Took my Interarms US MADE TPH .22 in Stainless to range on Sunday. Have not shot it in several years but cleaned and lubed it. Checked the forum for best Ammo. Shot both CCI Stinger and Mini Mags. I know that Stinger is hotter but had problems. The Mini Mags had no problems. The issue with the Stinger was that a first double action round would not fire. Rim showed a strike in rim. If I did a second DA pull or a single action shot it fired. Subsequent shots in single action were fine. Any recommendations. Forgot to bring box of CCI Quiet Semi Auto to see if it would cycle the TPH. Anyone tried this in mouse gun 22? Thanks.
