I shoot a 22" NEF Sportster and S-14 Contender in 17HMR. My Sportster w/ Hornady ammo chrono's right at factory spec, the 14" was 2475fps...as you say, not much difference. Accuracy is great in both witha slight edge to the Contender. Could be the most accurate factory barrel I've ever had at 100yd, on a calm day. Hornady shoots so good I never bothered to try another brand. The Crows around here don't care much for it. Fred at Bulberry has a good barrel length/velocity comparison on his website. GOOD SHOOTIN', Walt :grin:
