Polishing feed ramp to smooth out feeding?

[King_beardsly]

Has anyone polished up the feed ramp on their actions to smooth out the feeding from the magazine? I'm getting some hang up running the bolt home, i checked the mags and they seem to feed smooth in an other rifle I run, now i dont know if its the feed ramp is causing the drag or possibly my choose or ammo.

More details would help
What action are you running?
What cartridge?

I am going to guess.... Stiller Tac30?

Sorry I thought I mentioned that, but I guess is forgot it. 6creedmoor feeding from MDT metal mags into bighorn origin action

Ugh... why did you mention my action. I have had a couple of issues with Prime 6.5 feeding in mine

I have taken a dremel to both my Defiance actions at the feed ramp. I grind them down just a little to better match up with the mag and feeding. I was also getting hangups and since i have done this they feed amazing. Defiance Tactical, 6.5 creed and 6SLR, MPA chassis, ARC and Accurate mags.
I ground them down then went to polishing them smooth. Scary the first time but after that no issues.

Hmmm..... wonder how I guessed.... they are not the smoothest action. Strong, yes. Smooth? Hell No.

I'll have to give that a try, maybe adjust the ramp angle just a tiny bit.

Yeah that is all it took for me, it seems like there was just a little lip on the action underneath the cutout of the chassis. My main issue is that as I would get low on a mag with maybe 1-2 rounds left the recoil would cause them to push forward in the mag, then when I would go to feed a round it would not take because it was caught. I simply etched it away and have not had an issue since, I did this on my Defiance with the XLR chassis and Accurate and AW mags and now my other Defiance with MPA chassis and ARC mags.

You can see in the picture where it was overhanging from the magwell, rerouted the feedramp in the middle.

I must have gotten lucky. My Stiller is very smooth.
