I've seen some bad #1's..............270 and .25-06 a buddy had. Nothing worked.
My old B in .243 was a half incher at 100 w handloads.
My dad's .22-250 did good with handloads.
My RSI surprised me w factory stuff.

If I buy any #1...........I assume it might need a new bbl. I purchased my RSI just to rebarrel it.
But the regs changed here, the factory chambering became legal for deer..........and it shoots decent.

So off to find somebody cussing a #1, to score it cheap and rebarrel to .35 rem wink
