The first digit?.😂🙄

 

All joking aside i would say very little. Other than aesthetics and some manufacturing processes I believe the barrels have the same bore diameter and use the same family of chokes(625?) Im sure more knowledgeable people will chime in and ill add my experience is really only with 325s.

 

Each one was 100x better than the last one but only according to Browning.

 

The side profile of the stock to receiver is different than a regular Citori on the 525 and 625. The 325 was introduced in 1993, 425 in 1995, 525 in 2002, and 625 in 2008. Internals most likely the same. Externally, embellished with various styles of stock checkering and receiver pseudo engraving. Possibly some changes in stock dimensions, barrel length, and choke systems. My guess, as I haven't researched it very deeply.

 

The 425 uses Invector Chokes, 525 uses Invector + I believe the 626 uses Invector + as well. Wood layout is a little different, internal parts are interchangeable for the most part.

 

Nope. All three use Invector Plus chokes. There are also differences in the stock configuration on all three.

The checkering pattern on the625 was horrid.

 

I disagree my 625 grade 3 20ga has very nice checkering as does m 525 grade 3 12 ga and my ultra XS 28 ga is good also for its age

 

Far better-quality control on the B-325 and B-425 in the earlier days.
I personally would not buy a 625 or 725, I've seen and heard too much.

That's my story and I'm sticken to it.

 

I have a 625 that I’ve been using for several years and have had no problems other than the lower firing pin needing to be replaced about every 15-18000 rounds. It’s built like a tank , heavy enough to absorb recoil , and swings nicely for me. But that’s just me. I did switch over to a Model 32 Krieghoff that I’ve been shooting for about a year It had nothing to do with the 625 not performing.

 

The 525 had that weird slant on the receiver to butt stock fit.
The current CXS is just an updated 425.

 

325s had both chokes and were chopper lump barrels.
The backbored barrels are invector plus in all models
425 and forward were monoblock.
525 upgrades were supposed to be lighter barrels and improved trigger.
525 and 625 had straighter grips with bigger palm swells.
525 and 625 both had the angle on the reciever.
I don't know any differences between the 525 and 625 other than cosmetic.

 

The 525 and the 625 both have the forcing cones opened up in the 12 ga. guns from the factory. I am not sure if the 725s or 825s have the forcing cones opened up or not.

 

I just purchased a 325 12 gauge with 30 inch barrels, ported with invector plus chokes it is working out quite well for me.

 

Can you post a pic?

 

could you message me on here with your text number email and I will get a couple to you the 325 I picked up had very few shells shot thru it and has original box manual hang tag etc. Shot it today for 2nd time and I do not mine now the price I paid for it.The gun seems to fit me well.

 

The 525 and the 625 have their own stocks. 325-425 and the CXs etc have their own stocks and the 725 has yet its own stock. I do not know if the 725 and the 825 have the same stocks or not.

 

BROWNING has something for everyone now, Wow that new 825 in the pro sport is sure pricey! Really like the engraving on the receiver. Looks like it has everything a shooter needs but at 4k it should.

 

Have 3 Brownings, a 525 in 20 ga. And two 28 ga. A Cynergy and a 725. My favorite is the 525.

 

my 425 in 20 gauge is still my favorite with 30 inch barrels would like to get a 525 in a competition grade sure would like to shoot one first tho lot of money to throw out there without knowing if it is best for me.
