Don't let the "there's too many Angus out there" crowd get to you. If your bulls are good, people will come and people will pay for them. The only thing the overpopulation of Angus cattle is going to do is weed out the subpar cattle.
As for selling your bulls, we routinely sell 30+ bulls out of our yard privately and average around $3500.00. We pre-price everything and advertise through local classifieds, breed magazines, and online. We feel it gives us more control over price and far less overhead than a sale. You need to be prepared to carry over a couple bulls in case they don't sell though.
XBAR - As for the comment about getting twice what the animal would bring for the ring: Do you mean as a commercial calf? I won't sell any purebred bull for less than $2500 and generally I put my lowest price at $2800. If the bull won't sell for that, I'll happily turn him into hamburger. I think half of the problem in the purebred business is people flooding the market with cheap, below average bulls. With all the work of performance testing, registration, AI, promotion, semen testing, and guaranteeing the bulls I can't stand to see guys selling bulls for $2000 or $1800. All that does is train the commercial guys that they can find cheaper bulls if they don't worry about quality.
