Sorry about your loss.
A lot of people brag about the accuracy of both models. But, I suspect it's a toss up that may come down to the individual rifle. Either way, they should both be sufficient for 700 yds hunting and playing at 1k.
I own a Sendero and other Savages and like them both.
I have held the 111LRH, but haven't shot it. My impression was that it is a little lighter weight overall. The built-in muzzle brake
doesn't look to me as if it would be as effective as several after-market models. I really like the Accutriggers.
Sendero has a heavier barrel and I suspect it would do better firing 20 round strings at 1k. But, I doubt it matters for cold-bore or for a 3 shot group. I would probably be looking to add a brake and replace the trigger unless the newer ones have the x-mark pro.
They're both good shooters. So, I don't think you'll be disappointed.
