Anyone loaded up their 7 SAUM using H1000 and a 168 Berger VLD, or any other bullet for that matter?
I tried some H1000 in my XP-100 even though I've already got a couple loads that are good to go.
What surprised me was the velocity.
Now, my chrono may be lying to me, as it's a low cost Shooting Chrony, but on same day shooting comparing it to H4831sc, it showed a considerable increase in velocity over H4831sc.
I still have a bit of work to do if I choose to use H1000, as I did t quite get the accuracy I was hoping for (still sub MOA, with about 2/3rds MOA observed with the best load).
I hate to even say what my chrono registered because I don't want a bunch of flack over the numbers, but it suffice it to say, it was impressive over H4831sc.
The F class rifle shooters seem to have locked onto this H1000 as the powder of choice for the 7 SAUM which is what prompted me to try it.
I'd love to hear other's experiences with it as well.
I'm not running H1000 or the 4831, but I've seen very similar results running Reloder 22 in my 6.5x55 AI XP. Same for my non-designated Remington 700 in .243 Winchester Match. I got better velocities with the heavy Magnum powder over 4350.
I am also running rel 22 in my 7 saum with 140 NBT's. Excellent accuracy but have not checked velocity yet.
I have always used H-1000 with my 7 SAUM and 162 A-Max's.
This combo has a great record for me and Erik.
I also use H-1000 in my 7 LRM with 180's.
Also use H-1000 with my 7WSM and 180 grain JLK's
All three of these rigs have earned their share of bragging rights

Thanks for the replies.
For those of you using H1000 in the 7 SAUM, what would be the ball park powder charge weight range would be for 168 gr bullets?
I started at 64.0 gr and worked up.
Load data for the Berger 168 and H1000 is pretty scarce.
However, if my chrono data is actually accurate, it makes me want to try the Berger 180 VLD.
Give me the total overall loaded cartridge length
with the bullet you want to use,
water capacity of your case,
and I'll see what QL spits out.

My Coal is right at 3.024" (cbto length of 2.333")
Bullet of course is the Berger 168 VLD hunting version.
17.5" bbl. I have t actually measured H2O capacity of my cases (rarely ever do). I've seen data at 73.4 gr but have no idea if that is representative of my cases.
I started at 64.0 gr and went to 67.0 gr H1000. I saw just a hint of pressure at this 67.0 gr.
I measured three fired cases of the 67.0 gr load.
Water capacity to the mouth of the case is 74.4 grains average for the three cases.
I shot both 168 Bergers and Accubond LR's this weekend in my 7 Saum. I also tried 160 Accubonds. Using both H1000 and IMR4831. Both with starting loads. 64gr. of the H1000 and I believe 56.0 with the IMR4831. My best groups at 100 yds. Was with the 160's followed by the 168 Berger's using the 4831. In fact all of my best groups, with the three bullets were with the IMR. I haven't given up on the H-1000 yet though. Might just be a COAL thing.
What were your findings?
Arrowflinger, It's been a while since I shot the Berger 168 / H1000 combination. I don't have my load data here with me, but I do recall my best load was the starting charge weight of I think 64.0 grains. Velocity was around 2750 fps.
I recall the 67.0 gr H1000 Berger 168 VLDH load producing around 2850 FPS but accuracy wasn't what I wanted at that charge weight. I have not got around to working with it anymore. I plan to sometime soon.
I have a load that shoots the Berger 168 VLDH bullet very well using H4831sc (normally between 0.2-0.5 MOA) at 2700 FPS. I haven't used the IMR version, nor do I plan to at this time.
I have shot a limited amount using the Nosler ABLR, and accuracy hasn't been consistant, nor as good as the Berger 168 VLD or the Hornady 162 ELD-X bullets.
I did some load work using H1000 and the Hornady 162 ELD-X bullet. It shot very well, and I plan to run that load for now.
