escopeta2020 - Looks like your Shilen shoots pretty darned good with Lapua in its EPS chamber. All but one of my custom 22RF bbls have been chambered with my PTG EPS reamer, including five Kriegers, two Shilen ratchet rifled select match, one 3-gr Benchmark, and a Lilja titebore, and they all shoot pretty well with SK & Lapua ammo. However, a couple of times last year while testing some Eley Match, one of the Kriegers and a Bartlein that VGW chambered shot better at 200+yds with the Eley than they did with a select lot of Lapua Center-X. I was mostly just shooting up some lot samples of Eley that I'd bought to try in an Anschutz 2011, but once I found out how well my V-22s liked a few of these lots, I wondered if the Lapua & SK would perhaps shoot better at the same 200+yds if they were chambered with a reamer designed from the get-go for best performance with Lapua? I may do some work to find out when I get my hands on a V-22S action & get it set up to shoot BR. I have a Shilen ratchet in R5 contour for it, and may try either a Bartlein or Krieger for it also - unless the R5 shoots lights-out, and if it does, why mess with success?
