Well got out tonight other than a bad wind call on my part dead on at 600 and 930.
I killed them rocks real good now a quick clean and final sight in and sheep hunting is on in 14 days. I can't wait to rip something other than steel and rocks !!!!

Good luck and be sure to let us know how the hunt went.

He guys I'm finally getting some range time in. I'm a novice reloader so if you have any recommendations please feel free to make suggestions. Seems like I'm running a lot less overall length then I thought. Best accuracy so far was with 61gr varget and 250 Berger eh. 23 in proof carbon barrel. Got a slight ejector mark at 61 so I quit there. Might back it off a half a grain.

That's close to what I ended up with with 250 looks like some consistant loads you have going very nice. The 230s are shooting bug holes for me at 2885 and I dial less and loose very little ft/lbs at 1000
Very happy with 230s
I want to try the 270s next.

With the standard reamer it is a fair amount shorter than what the other guys are running at.

Anyone shooting the 213 or 235 Hammers with your 338 SS? Where are u starting with Varget with these loads?

Thanks!

 

[ramrod79]

there was one fella shooting 235s his load was 66 gr Varget I believe.
If you go to Sherman wild cats check out the 338 SS there is load data complied there for you to check out.
Any of my loads I fire formed at 56 gr of Varget. My 250 Berger load I started at 57gr went to pressure. My 230 load I started at 58 worked up.
I believe Steve from Hammer did load work with the 338 SS so he may have more info for you as well.

What sizer die and brass are you using?

I have Whidden dies and having neck tension problems on once fired brass.

Thanks

 

[ramrod79]

I'm using ADG brass I anneal every second firing and I also annealed right after fire forming as well I'm using 262 bushing. I am also using Whidden but I'm gonna try the Forster I think.
What kind of neck tension issues?

 

[ramrod79]

I also use a Hornady bump gauge not the whidden it makes a world of difference.
