Not much data out there yet except for Hornady and a blurb from GAP.

So........ I started low, shooting 1 shot each in 1 grain increments for a base line, then went to 3 shot groups, ending at 3199 fps with the 140 VLD's and 3128 fps with the 147 ELD's, all with H-1000.

The print Hornady submitted to JGS had a .188" freebore. Since I was building on a long action, I didn't care about OAL, so I specified a .200" for a little more room for the 147's in case I settled on shooting them. Thought about going even more for the new Berger and JLK's coming, but chickened out.

I'm .020" in the lands for starters, so 140 Bergers are 2.995" and the Hornadys are 3.010"

I'd of never guessed L/A on a S/A chambering,thus the impetus to lose freebore,so as to connect dots on S/A binderless DBM Smooches. I'll ALWAYS happily trade .075" of freebore,so as to set a L/A aside and rock a S/A.

.125" freebore would do it all. Kreedmire SALAMI .200" freebore is too much too,though easily nipped tidily,with binderless DBM's.

I shoot 147's in more than a few chamberings and cain't forget about that Alpha brass and it's splendor in Kreedmire,if only because ES/SD simply don't exist. Have a Fake MacAmillion Grayboe Terrain enroute,if only to see WTF and laugh a little...and it'll likely be another Kreedmire or BR. I'm more than wayyyyyy happy with a Kreedmire,well beyond it's transonic slip and have seen me do so daily.

Less is sooooooo very often more,especially with 30+ Mils remaining on an erector.

I sorta/kinda get where you were coming from,but I personally gotta have more than a few GOOD reasons to go L/A and Hornady brass,which'll easily be replicated in a S/A...ain't ANY of 'em.(grin)

Now as feed/function goes,I've long rated it purty high,mainly because I shoot a smidge. If it weren't a fret,I'd prolly nab a solid bottom S/A 700,go receiver diameter "contour",neutral FL bed the works,scallop a Weatherby-esque ejection port cut out and run it as a Play Toy. Too easy to connect all dots in a S/A,pay heed to things that matter(twist,COAL,throating) and ring the bell. Hell...I've seen me do it! OFTEN.

If'n a transonic slip were a focus,I'd simply grab one of my (3) Montucky 7 Whizzum's and bask in the sanctity of a 200yd zero'd 2950fps 180ELD staying super' to the 2050+ yard line,in even my atmosphere. No thang there and 22.3 Mils of erector travel,is barely 50% of a Fixed Fhuqker's erector travel,then there's 10 more Mils laying in wait on the windshield. Hint. 2050yd full value 10mph wind is a "whopping" 3.4 Mils. Ain't even "fair".(grin)

My "trouble" is,I've seen brass,twist,throat and COAL matter more than a smidge. It goes without saying,that once the novelty wears off,you'll come full circle back to the .123" throated S/A '47 and a OEM 'box Smooch,as a stalwart mainstay...if only because it'll reliably out Agg' same. The PRC's bane,is it SALAMI throating geometry and the great void in platforms that'll accomodate same,even without binders. While I certainly LOVE Hornady boolits,their brass is right at the bottom of the fhuqking heap and that don't sweeten an already heavily compromised deal. Spill your guts on how the new ride treats you.

As an aside,ain't it a hoot,that it's a not so curious constant,that plagiarism is as close as some folks can get?!?

Bless their hearts.

This platform was barrel-less, so OAL length was a non-issue. Again, I only added .012" to the factory freebore dimension, which can be the difference in lot numbers. Doesn't matter if it feeds, as it's just a LR plinker. Regardless, the Crapmore can't hang with the PRC.

I've got 83 MOA remaining, zeroed at 200, and still stay super to over a mile......

My 47 reamer has .123" freebore, and stays under 2.750" hard in the lands, and latest rendition runs 130 VLD's at 3010 in John Holmes guise.

Next up, I concentrated in the middle of the spectrum, starting at 3025 and ending at 3144 with the Bergers, and beginning at 2945 and ending at 3063 with the Hornadys.

It was only around 30*, but I kept the ammo in the truck to keep it around 65* during testing. Due to the nasty little quartering tail wind making it a challenging day, I broke tradition and tested at 100 rather than the normal 200.

After multiple rounds of testing, I found decent loads with the 140 VLD's at 3125, and 147 ELD's at just under 3000, both off the lands for best accuracy.

However, I still wasn't satisfied, so I ordered up a big box of Sierra's new 150 grain Matchkings to test.

I like that rifle and it would be about perfect for my long range steel and deer needs.

I was actively on the search for an action to build a PRC when I came across a very well built 6.5 WSM. Gap tempest, 27” 1:8 benchmark, McMillan HTG with adjustable cheek, Seekins metal with binderless Accurate Mags. I’m getting 3300 out of the 140 vld and 143 eld-x, 3250 with the 147’s and groups have been into the .2-.3 on work up.

Simple pass of 270 WSM brass through the Dies and away it goes.

Will still probably build a PRC for fun but it will be much harder now.

I'd say you did alright.

This action started life as a 25-06, turned first into my 7x300WM, and now the PRC, so anything fatter in diameter was off the table, as I didn't want to open up the feed rails as would be needed with SAUM/WSM hulls.
