Default Range repot Barnes TTSX 130 grain .270 load test

Came by some Barnes TTSX 130 grain in .270 in case the need would arise to have a lead free bullet.

Tested the bullets seated at .010, .057, .099 and .115 off the lands in a Parker Hale 1200 with a Nikon ptostaff 5 mildot scope off the bench at 100 yards using reloader 16 powder.

Seat. Spread. Closest two. Vert. Spread. Horz. Spread
.010. 2.5". 1.3". 1.25". 2.1"

.057. 2.25". .88". .6". 2.5"

.099. 1.62". .85". .5". 1.5"

.115. .75". .47". .5". .5"


Found the trends interesting. Was going to chronograph the load but the chrono went tango uniform at the range this morning. This is pretty much opposite the data for the Speer 130 boat tail which like to touch the lands for the best accuracy.

This is also opposite from the TSX 140 grain bullet which shot best when seated about .040 off the lands.

Moral of the story seems to be generalizations about seating the "new" copper bullets far off the lands will hold true in some weight bullets but not for others even though the bullets would seem to be similar even when fired from the same rifle.

I am a fan of the old Nosler Partition bullet, but I did experiment with the Barnes TXS bullet in an accurate 35 Whelen I own. Like you, I found accuracy was very dependent on seating depth, more so than with any cup & core bullets in that rifle.

That might be a big factor with those who have reported poor accuracy with Barnes solids in their rifles.

I have shot both Speer and Nosler ballistic tips with great success. With the newer ballistic tip nosler has changed the bullet profile and bullet length slightly making my old bullet seating data pretty much out of date.

I am going to do some work-ups with the "new" ballistic tips and want to give the 130 accubonds a try as well. With the Nosler partitation being a shorter bullet they should well from the old .270

I assume "spread" is overall group size?

You are very right about generalizations; every gun and chamber is different. I've found some Barnes TSX bullets need to be seated way out for best accuracy in a particular rifle, in sharp contrast to suggestions in the Barnes manuals. Some shot best seated quite deeply in other guns.

Correct.

Spread is the overall group size, closest two shots than horizontal spread and vertical spread

Same here, Nosler Partitions are old school just like a nice S&W revolver. Both still get the job done all day long and twice on Sunday.
