rustypic,
I have a Krcio M603 in .243, which was recently re-barrelled with a 1:10" twist hunting barrel(23.5"). The rifle is slightly lighter than a featherweight, but very similar in design/configuration, so similar to use. A mate has a featherweight from the mid 1980's in .243.
In my Krico, I've been using 87Gn V-Max Hornady projectiles. They have pretty good ballistics, fly well, and hit hard for most small-medium game. The fact that both Hornady and OSA load this same projectile in their factory .243 ammo lineup, probably means something...
I havent got my load data to hand for the 87 V-Max's, but I think it's at the top end of the recommended load range for AR2208.
I've used the 95 Nosler Ballistic Tips in front of 33.5Gns of AR2208, and absolutely no complaints, but the slightly lighter varmint-style projectile in the V-Max and the cheaper price, suited me...
These days, I dont get to shoot the Krico that much, but the 2 projectiles I bother to keep loading are the 87Gn V-Max, and the 58Gn V-max (for varminting).
The 58 V-Max is departing around 3800fps behind a load of 42Gns of AR2208 (ADI), and they are laser-straight for about the first 250 metres.
[NOTE: No doubt teaching grandma to suck eggs here, but dont use anyone else's loads without verifying them, and best to start at the recommended starting load for your powder manufacturer. I'm just supplying them to give you an idea of what I've been getting out of my rifle.]
Another note: When my mate (who owns the Featherweight) worked these loads up for me, he focused on a loading that was delivering the best groups, so he didnt even get around to checking them for speed. Of all of them, the 95BT's were the tightest grouping, from my recollection. I think they ended up being one ragged hole at 100m, which was pretty amazing for the ho-hum trigger on the Krico.
