All:

Okay, I have an FN Mauser which was built by the W. Brenneke company, chambered in 9.3x64 Brenneke.

I have shot probably 50 rounds through it in the last month, both TSX and Barnes solids, without a problem.

All of a sudden yesterday, I started having feeding problems. Almost always with the second round (magazine holds three). The cartridge would jam against the front of the third round. Once the claw extractor failed to engage the rim on the first round.

So I was thinking the 'usual suspect' is a weak follower spring, so I ordered one from Brownell's.

Thoughts and advice appreciated, thanks.

Check make sure the follower is not hanging up/
If you have had it out, you may have put the spring or follower in backwards or it is not centered in the box.
