Scotland Lead Free Roe Load for .222/.223 Remington

My 1985 BSA 22-250 shoots Hornady 50grn solids perfectly to the same point of aim as Nosler 55grn lead.
The Hornady could be 55grn I would have to check
The Hornady could be 55grn I would have to check
Because a 50gr with a tip is too long for a 1:14” twist
Without a tip it isn’t
It’s why there are no other factory loads that are deer legal in non lead for .222 and .22-250
The vast majority of 22-250 rifles have a very slow twist 1-14. That is changing for the 22-250, I am not aware of 222 rifles being produced with a faster twist. Isn't projectile bearing surface length the factor in stability? As always custom barrels can have any twist rate desired. I may have to experiment in my slow twist CZ550 with the TTSX just to see what happens tip on and off.
Faster twist rates in .222/.22-250 are not available as factory options as far as I am aware
The cartridge is designed to run light 50 and 55gr bullet at higher velocities
The stability issue only comes about when using less dense materials (copper/brass) or when choosing a gullet design with a very long profile
Bearing surface does have a relevance but only as a function of increased length
You can’t have a long bullet of the same mass without losing some bearing surface
TTSX has a much longer profile than some other bullets so may not work even with the tip pulled
Only your rifle can tell you.

I quite agree sir, I was interested enough to look at on line data and found Barnes at least in 223 recommends 1-8 at 62 grns. That weight is minimum required by law for deer and North American Pronghorn in my state.
I wrote an article in the Gun Trade World magazine a few years ago, on how the fact that there is zero evidence for lead in bullets being an environmental hazard will not stop the gun trade being supportive of the banning of lead in bullets. The posts in this thread have demonstrated the reason why. When the ban on lead in firearms ammunition components comes into force - as indeed it will - all (an awful lot of ) shooters will have to scrap their entirely adequate rifles and buy new to satisfy the new requirement. That will be a big cash bonanza for the gun trade and you will not see anyone in the gun trade opposing that.
The real prize which has the gun trade dribbling in anticipation is the ban on lead in any Olympic shooting sports. Hunting sports will quickly follow. That will force 22LR ammo and rifle makers to start developing lead free ammo and rifles that can shoot it. The market in 22LR is by far the biggest ammo market in the world, with world-wide production running at around 5 billion rounds a year! At that point, everyone with a 22LR rifle will have to scrap it and buy new..... I can hardly wait!

I think S&L have a 1-12" in 222 Rem.
Stability is a function of twist and velocity so what stabilises at 22-250 velocities in a 1:14 may not at 222 velocities
Length is the determining factor
Dear All, I'm using this monolithic HP bullet caliber .224'' in my 222 Remington ( rifle 527 GRS barrel lenght 26'' ). The Vo=1097m/s with 21.9 gr N120 and gives 1/4 to 1/2 MOA at 100 meters.
Gyroscopic stability coefficient 1.57 at 3400fps (lenght of the projectile 14mm exactly)
The bullet is designed, produced and available in France. It has been specifically designed & developped for the barrels in 222 / 223 having a twist rate of 1-14''
For more details dont't hesitate to drop me a message, I'll provide more.
Best regards

The issue is not environmental, it is food standards related.
There are countless sources of evidence identifying the hazards of eating lead.
The attack on the production of food as the primary reason for shooting game is directly linked to the idea that if our "food" is full of lead it can not be commercially viable and therefore the justification for shooting is removed.
This monolithic bullet is mainly used for fox and roe. Occasionnaly for (small) boars up to 40 kg.
The stabilization of a copper bullet weighting 50 grains is ... more than problematic in a barrel 1 - 14''
37,6 grains for 14mm long is what we've obtained - longer bullets are not stabilized.
I undestand that 50 grain bullet is legal for roe in Scotland.
Terminal effect of the 37.6 grain monolithic bullet can (could) de compared to 50 to 55 grain conventional bullets.
Wish you good chance to get what you are looking for

That's absolutely true, we've to face roughly the same situation in France.
That's one of the main reason why we've created a line of monolithic bullets which are not only leadfree but which are clean and certified in terms of selected materials ( type of copper selected and also the tip of the bullet is machined with a material compliant with the F.D.A.)
It's only one feature on the new line.
Phytagorian and decoppering aerofoil are other features allowing improved performances, to give only few examples. Mass is kept after expansion.

A simple picture showing for example a 308 - 130 grains bullet 
Tri zones for the new pythagorian expansion (easily visibles by zooming the image)
CNC machined - tolerance 1 micrometer copper and tip (also machined, NOT injected).

My point was that there is no evidence that using bullets with lead is harmful. It is an assumption that is deemed to be self evident. And the whole theme of "lead in the food chain" is hung on the peg of "damaging the environment", another button to push in opposition to the shooting sports.
My other point, however, is that you will not see any (serious) opposition to this from the gun trade, for the reasons I laid out...
