6.5X55 loading for modern action IMR7828 - H4831SC
- Thread starter kilohertz
- Start date
Thanks again for the replies.
I have finished the stock work and am back to reloading. I trimmed and measured all the R-P brass this morning, they are ready to reload, however I do have some brand new GRAF brass and some once fired Norma, but only enough Norma for maybe 20 rounds. I'm off to the gun shop to pickup some RL-22 and see what they have for different dies for the 6.5X55.
Opinions on the GRAF brass?
I'll check in later before I start loading.
Cheers

I had a swede a number of years ago and I used Reloder 22 and 4831sc, I chatted with John Barsness on the 24hourcampfire and on his advice I used my chronograph to load up to 260 remington velocities with both powders.
I made it to the range today to continue testing various powders and loads, it was a good day of shooting but nothing spectacular in the results.
IMR7828 I took up to 50g but stayed with the CCI200 for now to keep consistent with previous loads. Made it to 2774fps and 2 touching with 1 off by about 1.5" at 50g. All loads of 7828 were mid 30s ES and mid teens SD, nothing sub MOA.
H4831SC continued up to 49g and again maxed at 2774fps. In this range of 48-49g groups opened up to 1.5-2MOA, yuck. There was a sweet spot at 48.5g with an ES of 10 and SD5 but group was 1.5".
RL-22 loaded 46-48g and max 2733fps. Sweet spot at 46.5 with 3 shots identical fps, amazing and 47 with ES6 SD3, also very good. Grouping was better with RL-22 with 2 groups with 2 nearly touching but always 1 flyer about 1.5" away, don't know why.
Today's loads were all in properly sized and bumped .002" R-P brass, primer pockets cleaned, all cases trimmed and weighed, pretty much everything I could do to make the rounds accurate, rifle is now bedded and barrel floated.....
I suppose the next thing to try is seating depth and different brass. I seated all loads so far at 3.15".
Suggestions, thoughts etc. always welcome. I know this is just fine for hunting and in all of the testing there are good hunting loads, I'm just on a mission to get 3 nice shots sub MOA.
Cheers
PS a surprise today was the last rifle I shot, my trusty old Husky 1640 mountain rifle in 30-06 with a 20" barrel, the last 3 shots were with 56g of IMR4350 and 178g ELDX and shot all just under 2600fps and 1/2 MOA with 2 touching, not bad and a good way to end the days shooting. And this was with unweighed, untrimmed, nothing special just FLS and load with the Dillon press. Too funny.

The only time that I'm ever concerned with my Swedes is when I chronograph the loads that have proven to work in the field! I used Reloader 22 for years but was never really satisfied. I switched to Lapua brass long ago and it is worth the cost. I've had good accuracy with both IMR and H4831 sc however many suggest H4350 for the 125-130 grain Noslers I prefer so I should try some. I have a bunch of 129 Hornadys that I shoot for practice. I haven't tried Reloader 26 or other newer powders however they seem to offer promise. Truth be told, if I get good accuracy at around 2800 fps with a 125 or 130 grain partition or accubond then what more is really required from this sweet heart of a round? These loads are effective and easy on the rifle, brass, and shooter.
