Still working on potential loads for the 38 gr Wildcat in my CZ527 American. Tried 5 round groups using 27.8 gr W748 and 26.7 H4895, CCI 450 primers, Winchester cases.

It was a bit breezy on the day I was testing, making it tougher than usual, but for some reason I'm getting flyers after the third round.

Do these results suggest barrel heating? (The barrel didn't seem terribly warm to me).

If the flyers are always 4th and 5th shot you sure would think it is heat. Try a longer spacing between shots to see if that helps. I usually wait 60 seconds from a shot untill I load for another and if I wait a few minutes between groups I don't have heat issues untill over 20 shots or sometimes 30 have been fired.

I would say heat. The other thing I've seen folks do is not make certain the rifle is on the same place on the bags every time in a string. If you are waiting a minute or two or however many be sure you wait with an empty chamber & keep your loads out of the sun. HTH

Hey CV. Is your 527 the light sporter barrel or the varminter?

Its the sporter.

Yes, it could easily be heat related. You have a light barrel and they are more susceptible to heat drift.

My Ruger No. 1 starts to spread out after three shots, possibly after two. I end up with two touching, and the third by itself. So long as I shoot three shot strings, I can usually cover them with a quarter at 100-yds. The fourth would take a 50-cent piece. If I shoot a fifth, it's out at about three inches. Always moves up and left.

Thanks, guys, I'm going to load some more and try them a little more slooowly.

I don't really want to sound too stupid but I'm fairly new to the 204. What is the 38 gr Wildcat and who makes it?

Thanks Gube. I'd be interested in seeing what kind of results some of you guys are getting with these. Dave
