Groupings? HELP!!!

But Barnes cartridges cost $38/box. You might as well be shooting Weatherby's.

I went to the range yesterday. I found some Hornady !30 grain Interbonds and compared them to the Hornady 140 grain SST. I had cleaned my rifle with Hoppe's Elite and Shooter's Choice copper remover.

After a fouling shot, the Interbonds shot a 3 shot 1 5/16 inch group. The SST's then posted a 3 shot 1 7/16 inch group. I thought I had found my bonded elk bullet. But the next groups went to pieces. The Interbond had to 2 shot groups that were 5/8" and 7/16" but the 2 shot groups were part of a 4 shot group and were 2 1/4" apart making a 2 9/16" group. Next group for the SST's was 2 7/16". So I shot another Interbond group trying to concentrate and reduce errors. I got a 2 11/16" 3 shot group. The next SST 3 shot group was 1 5/16". I decided to shot one last Interbond 3 shot group. It came in at 1 3/8".

WOW! I go from great to crap to great again. I wonder why? I was trying to be consistant and I watched my sling swivels so they didn't contact the sand bag. No real wind.

So that's my lastest report. Which would you use?

Thanks in advance, TJ
