester. realize the pressure is still there but the brass handles it better.
to me a sticky bolt is the gun telling me when its had enough. i allways start
my testing with wildcat cartridges by loading 1 each for each combination i
want to use. then increase in 1 grain increments till i come to the stop sign.
since i want max performance i work backwards from there with my load testing. im currently using 64 gr h1000 with a 140. the gun works very well and is accurate with that load. i havent tried it on 90 deg days however.
nor do i intend doing so as this is strictly a hunting gun.
as for the old powders like h870, the only thing good about them is that they were available when nothing else was.

Re: 6.5WSM

I found LEE 6.5X.300 WSM Dies on ebay, they are full length size dies.
I am using the Micrometer Redding 6.5 bullet seater, with neck bushings to
neck size only.
We are getting 3250 out of 142 SMK and 140 Berger Hybrids with 63.5gr H1000.
3500 from 107's.
ALWAYS WORK UP SLOW!!!! WATCH FOR PRESSURE!
NORMA brass is our choice, FED match primers
I seat .010 off the LANS, you can get too much pressure seated too far in or off!

Re: 6.5WSM

H-1000 is too fast to fill the case, yes you can get pressure but you will use the entire .270 WSM case with VV N-570, Retumbo and Magnum and get the same or more velocity with less repeat less pressure. Check Quickload if you don't believe me.

Re: 6.5WSM

My reamer is .297. I have never felt the need to turn necks. I have Norma and Nosler labeled brass. I have used a few Winchester cases with similar results.

I have a Wilson neck size die and I use a .295 bushing. I have retired only a few cases, even with two nitrocarburized barrels but most are the result of overloads and loose primer pockets. Two split necks so far.

I also have a Lee Collet die (at one time a regular stock item, 6.5-300 WSM is the label) which sits. I use a Redding .270 WSM full length die bushing die to make cases into 6.5 size. I have a Wilson seating die that was made from my reamer. Make sure you get the 6.5 VLD die stems. Test your seating die stem by turning it upside down and placing a bullet in it. A VLD stem will support the bullet but in most dies the bullet will bottom out and be seated by pressure on the metplat.
