I shoot 180 Bergers out of my 28" 1x9 twist 7stw at .020 or .030 jump I believe. Used Retumbo! I'd have to dig up my data to be sure on the exact distance off the lands. I started with what ever would fit in my magazine and went from there. All said and done I can cover 5 shots with a nickel. I am running them a little slow for a STW, around 2900 fps. However the muley I dropped at 395yds didn't know how fast the 180s were going. Very accurate recipe. Just tweak it to work for you.I am going to try out this bullet in my 7mm Rem Mag with rome RL23 and I'm curious how far of the lands is best for it before I load up some rounds
TIA and stay safe
Looks like ZR600 has it correct. My memory was a little fuzzy, think I had another seating depth test in my head from someone else as well.I did the Berger seating depth test. .010, .050, .090, .130 off the lands. .090 was the best group.
7RM was .090 off. I followed berger seating depth tutorial. NOW, after watching Eric Cortina video on page 1 of this thread, I am wondering how many nodes I completely skipped over at .090 off! Reloading is the gift that keeps on updating and throwing curveballs.Was yours (.090) out of a 7STW? My c.o.a.l. is 3.195 and with a Hornady comparator is 2.958 ojive and my mag well is 3.680. I'll keep looking for the jump amount. I found some old data I shot showing I started at .030, .050, .090 and went all the way up to .130. I believe I was around the .040-.050 . Now I'm on a mission to find my info.
I was thinking the same thing but Berger claims that the Bands for the nodes are .030” to .040” wide on their VLD’sI can assure you when you do as big as jumps as Berger recommends your missing nodes. I do course at .010 at a time, fine .005 but each to his own.
Search Alex Wheelers method on this post.Fairly new to reloading. I am a machinist. Interesting thread. I have not paid attention to the distance to the barrel lands. How is this distance checked? Thanks in advance.
