The 270 Savage, and the 270 Titus, were long ago answers for 250s with bad bores. PO Ackley, whom I knew personally, did quite a few rebores to both these calibers.
The 270 Savage is the 250 necked up to 270, and easily gets 100 gr bullets to 3100, 130s to 2900. The Titus is the 300 Savage necked down, and with its greater case capacity gets about 100 fps more.
The 99 action works for either one, and Ron Smith is able to do either one today. His price was just over $300 last year, bored and chambered.
