Not much has changed for 5mm fans the better in the last 11...considering pellet availability and the number of 5mm airguns for sale, it's gotten worse.

And shocking really. I'm sure glad they did it, they are capable of a BC in the top 5 of everything that JSB makes, up to and including .25s and .30s. I've measured BC's for them in the same 0.045-0.049 range that JSB reports. That's at around 915fps, their BC is down around that of the JSB 18.13 in .22 (about 0.035) when going <870, at least from my gun/barrel. I almost wonder if some crazy haired JSB engineer/technician made them as his/her own little side/pet project and was surprised to find how well they shoot so they ended up being manufactured. In fact, I had a really fun shooting session a few weeks back with the .20 Heavies at about 93 yards. Shot 5 of the condensed EBR practice cards (5 targets per card, 5 shots per target) and had 4 or 5 sub moa, 5 shot groups. And the sub moa groups were on the bull, not off in no-man's land. A couple were around 0.7moa and the others were just under at about 0.9moa. Long live the .20!!! (and I don't think Crosman's going to play anytime soon)x2 the comment above, keep buying them, and they'll keep making em

Scott: In a way, your last post kind of helps sum up the state of 5mm’s. MOST of this long string of posts are from 5mm fans that already have a 5mm and already have a stash of 5mm pellets.For a new guy, who has the itch to try the 5mm, but has to start flat-footed today, it’s not going to be cheap or easy.1. Are no “entry level” 5mm’s (lets call that sub $500 for a PCP).2. Crosman is NOT going to come to the rescue with a cheap drop in 5mm barrel.3. Are some few high priced/semi custom rifles….likely not real attractive to a new shooter who just want to try the caliber.4. Few would want to spend the $$ to custom LW re-barrel (and whatever bolt adjustments needed) just to try at 5mm. Even DIY, likely cost me near 250% of the QB cost back then….would be more like 50-70% of the cost for something like a new M-Rod.5. Even if you did buy/make one, starting “flat footed” buying pellets today would be frustrating. The 5mm fans shooting 5mm are doing it from per-bought pellet stashes.To be honest….as a new guy with budget limits….I’d pass.
LOVE my .20's and see no reason why one would make the gamble on an unproven barrel to save likely $50 or so ( Even tho Crosman does not make a .20 ) The LW or HW .20's shoot so dang well it is a case of buy once and ENJOY !!You can have a low cost / quality air gun shoot very well !!! .. reason for shooting very well would be the BARREL being the most important part if seeking accuracy potential.
