Group B inspires me! That's exactly the sort of group I was hoping to see!Yew tree bullets are excellent
Shot a single sighted at 310yds the other day, when there was next to no wind, went within 1/4” of expected impact point
I may have to give these Yew Tree bullets a wee try!
Mine do that out of a factory barrel,plenty speed and plenty jump
Barnes, Fox, Virtus groups as good as lead if I do my part 1" or less for 3 shots.
Why on earth do you need a deer bullet to do that!
Try yew tree, they did similar to yours at 100 in 6.5x55…
You are either joking or you have a decimal point in the wrong place(s) or you are destined for eternal disappointment even with conventional lead cored bullets.
To put your expectations into perspective:
In 100 yard or metre benchrest rifle (BR) competition a competition consists of shooting five - 5 shot groups (plus a discounted warm up group). In these competitions a group less than 0.010” (CTC) is called a ‘screamer’ & often you get a little badge for achieving it because even at top flight BR level it’s not that common.
Below are the results of the top 10 in the 2023 Benchrest World Championship 100m event. Shot off concrete benches with the most stable rests available using some of the most accurate/precise rifles made. Ditto the bullets (jacketed lead cored). Each measurement (A, B etc) is for 5 shot group (recorded as a centre to centre measurement). The ‘Agg’ is the average of the five matches (A to E).

There are two schools of thought about monolithic bullets.
1) the naysayers who believe their 2nd amendment rights are completely violated because someone has suggested that they move away from lead bullets. They are stuck in the belief that lead is a perfectly safe material have chewed the lead paint of their childhood cot and toys. They never want to use non lead and at the same time pour scorn on everyone else.
They will seen have groups being posted on the accuracy of monolithics. These of course are created by AI, not statistically significant and that BCs of monolithics would never allow such performance.
They also believe that they are totally capable of shooting sub MoA groups with any bullet or brand of ammo in their rifles, and that of course you need sub 1/2 MoA accuracy to be able to shoot any deer, especially if shooting them at short distances of 500m, which of course they do all the time.
2) those who actually use monolithic bullets and find that they shoot and kill well and will continue to use them.

Not sure who you've been speaking to as I know plenty that are using Cu with success.
Personally I've tried factory Fox Cu in .222, .243 and 7x57 from @Edinburgh Rifles and all produce sub MoA groups to the same level of precision as Pb.
As for demanding such high levels of precision, the clue is in the name - 'stalking'. It's not sniping or bench rest shooting. Within sensible distances ~1 MoA is adequate.

Just back from Mull. 3 hinds. 1 at 180. Hind and calf at 220. Barnes 130 grain ttsx homeloads in my 30.06 and all dropped on the spot. The accuracy as good as lead.

Peregrine VLR4 150gr in my 30-06 give 0.5 MOA accuracy and kill with authority out to 350m. All the Peregrines I’ve tried are very, very accurate.

As above- provided you drop the bullet weight down- they are just as accurate IME.
I personally find that they don't drop deer quite as well at extended ranges- the material just doesn't expand as well. Their speed envelope within which they expand is narrower than lead. The more fragmenting bullets like Yew Tree have avoided this to a certain extent- and shots inside 200-250 yards are normally ok provided the bullet is going fast enough.
I can't see them performing as well at long distance target ranges- that must be where the limits of the physics comes in ?

What people are missing out on completely is that there are two kinds of copper bullets. Those that are pressed and those that are milled. The former may show some some unexpected behaviour (flyers) while the latter are capable of producing accuracy which is superior to conventional cup'n'core bullets due to their absolute uniformity.
Very nice, don’t you just love it when the accuracy node is at the highest charge weight
Cannot agree with the OP - Sako Powerhead Blade 308W factory ammo with 162gn bullet shot closer to half moa than moa in my standard Tikka M595 so grouping excellent as far as expectations from factory ammo go. Accuracy is down to the shooter! As far as performance goes, no issues there at all even at 300 yards on fallow.
