I have a 7 twist Savage LRPV that I shoot both the Berger 80 VLD and the 85.5 Hybrid bullets . So far , I've been using Varget with outstanding results . Just curious if anyone has had success with V540 powder as it's actually more available then Varget these days .
 
I’ve heard it’s not as dense as Varget, Therefore not allowing enough powder into a .223 case. I’ve been using reloader 15 with ok results, but I’ve run out of room in the case as well. I can hit 3000fps with 80gr bullets, but am down around 2900 with 88-90gr. 1-7” twist, no pressure signs.
It becomes a pain to maintain consistent seating depth when the load is too compressed.
 
I am getting 3000fps with the Berger 80 VLD and 2950fps with the 85.5's with Varget in Starline and Lapua brass with no pressure issues at all . I can push it faster but don't really see the need too . It's not super compressed so bullet seating is consistent . Varget is pretty scarce these day so looking for an alternative . Rifle is shooting sub 1/2 MOA at distance and I really don't want to give that up .
 
When doing load development to go to the 2013 World F-class shoot Varget all but dried up. Worked up two new loads to the same velocity with N140 and N150 (Shooting 155 Lapua Scenars. Never went back to Varget
Next was the 90g Bergers in .223 (first generation) with a 31 inch 7 twist tube. Was trying N550 first, but had much better results with N140.(super accurate at 300m and 500m, couldn't keep them on the target at 800m)(too slow) I have tried N540 but eventually lost interest. Those early 90g Bergers were a ##### to tune.
N540 worked particularly well with the Lapua 77s
Hope this helps
 
Here's a chart for fastest to slowest, within SAAMI max pressure of 55,000psi

Code:
Cartridge          : .223 Rem
Bullet             : .224, 85.5, Berger LR Hybrid
Useable Case Capaci: 26.583 grain H2O = 1.726 cm³
Cartridge O.A.L. L6: 2.450 inch = 62.23 mm
Barrel Length      : 24.0 inch = 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 55000 psi, or 379 MPa
or a maximum loading ratio or filling of 104 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !

8 loads produced a Loading Ratio below user-defined minimum of 80%. These powders have been skipped.

I’ve replaced any loads I had that used Varget with N140 in several different cartridges. Work up to the same velocity and accuracy usually follows. Find it cleaner burning as well.
 
I've been told by someone that tried the 500- series VV powders that they're more sensitive to temperature variation than the 100- series.
Whether that's true or not, I have no personal experience.
