Vertical Where to start?

What kind of fill should we use in front and rear bags?

Only speaking for myself you understand. I use fine paver sand in my front, filled 95% ish
My current recipe for the rear is chromite ( heavy sand) at 95 %
fine paver sand in the ears, however I’m fixin to spearmint a bit wit da rear.

I hate vertical .....

Really???

I've never heard of this? What could possibly be the reason?

Bouncing on the hardness

Is fine paver sand what you find at the hardware store?

Its for brick sidewalks. Most places carry play sand at a minimum and it works well

Have you checked the bedding? -Al

Here’s what I know.
There are a few specialty stores were you can find extra fine paver sand, I use Valley supply ( Const supplies) it very light in color and texture almost like salt it doesn’t really compact or get overly hard in the bag. The sand that came in my Protector bag is tan with slightly larger granularity and not as concentric but tends to hold its shape a little better under heavy use.
Chromite is purchased as heavy sand; mine came from Protector, now this product is very dirty and very fine with a tendency to pack not only into a brick in the bag but I suspect an MSDS report might be in order for people with sensitive breathing conditions. Emphysema, COPD , etc.
I’ve also used Black Diamond media blast purchased from tractor supply that isn’t quite as heavy, much sharper granulated that I felt packed quite tightly as well. Read the MSDS on that product as well.
Lowe’s and Home Depot sell traditional playground sand as well as paver sand in approx 40 lb bags for a decent price however I haven’t sampled them for weight or granularity therefore any comment would be conjecture.

There ya go fellas

Yes,
The rifle has been shooting small, something changed. Saturday shooting good, Tuesday, not so much. Temperature Saturday was 42*F, Tuesday it was 38*F.

When you change bolts, are the different bolts complete or do you swap the firing pin assy from bolt to bolt? -Al

Both bolts are complete

Have you sorted you bullets by overall length? If not, give that a try, keeping them batched into .002"-.003" lots.

I got bit earlier this year assuming my custom bullets were good to go on their OAL. They weren't Thanks @Torge for catching this for me.

Good shooting.

Decock the bolts and measure the firing pin protrusion on each. Then, repeat the process with the bolt(s) in the action, pull the trigger and compare to your previous measurements. -Al

Mag bolt in the rifle, firing pin falls .235”, out of the rifle .257”. firing pin protrusion out of the rifle is .058”.

Standard bolt firing pin falls, in the rifle .256”, out of the rifle .282. Firing pin protrusion out of the rifle is .058”.

Can you check the pin protrusion with the bolt(s) in the action? You can use a metal straight edge across the action face for the dial caliper to rest on. -Al

Just did that,
Mag measured .061”
STD measured .055”

attached is a video of what I believe is the answer to the vertical stringing.

Watch the lag time between pulling the trigger and actual firing pin fall.

Maybe I am wrong. I will test with a different trigger in the next day or two and post those results.

The trigger was "hanging up" a bit the day I had the vertical stringing issue, I believe this is temperature related.
Yesterday evening, I pulled the trigger out and installed it in my PPC. It functioned well, so I locked it in one of my vehicles for a few hours in an unheated area. This morning, the trigger was "hanging up" again.
I will clean the trigger today.... maybe this is the problem?

this video was taken about 10-12 minutes after bringing the rifle into the warmth of the house. I keep my trigger pulling hand on the opposite side of the rifle so firing pin operation in more visible.
Pay particular attention to the last trigger pull, the delay is super obvious (after trigger pull watch for firing pin fall).

It does seem slow, fwiw. It's winter time and cold weather will gel old lubes etc and slow the trigger and firing pin down..sometimes much worse than yours.
IMO, it's certainly worth cleaning, thoroughly, both the trigger and inside of the bolt. I'd soak in acetone, spray out with brake cleaner, blow dry, repeat, then douse in lighter fluid. Even better, disassemble the trigger and do same. When was the fp spring changed last? I change mine at minimum, every two years.

Just finished taking the trigger apart, it was quite clean.
No grease or liq oil on firing pin.

Edit,
I replace firing pin springs each year

It appears to be slow for some other reason, then. Maybe it's just the way my feeble mind sees the video...Entirely possible.

Any evidence of the cocking piece dragging on the trigger connector? Some black Magic Marker on the trigger connector can show this. -Al
