Hello: I bought some Lapua 260 brass for necking it up to 7mm for 7mm-08 loads. According to my reloading manuals, 260 and 7mm-08 brass are 2.035" in length. The brass that I received all measure 2.018-9 in length. Is this normal for Lapua brass to be this short? This is my first using Lapua brass. Thanks in advance.
