My 20 Extreme with an 8 twist Jury barrel can't shoot anything (reliably) under 40 grains. If they get to the target they are keyholed and it's more like shotgun patterning. I built it with the 55 grain Berger in mind and never considered that they would be discontinued and I would need to look for another bullet. A 9 twist would probably would have worked for them and may be a little more forgiving with lighter bullets but not sure. Fortunately the 40 grain Berger shoots just as well in that barrel.
Unfortunately for us up here there is a very limited availability of small caliber bullets. I get jealous reading posts with four or five different makes of small caliber bullets being mentioned, all of which are not available here.
