The 22 creedmoor thread

A new barrel is a lot easier than continually messing with one that is picky.

Agreed.

I'll shoot the rest of my 88s plinking and then stick to 77s for the rest of the ride on the PVA.

These barrels age like a dog.

Here's 12 77 TMK for the first time in the same gun that shot the 88s yesterday.

The 77s have 39.5gr H4350.

The 77s are carelessly (is carefreelessly a word?) seated at the same depth setting as my hand loaded 88s were set at with no regard for jump in my bootleg 6.5 creedmoor brass that was loaded with a powder drop.

The 88s from yesterday were loaded in nearly perfect Petersen brass and probably all trickled at 39.3gr H4350 based on a few I pulled just for curiousity.

It just has me wondering if a priority to neck turn is really "a thing" at least for hunting purposes.

I concur with Form on the underwhelming barrels.

Regarding the neck turning, short of benchrest the only reason I’d consider it is if you have insufficient neck clearance, that can cause issues. I strongly dislike turning, and sold my neck turner planning to never do it again. Then I got a brass-chamber fit that was too tight and had to borrow one.

I spent at least $500-600 trying to get dud to shoot this summer. Lesson (slowly) learned, maybe,

Despite all the hyperbole by a couple of high volume posters here, seating depth plays a huge part in how well bullets shoot.
The 88s generally shoot well either with a slight jamb ( and no, they don’t get stuck) or a big jump, like .050
I have never had a problem getting them to shoot in multiple guns

I've been playing the middle of your parameters based on crap I read on the internet. I loaded to 2.680 with lands touching at 2.700.

I've been dubious about seating depth for the last year or so...just logically...it has to matter somewhat at the extreme ends of the range, but all the factory ammo is pumped out with no regard for all the variable reamers (and variable reaming) and I bet reloading is performed by a niche of shooters within a niche.

I should have asked you what you consider jammed before I did this but here's 2 groups:

PVA barrel, 1:7 twist, long chamber...lands measured at 2.700 with 88 ELD

I pulled 10 of my 2.680 loads and reseated them 2.705". I pushed on 10 of my 2.680 loads to put them at 2.650".



I thought y'all would appreciate this:

The amazon guy came while I was inside multitasking while the barrel cooled.

Looks like it liked the bigger jump?

10 shot data set...says yeah.
