Brotherhood! Hey guys, I feel like I know you all from reading 460 pages now of the STW thread! This is my second post - my first was in the STW reloading thread (no reply so pretty much re-posting here).
I've got a decent Rem 700 STW (one of the newer SPS's) with a bell and Carlson stock on it from Redhawk. It shoots Nosler Custom 160 gr. Accubonds really-really good, but I have a buddy that reloads and we're in process of working up some loads for the 168 grain Accubond LR's. This rifle was supposed to be a project that I planned to re-barrel, but apparently I got lucky.
This is my first time working up a load for any rifle so any suggestions in developing loads and laddering up would be appreciated. The starting point, powder, primer, etc... all came from knowledge gathered here.
For the first go round he loaded me up a 15 shells in groups of 3 at various charges of H1000 with Fed 215 primers in Nosler Brass from 74 grains up to 78 all at what I think was the same length as the stock Nosler Custom 160AB's that shot very well (I think he noted it as 3.651").
I got a good tight group 0.466" center to center at 75 grains and things were coming together again at 78 grains with a decent group a little over 1" but very little vertical spread (maybe 3/8"). It was windy L-R 10 - 15mph. I had no pressure signs at 78. Where do y'all expect the top end charge to be on this bullet with H1000? We'll work up gradually but don't want to miss a good load by stopping too soon and also don't want to load up a bunch of stuff that's too hot and will have to be pulled.
My chrono is down, but will be back in business for my next session so I can report back with velocity info next time.
Not sure if we should now go back to 75 & 78 grains and vary powder in 0.1 or 0.2 grain increments or if I should vary seating depth with the best load we had - then vary powder after seating depth.
Or... should I just load up about 9 of those 75 grain loads and see if it will consistently shoot like that? I can't imagine a factory STW can really shoot much better than 1/2 MOA, I do trust this rifle though - I have shot several sub 1/2 MOA groups with this thing at extended ranges from 250 - 780 yards with the nosler customs and have shot it out beyond 1000 yards with deadly accuracy. I painstakingly broke in the barrel and it seems to have paid off.
Thanks in advance and thanks for all the great info. Like I said - I have read the thread thru 460 pages now and just finished reading the 32 pages of the reloading thread. I will burn through the last 90 pages so I'll be current ASAP. Looking forward to being part of the crew here!
