Well, it just so happens my "pet" load for my 26" 6.5cm Savage with 147gr ELD-M is 43.1gr of StaBall 6.5 at 2730 fps.
This is the load I used last year in a long range precision rifle course with Frank and Marc and was getting centerline hits at 1240 yds and consistent 1st round hits at distances from 400 to 1000 yds.
With the 147s, H4350 wasn't quite as accurate as StaBall but this year I used 140gr ELD-Ms with 42.4gr of H4350 at 2840 fps and got the same results.

I have lots of pet loads for a 6.5, several of which worked great in my MPA in 6.5 (since rebarreled to 6GT). Problem is what works great for me may be terrrible in your rifle. Further, MPA builds enough rifles and barrels that they do replace reamers which I feel is a good thing. Probably the reamer in my 2022 barrel has likely been replaced many times since. And we are not even getting into the tools used to drill and rifle barrels.

Point, don’t use other people’s loads, get some good reloading manuals and have some fun finding out what YOUR barrel’s pet loads are.

Just trying to get a good baseline. Ive seen that the max charges run from 40.3 to 41.8 max depending on which manual you look at. And some guys are running much hotter than that. I just seem to have a problem finding a CONSISTENT load. 38.8 worked just fine (around half moa) but i get weird changes in group size and spikes in es/sd from time to time

Just for fun since I tried looking it up and didn’t see any data on if mixing lots of Lapua Brass matters. I have 400 Lapua srp, 2 different lots that has all been fireformed and was trying to determine if it was worth the pain of keeping it separated. Lot 1 is about .5gr lighter than the lot 2 brass. So I took 5 of each and loaded them up with the exact same load and round robin’d them. Not a huge sample size, was just curious.
40.0gr H4350
140gr eld-m
CCI 450

Group size was slightly better on Lot 2. I will probably end up mixing them after the next firing.

I just made a thread about this maybe a month ago. I didn't count, but I think I had about an even split on replies.

I would say try 20 shot groups with each to determine.

Dang I’ll have to look for that. That is around the time I actually did this, after I actually searched. Probably depends on the specific lots too.

I’m fine with mixing these numbers, for what I need it will work just fine. This was just the first load I picked after a POI ladder when I got the barrel. I shot it for 4 local 1 days so it has 400 down it now and have a node that I think is at ~2810fps so going to try that compared to the 2695 I am getting here and try a few seat depths quick.
