Hammerli 215 feed problem

Very frequently, the second round in a magazine loaded with 5, fails to go into battery. The slide pinches it before it is completely free of the magazine. Same with several magazines, same with different brands of ammo. Cleaned and lubed gun and mags to no avail.
Only happens with the second round in a loaded mag.
Any ideas to fix this?
Thanks!

I had a similar problem with a 208S and a nelson conversion. One pound lighter recoil springs fixed both.

Took off 5 turns of the recoil spring, then another 5. Still, no joy.
Some magazines fail less than others, so thinking I may have magazine issues.
Can't wait to try some new ones!
Still open to other ideas.
Thanks again Ric!

what are your feed lip measurements?

If feed lips are open to wide the cartridge can flop and not enter chamber correctly. The 2nd round could just be combination of feed lips and magazine spring tension/pressure. Typically tuning feed lips can fix your problem. What ammunition?

Hi Chris/Jon- 
I'm familiar with High Standard magazine lip measurements. Are they the same locations for Hammerli magazines? If not, could you refer to a drawing as to where these measurements are to be made on Hammerli mags?

Same results with CCI, Wolf, and Lapua Standard Plus.

I've never replaced the "recoil" spring over the passed 20 yrs. But... I've replaced mag springs  a few times with two guns.  Seems to fix the problem. cg
