That seems short to me. I am using a 135 TC (truncated cone) from another brand and the OAL is 1.130. Thousands of them have been used in an HK P30, but I also use the same load in a G19 and a PCC AR which uses Glock mags.
Maybe try 1.100 or 1.120 and see how that works.

What kind of differences in accuracy have you observed in rifle loads? Is the difference in 100 yard groups or further out?I don\’t know what Jake would say, but I have tried the Lee FCD on the 69 3GH and it did not seem to make a difference.
Post that Jake, the owner of RMR made-

+/- .003 is not going to matter much in most applications.
The variation could be because of a couple of things, not just the seating die. Bullet and neck tension variation, press tolerances, and compressed loads can affect seating consistency.
More testing shows that neck tension definitely helps. I\’m currently at 2.260 OAL and 24 grains of TAC. Next I am going to try 24.5 grains.
Yes, it is on my batch as well. I\’m currently working on load dev and will be shooting them tomorrow.
My last test groups were 1.5\” and .21\” They seem to be sensitive to neck tension. The .21 group was with more tension.
If they plunk test then you are fine. The throat on the Wilson gauge is probably shorter or tighter than your barrel, and interfering with the different \”ogive\” on the truncated bullet.
