Guys I've been doing a little work with H 1000 in my 65-06 with 147 and 140 ELDMs. Standard 6.5-06 A Square Match chambered 26" 1 in 8 twist Criterion barrel In a Mack Brothers Evo 2 long action. I like to do some load work in the summer so I don't get surprises when the temp rises. It's been 90-95 here with high coastal South Carolina humidity. The information in this post comes with the usual warning. These loads are safe in my rifle. They may not be safe in yours. Please start low and work up as 6.5-06 chambers tend to vary a lot.
With the 147s I started at 54.5 grains and went up to 58 grains. I used federal 210s and cci BR2s In Remington 30/06 brass And seated 3.388 or .012 off the lands. The first good node I hit was at 55-55.2 grains. Accuracy was good but stats were just ok. Velocity averaged 2890.
The second node I hit was at 56.5. Primers were still nice and round, bolt lift was easy. Primer pockets remained tight when I resized and inserted new primers. The stats on this charge weight were dead on single digits with many duplicate velocities. By far the most stable statistical node I have found with this barrel. BR 2s seemed to be slightly more accurate than the Fed. 210s for this load. Of course it worked out that way because I have many more 210s than BR2s. I plan to do more work with seating depth here. Velocity was 2936 average
I hit pressure signs at 57.5 and 58 grains with velocity up around the 3000 mark. This was pretty much right along with what Quickload gave me. Nothing catastrophic but sticky bolt lift and primers flattened. There was a good accuracy node at 58 but I won't be going anywhere near that high again. Primer pockets were toast.
I haven't done much with the 140s yet but it's worth mentioning that 56 grains is very consistent with a seating depth of 3.368. The lands with this bullet are at 3.373. I plan to do more work here with seating depth as accuracy wasn't great. Velocity was a consistent 2945. No signs whatsoever of pressure. I suspect some of the issues with accuracy are me. I never shoot as well when it's hot and my glasses are fogging. I have been shooting H4831sc and pretty much topped out at 2890 with 147s. I decided to try H1000 in the hopes of getting that speed or a little more while getting a bit less pressure. It appears that may work out.
As I do more testing and close in on a load I'll try to update as 6.5-06 info tends to be a little bit sparse. I'll do a good bit more testing as it cools off. I'd like to try some different brass possibly and have even given some thought to trying some Peterson 270 brass. I generally used once fired cases. I anneal and then full length size. Then I neck size with a Lee collet just to make sure neck tension remains consistent. Once my cases are fire formed I just use the collet and bump shoulders with a body die as needed. I'm hoping the 147s work out well. The BC is nice and it stays Nice and flat at distance. I've shot around 200 of them so far and fortunately have not had any disintegrate on the way to the target as some folks had a few years back.
