I have owned my Crown in .25 since 12/27/17 and so far am pleased with the Crown, gun is accurate, has been trouble free and has so far lived up to all the hype.
"AWCG"Mine arrived last Thursday and I’ve put two tins of JSB .30 44.75 grain pellets, and a handful of NSA 66 grain slugs down range.
So far my gun is on point. Stacking pellets at 45 yards, and just over an inch pattern at 100 yards.
The NSA slugs are not engaging the rifling as well and have some wobble. At 109 yards they have opened up to about a 4 inch spread. Same spread I was getting from the JSBs at 175 yards today.
It may be the most accurate gun I own.
If I look at the slugs I think those are primarily made for hunting. The length and shape ratio of the slugs are not ideal for long range projectiles. You might be able to get them to group tighter than the 4" it's doing now but I don't think you will be able to achieve 1MOA at 100 yards."AWCG"I was using NSA 66 grain, .30 slugs. FX is making a barrel sleeve just for the NSA slugs with a faster twist rate and I believe a more aggressive rifling. I’m going to stick to JSBs until the new sleeves are available.
Just put in the order for a new barrel kit (.22, currently have a .30 on the gun). AoA says they should be available in April. No word on when NSA specific liners will be in."broekzwans"

But please post your findings here as soon as the barrel arrives I think more people are interested in these projectiles
