Curiosity Test.. Brake VS No Brake and Expander VS No Expander

[Thumper580]

Wondering if running my brake had an effect on accuracy and also whether using a neck expander or not effected accuracy. My data set is very small, I understand that, but was wondering what the results might indicate... Results are 5 shots each at 100 yards.
Equipment:
Tac Ops XRAY-51 .308, ZCO 5-27 scope, Alpha brass, Berger 115 flat base target bullet, CCI small rifle primer, VV N-135, 44.0gr. 2.190 ogive, @3025 fps. SAC modular sizing die, 334 bushing, 80 degrees, overcast, no wind.
Results:
Left side is no neck expander with 4 port Hawkins brake and with no brake.
Right side is using a 306 neck expander with the same brake and then with no brake.....

Assuming all things being equal... Not using the neck expander with No Brake appears to be the way to go. At least with my equipment. 5 shots measuring 0.097".
Tiny data set, but interesting to me.

Yeah it likes the mandrel and with the neck done doesn’t really care if there is a brake. Or just shoot without the brake

The best group was no expander and no brake. I'll shoot that combo again and see if it hangs in there.
