For break in I usually just throw in 30 grains of Varget for the first 200 rounds. Then load development. I usually land between 32.2-32.6 for a speed of 2940-2960. If you want to run slower like a lot have been doing lately I’d shoot for 31.0 and work up.
Most I’ve read start around 33 gr with RL16. You’ll need a long drop tube as you approach 34 grains coz that brass has less capacity and RL16 is bulky.
Thanks. I will weigh some of the Dasher brass, but Peterson 6.5 Creed brass is heavier than Lapua, so if it holds true for the Dasher brass, it will have less capacity than Lapua. I will probably start at 30 to see where I am at.
The barrels a little light with and m24 and if you are gonna run lapua brass (no turn) you need two tighten that neck up to .272
Weighed some fired Lapua Dasher brass with the spent primer and new Peterson Dasher brass without any primer. The Peterson is 13-14 heavier than the Lapua. I loaded 10 each with 29, 29.5, and 30.0 of Varget under 107s .030 off the lands. Hopefully I can get some time to shoot soon.
Rifle 1 is Lapua brass and Rifle 2 Alpha?
No both of mine were Lapua...Rifle 1 is a buddy who uses my equipment to load and Rifle 2 is mine. Both of us had SAC build a barreled action and use all the same components in hopes of mirroring loads.
I am shooting 32.1 -32.6 again this weekend in .1 increments (again in fresh alpha brass) with BR-7.5s to confirm that node.
I generally don’t do any load development or draw any conclusions until I have at least 100-150 rounds through my barrel. I just load a mild load and shoot club matches or practice.
Is there a specific reason to do that? Like in order to form the brass exact to the chamber or something? There is a flatter node that is milder I could try for a while at 31.1 grains, it hit 2836, 2838 and 3836 again in one tenth increments.
If you’re looking for velocity nodes on a barrel, most barrels will increase in velocity anywhere from 50-100 fps after the first 100-200 rounds, so until that barrel settles in then your node isn’t a node because it will be changing constantly.
Well why do you assume you hit pressure too early?
They were all .070"+ jump, the 109's and 110's had a slightly (.005"-.010") longer jump as I have found the 108's and 109's shoot great with a longer leap out of my barrels.
Don't get me wrong that I agree with you, just still confused by the weird performance between the three bullets. I am not expecting them all to shoot the same, it is just a little strange that the 109's and 110's shot basically the same numbers, but the 108's were so different. If anything, I would expect the 108's to shoot a little slower than the others due to the long bearing surface and tangent ogive!
30.5 - 32.0 gr Varget. Started hitting pressure at the 32 gr node, but yes, the bullets are jammed pretty far back into the case to get that kind of jump. I will be tinkering with a throat reamer soon to push that out a little further!
I'm looking at a Proof pre-fit 26" Dasher later this year....if anyone here has run StaBall in the Proof I'd love to year your results. Thanks
I've heard Staball carbon fouls pretty bad in other cartridges; any reports for the Dasher?
I use it with my Dasher and 223 rem and there is definitely more carbon than some powder but I find it just like than Varget . Nothing that bad
I've run about 3k rounds of it in 6.5 Creedmoor no carbon fouling here.
Great like that thanks for the info.
I have used 500 of the OCD alpha brass for about 3 firings. Really really good stuff. No special reamer required. The neck thickness is the same as Lapua. The overall length was pretty much exactly the same as fireformed Lapua brass. I think mine was 1.540". No issues using it with the exact same load as my hydroformed and fireformed Lapua brass. My velocity was within 10 FPS with the same load. No difference in precision that I can tell.
Alpha has them in stock right now so I ordered some. I wonder how the longevity will be vs lapua.
What die are you using to size your brass?
I use a Forester full length non bushing die. I had them home the neck to .2660". Works perfect.
Free bore?
No I’m asking what Freebore everyone is using in their chambers for the 110 Atips
