This is a 60s or 70 Parker Hale [Spanish Santa Barbara] 30-06 that I rebarreled to 260 and re stocked.
It does not have any trouble feeding, but I have a Win70 243 and a Arisaka 300 Sav that have blocks inserted to make the magazine shorter. So the problem HBiC describes must be real, I have just not seen it yet.
The problem I have seen, and I hope I am not wasting your time mentioning it, is that the gap between the magazine and receiver feed ramp can catch a pointy bullet tip.
