Mackgee, I've gotta jump in here. I just got a new 7 STW built by Allan Rovig with McWhorter custom. Stiller action same shadow grass camo McMillan Rem hunter stock, in a lefty. Got a Vortex PST 6-24x50. You'r gun looks awesome. I chose a little bit cheaper option than you.
Got the gun in yesterday, with 40 rnds 180 gr VLD, N570, which shipped separately, and apparently UPS ran over the ammo with something, so now we have 40 rare STW cases destroyed. Allan's sending 2 more boxes tomorrow, and he's about out of cases. Anyway I've seen some talk of necking down 8mm Mag brass down to 7 STW. I bought 50 rnds of Nosler 8mm mag brass, and may buy more once I figure out if this is gonna work for me. I'm not overly experienced in handloading. I have necked it down with full length RCBS die, and came out good, concentric, but with a donut at the neck shoulder junction. I suppose I can fire form, as I dont think the donut will do much for accuracy. I see guy talking about necking down 375 HH brass. If you can neck down 375, can you also neck down 300 HH brass. Right now I can get Nosler 8mm Mag, and Norma 300 HH.
What do you guy's suggest? Aplogies if I've not read all post's on this thread and the asnswer is here.
Been loading for 300 RUM for about a year, and I broke down and went full out MCWhorter custom in 7 STW. At this point I dont know when 7 STW brass will be available, but I dont have time to wait. I have plenty 215's, and N570, but short on brass.
At this point the Nosler 8 mag brass seems to neck down fine, and its available. Would it be good to go ahead and pick up more?
Oh, and I'm brand new to the STW brotherhood. Have yet to fire a round yet. Hopefully will be firing next week.
