Mandrel will be the next step and I'll check run out again, first I'll check the concentricity of the case neck thickness.

Yes, barely can hear it, I backed off the bushing by a quarter turn and the bushing numbers are facing down. The fired case measures .341 on the neck, and the bushing is a .336, that gives me .005" size down, and its .338 loaded. I could try a .337 bushing if I have one , but the .307 mandrel...

Keep us posted on your results with the 550 in the .308, I'm curious. 550 is an high energy powder.

I recall using N165 for my 7 Mag a long time ago, it was the only VV powder I used. I have read that VV has gained popularity these days. I am curious on what VV powders are liked for the .308 and 6mm BR. I use Varget currently for those two calibers. I read that N140, N540 and N550 is great...

Starline is good stuff, I use Starline for my pistol brass.

Haven't used the mandrel to expand it yet, I was testing the runout after sizing.

I use the Sinclair expanding mandrels.

No, sorry for not being clear in the first place, I meant just the sized case neck on a RCBS CaseMaster to check neck runout, without the bullet seated in it. As for the expander, I never liked them for the reason you gave, I removed them all from my dies, I use a Sinclair carbide expanding...

I use Redding full length non bushing and bushing dies along with competition seating dies on a Redding Boss press. I use the trusty Hornady lock rings to secure my dies. I have no issues with accuracy with my rifles, but I have seen some runout of .003" after using the bushing sizing die which...

Yes, those 4 boxes are the same lot. Pretty much confident out to 300-400 yards depending on the accuracy of the tune.

Wanted to try a new tune for the .308 GAP with 26 inch barrel, I'm bored and currently have 30 rounds on hand with 178 ELD-M and Varget which was made a year ago. Speed last recorded at 2730 fps / 43.7 gr. Varget which is decent. I have a new box of 165 Accubonds and 4 boxes of the 180...

Yup, H110 is the best and the only powder I ever used in the .41 Magnum.

Not too sure on this, but just a thought. If using very fine 1000 / 3000 sandpaper wrapped on an undersized bronze brush and wet hone it with a drill with even strokes,,,,🤔

Are those casings getting a little sticky in the cylinders? I recall pushing loads with the .41 Magnum until it was a bit sticky using maximum loads which was on the hot side, and backed off a tad and was back to normal extraction. I would use a round bronze brush with Kroil from time to time...

Send 2 lbs of Blue Dot my way, hard to find those powders I used for my .38 Super years ago. :D Currently replaced Blue Dot with Power Pistol as an alternative and boy its a screamer. Never used Red Dot, but have used Blue Dot mostly for the Super when I used to be in those weekly local pistol...
