I had alot of problems with my Sendero SF2.
Purchased in 2009
Returned for chamber issues, would not hold zero
Returned for locked trigger adjustment screws
Finally got it back, correct.
I have shot one hole at 100 yards and 1 hole at 200 yards for a 5 shot group with my reloads, but I REALLY had to tune the load in.
I suggest you buy an action and match grade barrel and have Montour County custom rifles
put it together for you on a nice H&S Synthetic stock.
You will spend the same money and have a great rifle without all the BS I had to go through.
has some very nice Zeiss 6.5 to 20 x 50MM scopres too - Rapid Z reticle in 600, 800 or 1,000 yard versions. Floor models at great prices. I got a Vermint reticle and have killed a good amount of chucks with it.
