i use both the 290 tez & the 300 gr expanders tez's i use for long distance & expanders @ 50 yrds or less both have worked well for me
however the buck i shot @ over 100 yrds acted as if i missed it ran about 60 yrds & piled up.never really expanded well but did it's job & put him down. my son had the same problem about 2 yrs ago shot a doe & she gave her death call but never recoved deer.had a ton of hair & very little blood.
