What’s your 150 load with Sta-ball and COAL?




P
I worked up to 48.5 grns with the 150 Fusion @2.85 COL, just to ballpark it, but I'm not done tinkering yet.

Here is the GRT output for 150 ELDX with 48.5 grns of SB 6.5 in a 20" barrel.
Pmax of 65,574
2703 MV

Yes, I wasn't going to get into that. Some individuals never check their throat depth as to when their bullet actually touches the lands. If they just seat their bullets long, when chambered the bullet gets shoved into the case causing a pressure increase. And they don't know why??

In my experience with Tikkas, most of the time a hand loader is constrained by magazine length, which is much shorter than distance to the lands.

I swapped the short action bolt stop on our 7mm-08s for long action and I can seat at the lands.

Roger that and I did the same for my 7-08 and 25-284.

We had a 162g hit 2780fps with reloader also but found mag primers are a big help, Decent accuracy (just over moa) and zero pressure signs or stress on the brass. We use multiple brands of brass also.

I tell people about the bullet and load every week up here in Alaska and people don't believe me. Hornady designed that 150g specifically for the 7-08 and 280ai crowd.
Bag flops everything other than big ass mean bears.
my 7SAUM is the ballistic twin of a 280AI, I might have to try some of these...

Finally got a chance to shoot my varget load. 22” proof tikka prefit, Alpha brass, Cci 200. Nothing to write home about on accuracy, likely just a seating depth issue but not sure what eld’s usually prefer on jump. Also lots of mirage today so I’m sure that didn’t help. Velocity deviation was low enough that I plan to continue exploring with it. No signs of excessive pressure.

That accuracy is plenty good for hunting IMO, and roughly laying the rounds over each target, I'd say you're looking at 1-1.25 MOA. From memory, those speeds sound about right for Varget. I'm averaging 2,525 MV from my 18" Tikka and SB 6.5.

No doubt. Those are all varying charge weights. I’d like to load up a bunch of the 40.7 load and see how they do over time

Sounds like a plan, and the good news is that all of them are delivering decent accuracy and now just need a little fine tuning. I have the 162 ELDX seated at 2.25 CBTO for comparison. Not sure if the ELDM ogive position is significanlty different.

I’ve got these at 2.1955 for a 22 thou jump

Every barrels different for sure, but I (so far) have seen more accurate results having the ELD-M’s jump a bit.
Was fooling around with N540 most recently since 6.5 StaBall and my barrel don’t like each other, and saw better accuracy/consistency jumping .080-.100 vs .020 and .050 (where I first started).
This was in a chopped M70 Ftwt so YMMV but as a data point anyway. I haven’t found the sweet spot yet with that rifle
