New to reloading, just did my first batches of pistol to test out. Going to list info on the loads then explain issue.

115gr Xtreme HP with TG powder

OAL 1.090 as specced in Lyman

Powder charges 1 set at 3.8 other at 4.0

124gr Xtreme HP with TG powder.

OAL 1.14

Powder charges also 3.8 and 4.0 gr

Shooting outside at about 40-45F


Shot the 115 @ 3.8gr first. Fine

115 @4.0 squib, right at start of rifling in the barrel. Came out fairly easy. A couple cycled then squib every time, right as bullet got fully into the rifling, no further.

124 up next, both sets 0 issue (fired really nice).

So I was confused as hell. Assumed maybe I labeled them wrong in the box. Came home, grabbed a few more of each 115gr load. Went to indoor range this time. NOT A SINGLE ISSUE!!!

Seems my scale was off on calibration because the 4.0s I could tell were firing a bit soft and not grouping for shit. Actually neither was great, but 4.0gr load was noticeable on recoil.

But what's got me is I didn't think it was cold enough to screw with my case pressures that much. They keep it at like 68 at the indoor range, so 20ish degrees.

Any insight, be great if someone could give me a break down because my Google foo is sucking for this issue.
