I’ll take the 30mm

Any scratches?

Who is making chassis and stocks for this medium inlet size? I can’t find anything.

What barrel brand?

I agree with Adam’s assessment. Most of the fine ball powders and small stick flow great. The larger stick powders become very sensitive to the tube speed. Likely why so many people have better success running the small tube fast. The trickle rate becomes more predictable/uniform. Excited...

I’m still in the unsure camp on the tip. It does appear to reduce the flow down by .04gr a second. Maybe this allows a higher small tube speed which it almost appears the powder is better behaved. I do see the kernels approach the end in a more organized manner. I did notice that if you just...

I made something similar from a mechanical pencil eraser cap. Didn’t really do anything. Must be missing something?

Is this a fluke? I can’t follow how this even gets you to a perfect single file line of kernels.

I've been using it. Do you let your press cam over when using it? I've had problems, but they might be my fault. I had better results tonight by setting the die up to not let the press cam over and only apply ~25lbs to the handle.

If you seat to 2.800" COAL in lapua brass, you will begin to run into compressed loads above about ~43g. I've seen people say 42.6 to 43.8g of varget for the 178gr in lapua brass. I'm in the process of working up a 178gr load for an 18" barrel gun. 43g chronos about the same as 175gr Federal...

Ok, so I got frustrated tonight and started over from scratch. I reset my Lee Collet die and decide to not let the press cam over anymore. The two turns past when the shell holder makes contact instructions did not work and caused the die to do nothing. I then started over and just started...

Yep it is really that far down the nose. Stem is definitely deep enough for the long bullets. My brass neck OD before seating the bullet is .334"-.3345". After is is .337". I did have a few that were .3375" and one .338". I noted which ones seated easy and they don't really measure any...

Brass is new lapua brass. I ran a Lee Collet die with a .001" undersize mandrel to make sure the necks were round. Trimmed all to 2.005" and then ran them through the RCBS case prep center. The seater stem contacts the bullet where the bullet diameter is .285", this appears to be normal since...

Ok, so a quick update... I ordered a custom seating stem from Forster. Appears to make better contact with the bullet, still varying base to ogive measurements after seating. Still makes a mark on the bullet, but at least the mark is large and much more consistent so it is likely the stem is...

What primer and barrel length?

I've been playing around with quickload with the same components. Given your barrel length and seating depth, you should be on an optimal barrel time node at ~42.6g. Does it chrono at ~2475fps? Mostly trying to figure out of this darn program works.

I agree hopefully I can stop sorting after I get done with OCW

I think I will try around 43g again. I did weigh my brass after prep and used brass that was within +/- 0.1g of each other.

Well I just worked through all the stuff in quickload and have measured velocities and charge weights matching. An 18" barrel has a usable optimum barrel time of .989ms. Quickload suggests a 43g charge. A 43g charge was giving me a MV of about 2475fps and a 43.8g charge was giving me about...
