Very interesting TSX vs Nosler!

[FOTIS]

From another site....

A friend of mine told me of a test that he did with the 270 win and the 300 win mag using TSX, AccuBond and Nosler Partition bullets. Both rifles are sighted in the same. Both rifles can hold groups right at 2.5" @ 350 yards, all were 3 shot groups.

In the 270 win it shoots 140 TSX @ 3030 fps and 140 AccuBond
@ 2975 fps. At 350 yards the 140 TSX is 4.5" lower than the 140
AccuBond.


In the 300 win mag it shoots the 180 TSX @ 3050 fps and the
180 nosler Partition @ 3015 fps. At 350 yards the 180 TSX is
8.0" lower than the 180 Partition.

I would have not thought that this was possible with the hi BC of the TSX bullets, are they slowing down due to the rings? Has anyone had results like this with TSX bullets?

I saw this on the 'fire too. I believe it.With the published BC's for the TSX bullets I am surprised it is not more of a difference. The new MRX bullets still arent that much of an improvement in the BC category,but may help with the lack of expansion some see.

It depends on where he zero'd. I'm thinking if both loads were zero'd at their useful range.....say 250 yds there would be very little diff in flight path out to 350-400.

BTW--the tsx bc is not nearly as high as originally published.....from what I am reading from others experience it is thought that the "bands" on the middle of the bullet are really screwing up the bc and lowering it.....it isn't the fact tha its a hollow point.

To get those big diff's in trajectory I'm thinking he's zero'd at 100 yds otherwise it doesn't make sense. Also.....are both bullets equally accurate. If the gun shoots the noslers more accurate they will be able to maintain the bc the manufacturer publishes.....if the tsx is not as accurate it will reduce the bc quite quickly.....a wobbling bullet has poor bc.

I've seen tests where round nose bullets that are more accurate in a gun will hold the same bc as a spitzer that isn't as accurate right on out to 300 yds.

If you look at the Barnes web site, they had to re-figure all of the TSX BC values & they went down alot & yes the grooves make a difference. They just came out with some plastic tipped TSX bullets (no I don't mean MRX) & this will raise the BC for those, but they still may be a little short of AccuBond.

From the research that I have done, bullets will "print" in different spots on the target due to different harmonics on the bullets. The real question is what is the drop difference in drop if compared between round fired at 100 and 300 yards ie shoot the TSX at 10 and 300 measure the drop, shoot the AB measure the drop and compare the two. I know in my 350 rem mag the 250gr (about 2450fps or so, never chronoed)speer printed about 2" higher that the 225 TSX (shot @ 2620fps) did at 50 yards! but at range the 225 showed less drop. See what I'm saying???

I think Barnes has "cooked the books" with the BC values, they are not as high as cliamed for the TSX bullets. I also "think" the rings in the bullets act as a drag and slow down the bullets. Just MHO.....

My experienced with TSX was quite different. I'm 3 inches high on my 100 yard zero when compared with my old standby 180 grain Hornady BTSP from my 300 WinMag. I can get 3000 fps with the starting load of 74.5 grain of IMR 7828. Using my Exbal Ballistic program, the .505 BC is dead on... at least up to 600 yards. The accuracy of these bullet are outstanding. Good for elk or bears but way overkill for deer.

I find that the accuracy of the TSX in my 350 to be outstanding 200yard 1.5" 3 shot group, I'll live with that, overkill,there is no such thing as overkill if it puts meat on the table.

I think it all comes down to what you are hunting for and how you can get them to shoot. I love the accubonds but cant get them to shoot well out of my gun so I swiched to the TSX and it shoots tight groups and shoots flat. what else can I ask for? Also I think it unfair to compare a all copper TSX to an AccuBond. Isnt that why nosler came up with the E-tip to compete with Barnes???

Now all I have to see is how they work on my sheep and elk hunting this fall.
