Barnes 120gr TTSX Average Penetration (inches): 17.2 Average Weight Retained (grain): 119.2 Average Weight Retained (%): 99.3 Average Expansion (inches): 0.547
What's not to like here? As uniform as they get, and basically the only weight loss is the tip. I'd like to see them launched at about 3300fps and see the results.
Thanks for all the work Steve. Why? Seems pretty perfect already.

Yup, that's your problem, just make multiple posts. Bigger TSXs act the same on real game (35 cal 225gr 35 Whelen) Deer, Elk, Moose 338 Federal Elk, through both shoulders then into dirt bank.

Thank you for all the hard work. Hopefully this will be a sticky.

Same as the first test. The impact velocity was made to duplicate modern 6.5X55 loads and .260 Rem at 100 yds. Cast bullets were approximately 1500fps.
Approximate impact velocity: 85-100gr.............2850-2900fps 120gr..................2750-2800fps 125gr..................2600-2700fps 129-130gr............2550-2600fps 140gr-142.5gr.......2500-2550fps 156-160gr............2400-2500fps 168gr..................2300-2400fps
1. Thanks for all the hard work and sharing with the rest of us... 2. slow and heavy shows some pretty impressive penetration results.... 3. the 85 grain HP Sierra will show much deeper penetration if the MV is slowed down more...and more weight retention.. 4. the Reason the Sierra Game Kings won't load is that you have probably reached the file size limit with your other pictures.. just start another with a response mode..

Interesting. Looks like the A-max faired better than the Berger Hunting VLD.

Seems like you put in a lot of effort and expense, once again thank you. I have 6.5 x 55 and I shoot it a lot. I have come to think that a 120 gr Barnes X is the way to go, if they shoot well enough out of the barrel. There is nothing you could not shoot in North America with that load, maybe the Big Bears, but how many of them are you going to shoot in your life time anyway?

Did the OP test any 130 Accubonds? Maybe I missed it but did see the 140 AB info.

No, 140gr AB only. I can't imagine the results being much different.

Me either, just a tad less to start and end up w/in weight. Thanks! Great info, part 1 and 2.

only one missing is the 100 grain TTSX @ 3000 fps Yes that and the 100 grain partitions and ballistic tips, which have both worked really well on pigs out f my 260. Great work with all the testing, thanks

I see in the first test that the plain jane inexpensive 129gr Hornady SP equaled or surpassed the vaunted barnes and nearly equaled the 125gr partition.
I guess my 20yrs of experience with that bullet in my 260 isn't a fluke.

No 100gr Nosler Ballitic Tip? That would seem to be a popular chioce for varmits and smaller deer.

Thanks, I enjoyed reading the results. If you decide to do any more testing I'd like to see the 100 ttsx, 100 partition ann 100 ballistic tip.
Do some 7mm next!

Accubond = faux Partition CT Partition Gold was the best. (they never made 'em smaller than .277 tho) I have a small stash of 30 and 33 caliber specimens. Awesome work BCSteve!

Indeed! UP! With a 6.5 Creedmoor almost completed, I'm taking a special interest. Anybody got anything to add?

bearstalker: Rem 700 SA, Timney trigger,Sunny Hill alloy BM,#2 24" Benchmark SS 8 twist, and Echols Shrike Edge. All the parts are with Alex Sitman (Master Gunstocks) in PA for final assembly and bedding. Not sure about scope and mounts yet but I have a couple of scopes over here to get it cranking....unless I buy something else.

It all looks great, fine and dandy but in the final analysis what does it all mean, truly, as it impacts an animal?
I've seen similar photos of expansion for more years than I can count and they all look remarkably similar.
Frankly I'm not so convinced that the expansion aspect is nothing much more that bullet manufacturers sales spiel to con the buyers.
Energy dump is another pseudo scientific gimmick wherein the manufacturer brags about his bullet being found "just under the hide" on the opposite side. Not my philosophy. If it didn't go all the way out and leave wound channel/exit hole that means to me inadequate energy.
In the final analysis bullet placement is paramount in success and that will be a heart, lungs, spine, head shot and not a gut shot or a rump shot.
Don't get me wrong. I truly admire the study here. It's great and shows a great affection for ballistics. I'm absolutely for it 100%.
Just want to point out that there are other aspects contributing of equal and probably more importance.
