Fully agree with you there!
And sure here goes:
I've used Barnes bullets on game in the following calibres, models and weights:
.264 - 100 Grain TTSX
.284 - 120 Grain TTSX
.308 - 130 Grain TTSX, 150 Grain TTSX, 150 Grain TSX, 175 Grain LRX
.375 - 300 Grain TSX
.458 - 450 Grain TSX
Head/Neck shots:
Barnes will function like any other bullet in my experience for Head/Neck shooting, you need to cause catastrophic damage to the brain/spinal cord in order to kill.
With the Barnes this means your POA needs to be of a path that leads through either the brain cavity or the Spine as the wound channel is 1.5-2" around the path of the bullet depending on calibre.
I have always found regardless of entrance angle they have tracked very straight and penetrated well through the spine/skull. This gives me confidence when taking front-on headshots to go through the bridge of the nose if necessary, knowing I will not suffer a surface blow up like I may have done if I was using a V-Max or similar highly frangible lead option.
With side-on headshots I just aim to place the shot through the brain cavity typically aiming just in front of the base of the ear (alter for angle to place shot centrally within the brain as appropriate).
My experience of headshooting with the Barnes has always been they've dropped on the spot very dead - I certainly haven't found they pencil when directed through the brain cavity or spine. To be honest the result is generally very graphic and I typically have two flaps of skin with the ears on and nothing in between. I won't post pictures for obvious reasons.
Chest Shots:
Barnes are a high weight retention bullet and as such in my experience you have fantastic penetration and very straight tracking through the thoracic cavity - this means if it is in the line of (or 1.5-2" around) your POI you can consider it shredded.
One key advantage of the straight tracking and high penetration I have found is the ability to make heavily quartering to/away shots and being able to predict very reliably where it will exit, rather than worrying if it will make it to the vital organs with the longer route or being concerned it may curve or deviate as it expands.
I have found they work very well when combined with the following shot placement, with bang flops being the standard response I see (to the point where it does concern me when they run).
The damage done is generally very localised to the shot area, typically not seeing massive bruising/excessive hematoma, again the non-lead benefit of eating right up to the shot site applies, which makes for generally very tidy carcasses.
Bullet limitations:
These bullets are optimal inside a terminal velocity of 2200-3300FPS in my experience, at higher velocities you tend to start seeing the odd petal shear off and the damage increases seemingly exponentially with the impact velocity after the upper limit (3650FPS was a little much...). On the lower end, beneath 2200 FPS the wound channel is narrowing and expansion is becoming marginal, I would not try to operate the bullets below this even though they will likely kill eventually as you will likely start to see prolonged runs.
(the velocity range will vary somewhat by which model of bullet, calibre and weight you choose, however that range seems to be applicable to all I've tried, with some bullets withstanding higher/lower Terminal velocities better)
Accuracy
Overall for myself, the Barnes have proved to be an accurate bullet, with most loads producing sub 0.5 MOA groups every time (in my rifles, handloading the bullets). Like any bullet there will be the odd rifle that may not like a specific bullet, however I haven't found these to be difficult to work loads up for generally. There is variation between batches as found with most mass-produced bullets, however within the batches I have found them to be very consistent.
Overview
In my opinion, for the majority of stalkers in the UK these bullets will perform well, providing a good all round performance within typical stalking ranges. Providing you keep the Terminal velocity within the range mentioned above you should avoid dramas with reliable and consistent expansion and penetration.
The scenarios I would see these bullets being less ideal is Extended range shooting (pushing below the 2200 FPS limit), only head/neck shooting (there may be less margin for error compared to a fragmenting design, however I haven't found this an issue at all personally) or for use in a very small cased round where Muzzle velocities are on the lower end.
