22-250 load development

The twist in the barrel is less important than the variations in barrel internal sizes.
That is why we start start low and work up. I would go ahead and work your loads up as you would regardless of twist rate. If you have a "tight" barrel then you will reach signs of pressure quicker than if you had a "loose" barrel. Let your gun guide you on load pressures.

I have a very accurate .22-250 load using Sierra 52 gr. HPBT Match bullets (#1410) that is devastating on everything up the size of a coyote.

Fox, crow, muntjac & Chinese water deer.
Can't legally use anything except expanding bullets on live quarry bigger than a rabbit here.

Just interested: what's the definition of "expanding bullets"? Anything except FMJ's? And is there a place for bullets without lead?

Yup. Each load's in at least four stages, with none currently at "book max".
I'll only go up to that if it appears it's warranted - saves pulling down a bunch because of pressure signs.

IIRC it states "designed to expand on impact".

There's quite a few here who use either Barnes or Fox non lead monolithics, though the latter didn't perform particularly well when slimjim tried some I sent him - a fairly narrow velocity range where they performed properly.

Such things always seem funny. A solid to hunt elephants will expand on impact, on an elephant, but not on smaller game nor on a safety vest...
And when you file a flat nose on a FMJ, you're designing it to expand on impact...

Eachtime someone makes some new rulings on firearms there is always room for excape routes Smile

For game hunting they want bullets that kill clean and fast but on the battlefield they want bullets that are not as clean or fast... I don't understand unless they follow the thought that it takes more men out of the fight when you wound a man than if you kill him outright.
It also allows you to target those that come to help the injured. There are reasons that war is hell on both fronts.

That is exactly the thought process behind it Paul.
Kill the bloke you take 1 enemy out of the battle, wound him and it takes 9 or 10 people and a lot of money to retrieve him and treat him.
War is an economic weapon.
All the above doesnt work on certain race colours or a particular religion, better just to kill them out right.
Which is why the US Army is looking at 6.8mm for personal weapons instead of 5.56, and looking at .338 magnum for medium machine gun,.

AMEN Pete. It takes 6 men plus a medic to stretcher a wounded off the battlefield, plus the time to do it safely avoiding more injuries. That is a 60% reduction in the size of an infantry section...even more so if it’s the machine gunner who is the injured patient given the capabilities of his weapon and his experience.

yeah but the whole geneva convention thing has been sidestepped for years and a lot of "foes" dont abide by it anyway....why do you think certain brands of projectile are marketed as OTM open tip match????
AMAX or ELDM are another....allowed to be used as target ammunition,let me tell you the AMAX leaves an old dumdum in its dust.

is there a place for mono projectiles???? YES but ONLY IF you match body weight and resistance EG the 50 grn ttsx Im using in .223 preform awesomely on deer and pigs but would probably be piss poor on wallabies or foxes as they wouldnt meet enough resistance to open up properly.
