Sorry, I got a feeling it turned from “which mould” to “how much is necessary to kill a deer”. We have 1000J at 100m requirement for roe deer here and I know that you have to follow your regulations. Will repost two photos back.Quote:

1000 Joules is about 740ft-lbs. To retain that at 100m, I'd say a .222 would be about the minimum. .223 would do it easily. On the other hand bigger pistol rounds like the .44 magnum, although starting out with the same energy at the muzzle, would fall short at 100m because of the poor efficiency of the bullet in flight.
I don’t want to hijack the topic but since we are talking about Joules and roe deer, yes it’s https://uploads.tapatalk-cdn.com/202...be219b5b1b.jpgQuote:

My last roe buck hit with 130grs MP 311410 HP GC, 300 BLK.
I might just take you up on that someday. Now that we have two brand new grand-nephews in the London area (Beckinham) my better half is starting to hint to me about a visit.Quote:

About energy requirements... Our energy is also measured at 100 meters. Almost any factory 308 Win soft point hunting ammo is moose legal ,at the same time almost all 45-70 factory ammo is underpowered and not moose legal.
Does that make a 308 better big game caliber than 45-70?
Nope. There's very few things walking that a 45/70 cannot take at 100 yards. The 308 is a fine cartridge, but there's something about the ole 45/70 that made it a long range buffalo gun that has stood the test of time. Millions of dead buffalo can confirm that!
Some states here in the US have wonky requirements for legal hunting cartridges also. IMO it mostly boils down to the people making the rules are just ignorant, they don't know enough about what they are trying to rule.
Accurate has quite a few bullet designs with a good sized metplat that will work in the 30-06. I'd lean towards a GC bullet because well having a GC really does not hurt.
Wow! Those regs would be a challenge here. In Michigan we can hunt whitetail deer with anything except rimfire or muzzleloaders smaller than .44". The exception is the south half of the Lower Peninsula where most centerfire rifles are banned (for deer hunting only) to reduce the range because of the population density.
Back on topic- I'm getting 2080fps with the Lee 170FN (182gr as loaded for me) in a .30-30. I powder coat them and am getting no leading. 2 1/2 moa at 100 yards. That's close to what you need. .30-06 should be able to get you there.
My suggestion would be try your Lee 170FN. Worst case- it doesn't work and you need to order a heavier mold. Best case- you get the velocity you need and it's time to go hunting!
Good luck!

I don't know if already mentioned but I powder coat my cast boolits. I have found that with PC I can use a softer alloy. I still use the gas check as well. Judging from my experience I'd say you could get what you need with powder coated boolits that are only mid teens in Bhn hardness.
I'm shooting a 500 S&W @ 32K psi with boolits that are less than 15bhn using non-gas checked powder coated boolits.

There is to much over thinking on cartridges and bullets for deer. A 30/06 is plenty of gun for deer and the best bullet is the one your rifle shoots best. All the Hunter has to do is make a decent shot. Gimmick bullets don't make up for poor shots.
I think you may have missed the OP's needs- he's legally required to get 1700 ft. lbs. at muzzle. To do that he needs to get the Lee 170FN to 2150fps or go with a heavier boolit to reach the required energy levels at lower velocity. My .30-30 load of choice with the Lee 170FN is 27.0 grains of IMR3031 at 1950fps. It's the most accurate I've found. Sufficient for Michigan Whitetails? Yes. Legal for 60lb. Roe Deer in the UK? No.Quote:

Have a great day!

I'll throw out there again I think paper patching to be a good potential option for the OP.
Easily gets him into the velocity range he needs and is easier than you'd expect. On the plus you get the pride of a niche hobby within a niche hobby.
