Has anybody tried something close to this? I know everybody wants to run the heavier bullets but I'm just curious. A 140 Berger or 140/143 Hammer at around 3400fps?
7 PRC & 140 GR bullets?

I say go for it. I like light for cartridge loadings with monos.
I shot 140's in my 7STW and loved them. Lazerbeam trajectory and hit like Thor's hammer.
Did it for 25yrs with a 7RM. Accubonds also, they seem to do better the faster they go.
147 Apex Afterburners topped out right at 3200 in my PRC with n560.
Going to play with them more soon. 26” barrel.
They weren’t fussy it didn’t appear, from what I saw.
140g Bergers vld hunting bullets are better suited for a 7/08. The 140g Nosler Combined technology bullets never detonated on the surface, and we never killed deer under 75 yards with them, from 7 Mag at 3250 to 7 STW at 3650. Having said that, the Nosler 150g Ballistic tips are a very different animal vs the 140g, they seem to be much tougher or penetrate better on quartering shots. 120g and 140s is what we shot in our 7 STW's.
So, the 7 PRC has almost identical case capacity of the 7 Rem mag. If you had a reamer set up to shoot 120-140g bullets(standard Rem 7 Mag SAAMI .110 freebore works just fine), you should expect exceptional accuracy, just like the 7 Rem Mag achieves. However, we found in all of our 7mm that the 120 and 140g Noslers shot very, very tiny bug holes when they were seated to just barely touch the lands or .003 off the lands. So, jumping the noslers, is NOT part of our family's way of doing things. We get 2.5-3.5" groups at 600 yards with the Rem 7 mags that have been bedded, freefloated, with muzzle break, 6-24 scopes, we have our own 700 yard rifle range.

In the 7 Rem mag, we shoot a load of R# 25, Winchester Mag primer, 150g Nosler ballistic tip at 3250 fps, SD is 9 fps. The Winchester Mag primer is the key to this low SD, and the groups are sub 1/3" with the bullets kissing the lands. I would expect no less from a 7 PRC, but Fed 215s shot 5/8-3/4" groups vs sub 1/3" of the Win Mag primers. The powder charge would be max found in Alliant manuals about 10 years ago. Soft rem brass lasts three firings due to primer pockets, I have plenty, so I don't care. These are hunting rifles, not target rifles. New brass shot just as well as fire-formed brass, and we full-length size on every firing.
ON hogs, we use the 154g Hornady Sp, which will shoot a hole through both shoulders of a 350 lb hog. The family has killed 7 bulls with the 154g Hornady before the invention of the HIGH bc bullets, the last bull was at 550 yards.

I played around with 143 HH.
In my 7PRC, but it was back when I only had Hornady brass.
N-560 will get you the velocity your looking for, just don't use Hornady brass.

I loaded the 145gr Hammer HHT in mine last year at 3400 fps using rl26. I ran the 170 HHT just to show that you don't have to run Hammers fast for good performance. Frankly the 145gr HHT will out run the 170 gr to 700 yards or so. My personal preference would be the 145gr HHT.

I wholeheartedly agree with this. My ex-wife and I used these out of either the 7-08 or 7STW and no animal stayed standing very long, most were on the ground within 20. Any angle and they reached the vitals.
We never recovered many fragments, but core and jacket were separated if used within 100.
I’ve never used a 140, the ex was using 120g quite a bit and they are tough too.
Cheers.
Isn't the 7prc 3-4 grains less capacity than the 7rm?
ADG numbers say 1.9grs
Gotcha.
