338 lapua improved/should I leave well enough alone

[Tyler Kemp]

I shoot 300gr Berger/SMK/285 Hornady ELD and 100gr Retumbo. But I seat long and single shot. I've went to 104gr and that's where I found pressure..and almost 3200fps. I have a 32" Broughton barrel with canted rifling. 100gr is about 3050 with SMK, 3025 with Bergers.
