357 sig feed problems

[newbedoo]

I just put a Tanfoglio 9mm comp barrel reamed to 357 sig in a 40 cal Tanfo limed II.
The Tanfo shoots great in 357, better then 38 super I think. The only problem I have now is that the first 4 or 5 rounds seat well in the 40 cal mags, then the next 3 or 4 sit nose down and the top one sits nice. When I shoot it the first one is fine then the next 3 or 4 porpuse down and will not feed then the last 4 or so feed great. I tried a lighter spring and it did not help. Any ideas?

You could try bending the end of the spring that sits under the front of the follower up a but, so there is more upward pressure on the front.

or go 38 SC I don't think the World Champion has any problems with feeding.....

sorry couldn't resist...like mrclean said....and which bullets are you using? they should be 9mm 124gr Round nose...
