.270win and lead free ammunition

Nice bull. Where did the bullet hit?

Lungs. I find that when I shoot critters there they die.

I have never shot an animal with them, but they were not accurate in the rifle that I loaded them.for. It is my feeling that they were created more to satisfy the "Greenies" than to improve the efficiency of a cartridge. Copper is less dense than lead, and harder. It brings it's own issues.

You don’t know what you are missing! They are worth trying. I find that I am more likely to get pass through shots with them and good exit holes. I’ve used barnes for the last 3 safaris and use them in the USA for elk, deer and antelope. I’ve used a variety of other bullets too, but if the rifle likes barnes, i pick them first.

The university of minnesota did a study on led fragmentation in hunted game. It was alarming. I have kids. If I don’t have to take a risk of them (or me) eating lead, that is a big positive.

You have never used the TSX or other copper monolithic bullet on animals, and that qualifies you to claim they are not good hunting bullets? How so?

My advice is that you try them and then build an opinion based on actual experience. You are correct that they were developed and required in some states to satisfy the Greenies misguided environmentalist BS. But, they still work very well if you know how to choose them for a given rifle.

Try them but, first do this... Use a lighter bullet than your usual. If your rifle likes a 150g bullet then use the next size lighter in the Barnes or other monolithic. Why? Because for the same weight bullet the Barnes must be longer and thus harder to stabilize. My 7mm/08 shoots 1/2" groups with a 140g Barnes TTSX and likewise shoots a 150g Swift Scirocco just as well. My 7mm Mag likes a 175g bonded copper/lead bullet but loves the 160g Barnes copper bullet. Also shoots 1/2" at 100y.

I killed a Blue Wildebeest with a 375HH loaded with the TSX 300g bullet and the first shot was fatal a frontal at 180y off sticks and it dropped after a 60y run. We shot it two more times just to shorten the finish but it never regained its feet. Those bullets expanded to 2.0x and 2.2x and penetrated nearly 3 ft of the animal. It was a SCI Gold Medal record (preliminary) and weighed over 600lbs. Weight retention was 100%. I am not a great fan of the monolithics but my experience with them has been great.

I also have many animals killed quite dead with lead based bullets. At which point did mono bullets become more effective than lead based bullets? That was the original question. I stirred up the shit storm by saying that I didn't think an all all copper bullet would make a .270 more capable than it is with quality leaded bullets. I still don't. As an example, I shot a very large waterbuck in the chest from the front. He took about two steps and rolled into th bottom of a dry river bed. He was very dead and did not require any more shots from my .300 WM.

Using Nosler AccuBonds I haven't had to shoot anything more than once except for a bull moose that bailed out at 165 yards. The first shot went through his back leg. I suppose that a Barnes bullet would have killed him with a shot like that? Using the .300, a 7 RM and a 7-08. Many animals have died in Washington, B.C. and Zimbabwe. I see no reason to change to mono bullets.

And yet a study done it n.humans that ate a lot of game shot with lead bullets and bird shot did not show higher concentrations of lead in their blood streams than did those that did not eat game meat. I think of my grandparents that all ate game for their entire lives. They all died as old people. So lead in game meat doesn't concern me.

Good. Now did you recover the bullet? Had it expanded? I have read many accounts of mono bullets failing to expand on long shots.

Not recovered on the elk. Prior year I shot a caribou and a moose in Manitoba with Nosler E-tips in a 300 WM at 350 and 300 yards respectively. Great performance. No issues. Love non-lead bullets

I get your point brother. I think we are mostly of the same mind on this issue. You sound like a very experienced hunter.

I too have killed many critters using a variety of lead core bullets. For many years, my go to was either the 308 or the 270 loaded with Nosler BT's in 165g or 130g respectively. For deer & wild boar over about 35yrs or so, these resulted in 1-shot kills 100% of the time. In Africa, I used an old vintage FN Browning Mauser style rifle in 308 to take everything from little Duiker to a very large Gemsbok all with one shot each with 180g Fed Fusion lead core bonded bullets. I could not have had better results had I struck them with lightning. Stunning performance and none ran more than 60y and most dropped in their tracks. So, I agree with you that lead core bullets get the job done. But, that fact does not make the copper TSX type bullets a bad choice. They are simply different.

Compared to a quality lead core bonded bullet I think the main differences compared to a copper expanding bullet are these:

• Copper expanding bullet will often penetrate deeper.
• Copper will retain 100% of its mass almost all the time. Some cases of a petal breaking off do occur.
• Copper will often not expand quite as much as lead core but the expansion seems to adjust based on the range to the tgt so that it always penetrates enough to result in a good kill.
• Animals shot with copper TSX do not often result in a "Bang Flop" result. Some minor tracking may be required.
• Copper works well when breaking bones is needed to reach vitals like with some of the African PG and DG animals.
• Lead core often expands more violently and dumps more energy in the first 8-12 inches of the wound path. That may or may not be a plus depending on the angle of penetration and the size of the prey.
• Copper TSX type may not be better, only different and either type works when the hunter places that good first shot.

One thing I do with TSX type bullets to insure good results it that regardless of caliber, I limit my shots to ranges that will deliver the bullet down range at a minimum speed of 2000fps to insure that the copper bullet will expand adequately. This is usually around 400y for most. I also limit my shots from off sticks to those ranges that I can confidently shoot with accuracy. For me, that works out to about 300y max off sticks. And then I try to get closer when I can. This varies with the animal, terrain and cover. But, usually I can get to 200y unless out West on the open plains. I practice at much longer ranges out past 400y with my hunting rifles so that a 250y shot feels like a chip shot most of the time. Most of my rifles love the Barnes ammo but like others stated, they do like clean bbls.

When I clean my bbl, I do not use a copper solvent. What I do is clean the chamber with a carbon solvent and then lightly polish the bore with a very mild polish like KG-2 Bore Polish followed by wet/dry patches using only the carbon solvent. This removes the copper fouling from the surface of the bore but leaves it in the micro-pores of the steel surface. The result is a very smooth surface on the inside of the bore and also delivers a very accurate and consistent cold bore first shot. Finally, before hunting, I fire one or two of the cartridges I plan to hunt with just to burn away any residual oils or solvents from the bore. I learned this method over time as a competitive national class precision rifle marksman and former national champion shooter. It is excessive attention to detail for hunting alone but it gives me the confidence to take shots quickly in the field when necessary.

Now this I can believe. It makes a lot more sense than just a belief that switching to copper bullets will make a rifle more lethal. Sometimes they work well and other times lead is still better.

Maybe I would have had better results with copper bullets if I had gone through the intensive cleaning procedure that you described. I can't say I've ever heard of a specific carbon solvent or KG-2 Bore Polish.
