Does anybody have this setup? If so, what loads have worked with the 40gr "ballistic tip" bullets? What velocities? What do you think is the ideal barrel length? TIA, R303

Rule, While I don't have a gun in this caliber, I can recommend an article in Handloader by Steve Timm where he worked up loads in a Kimber with a 24" inch varmint bbl with 12"twist. If you want, e-mail me and I can give you more specific info from the article.

I have a .221 rifle that I had made up on a Remington 600. I had McGowen rebarrel it with a medium-heavy 1-14 twist 21" barrel.

I had trouble picking a barrel length, so I just doubled the 10.5" length of the XP-100. Pretty scientific, huh?

It made into a cute rifle after I restocked it. It looks kinda like a 7/8 scale African rifle.

Anyway, here are some of the better loads. They aren't as small of groups as the ones Steve Timm shot while at Kimber, but I only have a Leupold 1-4x scope mounted.

1- 12.0 grains of Accurate arms #9, 50 grain Sierra Blitz, Federal 200 primer. 7/8"@2622fps.
1A-11.5 grains of the same powder, all other components unchanged brought group size down to 7/16 to 1/2 inch. Velocity 2540 fps.

2- 21.0 grains of WC846 (surplus powder), 50 grain Sierra Blitz, Fed 200. 15/16"@2848fps.

3- 17.0 grains of IMR 4198, 50 grain Remington softpoint, Rem 7 1/2 primer. 1"@2835fps.

4- 14.4 grains of IMR 4227, 52 grain Speer HP,Rem 7 1/2 primer. 15/16"@2793fps.

None of these are earth-shaking groups, but not bad for a 4x scope. They really aren't much different from my XP-100. But the rifle is so much easier to shoot, and almost as handy.

Please notice the changes brought about in loads 1 and 1A by varying the powder charge by .5 grain. That goes to show how sensitive the small case is to change. It ran pretty typical regardless of powder used.

I see by my records here, that the last time I did any work with that rifle was in June of 1993. Hmm, maybe it's time for some more.

Sorry I didn't include any 40 grain bullet loads. It's because I didn't try any, not because they performed poorly.

I wanted to try some back then because I had some reservations about 50 grain and heavier bullets in the slow twist barrel, but I couldn't get my hands on any.

But I have some now, though. Ballistic tips and V-Max both. Leftover from a K-Hornet project. Which didn't work out too bad, But didn't offer anything the old Hairball didn't.
