TSX vs TTSX in 243

[andyk]

I’ve been doing a bit of load development for a lead free hand load for my 243. I’ve tried both the 80gr TTSX and 85gr TSX.

The TSX is considerably more accurate, not that the TTSX is bad. 3 shot groups with the TTSX are a shade over 20mm and the TSX under 10mm.

That leaves me looking towards the TSX. However, I’m also putting some thought towards which expands better as I’d tolerate the worse groups if the bullet performs a lot better.

Does anyone have any first hand experience of either? Even if not a side by side comparison, experience with one or the other would be appreciated.

Cheers.

Its likely a twist issue vs length of bullet.

Drive them fast enough and they should perform where it counts, but if I were to choose a copper bullet from scratch, Id go with @Virtus Precision UK or @Yew Tree Fieldsports

Buy British.

Yew tree is the king of bullets lead no lead whatever

Load 80gr ttsx in .243 tikka. N160. Under 1/2 MOA perform perfectly.

Thanks guys, it’s just that I’ve got a reasonable number of each, so deciding which to stick with.

My inclination is the TTSX as the accuracy is more than good enough and most things I’ve read say it expands better. I just thought I’d canvass opinions in the hope of being told the TSX works just as well!

I have used both the tsx and ttsx side by side in other calibers and the both work as well as each other.
If you have load worked up for both shoot one then switch to the other once you have run out. Thisbis what i did and saw no difference.

at that difference its not going to matter , what i should do considering i assume these are 100 yard groups is TAKE THE RANGE OUT SOME , you might well find one offers less wind or one looses the plot 300 yards say ? i have a load anyone would run with at 100 yards , as 150-160 its waaa so-so but at 200 its not worth taking much effort because we are talking minute of dinner plate !!!! while other loads keep 0.5 or moa at that range in the same rifle . Terminal effect would also need looking at ( i assume its for live quarry ) . TSX and TTSX marked boxes are confusing because the Nomi culture is messed up TSX can be polymer tipped or not TTSX are tipped but then it might be different in production age , whim or caliber , really dont know ( someone wants a word in their ear to sort this out ) boxes have TTSX on the side and TSX on the lid , could not make it up really

I’ve been using the 85gr TSX in .243 for two seasons. The only complaint I would have is blood trails tend to be less obvious than with lead. I consider deer shot with this bullet die faster than with my previous lead load with chest shots. I wouldn’t go back to lead in any calibre. I do use a TTSX bullet in 270 and it works equally as well as the .243. Both are very accurate.

80g TTSX using IMR4350 43.5 Grains (powder no longer readily available) in my Sako .243 knocks down roe to big stags.

Thanks all, maybe I should just try both then.

I think your problem is common. Perhaps buy some ballistic gel or use some other method such as water bags, large plastic milk bottles and wads of news paper. While in the relative infancy of lead-free ammo we are all trying to derive mor facts on terminal effect/capability that was seen as a given with lead ammo. We are probably more critical than we ever were of lead ammo!
