I've got some Hornady brass on a test in 30-06 and 300 WBY. 30-06 is factory loaded ammo. 300 Wby was new old manufacture brass I picked up.Six firings on the 06 brass, neck sized only. Going to do a FL sizing this round and bump shoulder .001. Case web measured at the extractor groove has...

Sounds like the OP has trouble shot a few things on the rifle. One thing to try is to torque down the front gaurd screw tighter and see if it changes POI. This can be an indicator that there is bedding issue if you see a POI shift.

FL die to chamber compatability in factory chambered rifles is all over the board as we all know. It is rare for me to over cam when sizing my current rifles brass, but I have a couple that need it. I agree the OP"s brass is out of spec/bad, .006 variance on the shoulder is a lot.

How much shoulder bump are you seeing FL sizing new brass? I generally lower the expander ball on FL dies and just make sure the necks are where I'm going to be loading them. Saves having to lube and then clean them, normally there is little to no resistance sizing new cases

Have you measured any fired cases out of the rifle? If not I would load and fire the cases that will chamber to get some measurements of the chamber. Think I would have your gunsmith have a look at it before you bump the shoulders back on the brass.

Give the modified case mouth a little inside neck chamfer and see if that helps. Also you could load up a dummy round to Sierra's OACL and try it in the gun.

I shot factory loaded 30-06 with the 175 TA. In my rifle they are .0870 off the lands. In three different outings they shot 3/4" or a little better. MV was 2740, finding this bullet has been impossible. Will be interesting to see how they perform when pushed harder.

Totally agree with you that there is a point the barrel needs to go. I also read that Tubbs said to use caution with FF more aggressive grit bullets on higher end lapped barrels. I've got a Montana Rifle Company barrel in 300 WSM I'm using the finer grit bullets on . Barrel looks great but has...

Final Finish pack , think the TMS is throat maintenance system.

If your up for an experiment you could fire a 50 round pack of Tubbs lapping bullets thru the barrel. Picked up a 25-06 with a custom barrel on it. The barrel didn't look to bad, had quite a bit of boring marks but lands looked good. Barrel pressured up well below max book loads and copper was...

20 to 25 passes usually does the trick with Iosso or JB.

This has been my norm for using magnum primers as well. I have been trying Mag primers in some lighter loads for a while, I tried Remington 9 1/2 M's in a 6 CM load of 42 grains of 6.5 StaBall. Had an SD drop from mid teen's to mid single digits, picked up a little velocity but nothing not much...

I've tried StaBall 6.5 powder in a few different cartridges. In all cases it has had higher velocity before pressure signs than H4350. SD's weren't as good in some of the cartridges as H4350, and the best results with StaBall were using hotter primers. Temp stability seems to be better than any...

Don't know about the TMK but The ELDM bullets showing a solid ring on the bullet is normal. With bullet having a secant ogive the bullet usually stop at the end of the throat, rather than contacting the rifling. Bearing surface of the bullet should be close to were your reamer print shows the...
