the 180 partition will work well with your setup and distance of 300 yards. i'm tuning my 30-06 with 168 TTSX and H414 powder for hunting Elk this fall. one advantage of the triple shock bullets is they tend to like some jump to the lands and can usually be loaded to fit in the magazine and still have their best or very good accuracy, not to mention a little more speed because they're not real close or into the lands.

Dave, just an observation: I narrowed my choices with the 168 TTSX in my .06 to Re19 and H414. Both worked very well, but the Re19 held the very slight edge for me. 59.0 grains of Reloder 19, WW brass, Fed 210M primers seated .020 off the lands. The H414 was also a tack driver, but I had about 1/3 of a pound left and 6 pounds of Re19, hence my choice. I think in my rifle, the velocity was better with the Re19 also as the bullets hit higher at 300 yards than those loaded with 56.0 gr H414.

My second bear in BC was taken with this combo. The guide was very happy with shot placement and internal damage. It wasn't far, just under 100 yards, but I purposely placed the bullet square in the shoulder. The exit hole was about 3cm in diameter maybe.

Wow, you got a lot more powder than I did. Barnes listed max was 55.0 grains. My max was 57.7. 56.0 was sweet spot. My group at 300 yards was 2", me prone, using a bipod and a really dirty barrel. Since the Re19 was doing so well, I stopped messing with the H414.

Well I've shot a few groups the last few nights & it seemed like seating the bullets out to the lands did the trick. It pulled the group size down about a half inch. The groups are staying right at an inch outside to outside of the holes which suits me just fine on these bigger calibers. My load ended up being 57 grains of H4350 over a CCI 200 primes in a Remington case that was full lenght resized, trimmed to lenght, chamfered & deburred, and of course primer pockets cleaned & deburred. I have a stoney point gauge & measured the overall length I needed with the 180 & seated my bullets to just barely touch the lands & has no interference with the bolt closing. These are shooting at an average of 2770 fps with not much deviation. Thanks for all the replies. You guys are a great bunch & so full of knowledge & experience.

Meanwhile I'm still having fits with my 7mm & the 160 Partitions. I've switched to IMR4831 just because it seems to be a little more consistent than the H4350 was. I've been loading them in the 2900 fps second range but I'm going to try slowing them down until I get down to 2800 & see how they like the slower speeds. I may try some Retumbo or H1000 if I dont have any luck slowing them down with the IMR4831. I'm not really concerned about how fast they are shooting as long as I can hit what I'm aiming at. I'd like to be shooting faster speeds but I know it doesn't matter how fast it gets there if it doesn't go where it's meant to. So off to load I go......

Derek, can't say i've found a sweet spot, i've been putting more powder in and the speed goes up and acceptable accuracy stays about the same. i keep shooting more powder until i get a sticky bolt, then you have too much. 2 gr below this would normally be my max load. the manuals are very conservative to put it mildly.

i tested these bullets at 30 and 540 yards to see how they mushroom. at 30 yards, i place a piece of 7/16" particle board, gallon jug, 2nd board and then 6 more jugs, with water of course. found the bullet inside the 6th jug with a perfect 4 pedal mushroom. at 540 yards, i just lined up jugs without any boards. i wanted to see if the bullet would open up. it completely penetrated 5 jugs and was against the 6st jug. again with a perfect 4 pedal mushroom. i wish i could post a picture showing the 2 bullets, they look exactly the same.

Why can't you?

I sent an email to Barnes back in 2003 stating that a TSX with a plastic tip would be a near perfect bullet and asked if it was even on the drawing table. At that time, it apparently was not. With the random issue of the smaller diameter TSX bullets not expanding, the addition of a tip seemed to be the next step.

Personally, I have had no negative experiences with any TSX bullet at any range, unless you consider death a negative experience. I suppose it was for the animal.

I have a LOT of TTSX on my shelf as I think their price will rise substantially in the next 5 years. At the present time, I would say I have enough to last a lifetime. They shoot very well for me. I also have a few Etips.
