Ok, so the tide is turning on lead. I’ve got about 70 Hornady 143gr ELD-x bullets left then it’s time to start loading some copper.

After watching a recent field sports Britain episode on copper bullets it was suggested that the Barnes LRX worked well in the CM. I know every barrel is different but the Barnes options I was looking at are:

TTSX 100gr
TTSX 120gr
LRX 127gr

I was just curious to know who has used them and results really. I have done some searches but couldn’t find a lot of comparisons. I know the LRX has a lower minimum terminal velocity requirement but obviously the 100gr is going to be run

My main quarry is roe, muntjac and fallow. With some foxes thrown in for good measure.

300yard max range.
 
I think they will all work. My guess is that the one that will work best to 300m is the 100gr. You will get MV of around 3200 fps. Inside 150m you will get a higher % of bang flops due to the velocity and hydraulic shock. They will be flatter but a little more affected by the wind. 100gr is plenty heavy enough for the species you mention.
 
Thanks for that. The majority of my deer are under 200 so I was thinking under similar lines.

I’ll probably work a load up of some heavier bullets for when I finally get up to Scotland.

“the 100gr is going to be running faster”

Your TV at 300m is going to be 2400 fps so the fact that the TTSX is very slightly harder isn't going to be an issue. I ran 100 TTSX in a 6.5x47 Lapua for a few years at similar velocities and it was a very good bullet for your species at your ranges.

lrx bullets all the way,I use them in 2 different calibres and they far out preform the ttsx.

I ran the 120 TTSX at 3400 fps and the 145 LRX at 3150 fps in 280ai. The 120 TTSX was better than the LRX for distance run after the shot. Everything shot inside 300m. I don't dispute that the LRX is softer and expands better than the TTSX but the additional velocity gained by dropping the weight by 20% gave the TTSX an edge.

Shots over 300m I would agree that the LRX would be a better bullet, but copper at those ranges is pretty unproven and the OP's question was for shots inside 300m.

In what way do they far out perform? And what is that based on, like for like bullet weights and velocities?

They open up at lower velocity. so in .270 say the lead bullet of choice would be a 130grn as a all round weight.with copper you a supposed to drop a weight class to get them to preform and shove them fast. In copper the ttsx bullet of choice is 110grn ttsx going out at 3150 ish to get the best performance from 50 yards right out to 500 yards. The lrx bullet of choice would be 129 grns so you are getting more hitting power in weight going out at 2950 ish so better barrel life and not as punchy on the shoulder but still preforms out to 600 yards and much better expansion than the ttsx. I also use it in the 7mm rm with a 139grn bullet and it’s great for sika as they are known runners. But saying that I tested the .270 with the lrx and they just dropped on the spot so it’s all good. If I could availability wise and twist wise I would use them in every calibre I have. The beauty about the lrx is that you don’t have to drop a weight to get them to work as they have a bigger cavity in them so that’s why think they are by far the best non toxic bullet on the market.

Wouldn't disagree with them expanding better at slower TV's, but the OP was asking about sub 300m and at that range a 100 TTSX is going to have plenty of velocity to expand and the additional velocity will give a higher % of bang flops out to 150m. LRX is a great bullet but sub 300m I would go with a fast 100gr rather than a slower 129gr. It comes into it's own beyond that range.

Your experience with longer range shots on deer with LRX is very interesting. What range have you regularly and successfully shot deer out to with them. An idea of shot reaction and average distance run at say 500m would be really interesting.
 
I've used the LRX on short range Roe, all have dropped on the spot. Mainly quartering chest shots, there is a fair amount of damage compared to my GSCustom copper bullets, but no more than my 120 gr pro hunters. No being run on a stiff load, just a consistent accurate one. Once I've run them out to distance on steel I'd be happy using the on deer at distance, assuming the accuracy remains good.

I honesty find them better than ttsx at any range,They just down right work once you get your load sorted and if you are shooting around the 50 yards to 300 yards they are just awesome.Hey I’m not one for saying I do this and do that and it was this far away but all I can say out to 600 they will still work without any issues if you need them to.

I might just have to work up loads for the LRX 127gr and TTSX 100gr and test them. See which works better for me.

Any recommendations on stockists? Or are we on a COVID bullet shortage?
 
I don’t think there’s a lrx bullet in the country left apart from some 7mm and .243 I know of. I would get a order put in and just wait that’s what I do. I order 400-500 per time twice a year so I always have plenty of what I need 👍
