I have a good supply of 200 grain Wildcat bullets waiting for my new 7mm Allen Mag and I just couldn't stand it, seeing them sitting there, and waiting for the new gun, so I tried them in my 7mmWby.
I talked to Richard about them and he didn't think they would stabilize in my gun but curiosity got the best of me and I went out this afternoon and shot a ladder test at 300 yards using the 200 grain Wildcat ULD RBBT bullets in my factory barreled 7mmWby.
When I do a ladder test I always load 3 extra of the lowest load to get on target with. These 3 lowest went into 3/4" at 100 yards. So far so good and they all cut normal round holes.
Then I moved the target frame to 300 yards and did the ladder test. I honestly expected to see some really funny holes at 300 with these long, heavy bullets being shot in a 1-10" barrel, but at 300 they all stabilized and all went through pointy end first.
I was using WC872 and as expected the nodes were better in the upper range of the test. The big Wildcats were seated .020" off the lands. I only tested up to 103% fill, but the grouping looked a lot better in the upper ranges, so I will probably try bumping it up a little more later.
For now I will take the best looking loads and load up some for test groups. I will also test these at longer ranges before trying hotter loads.
I am curious to see if they will still stabilize and shoot at longer ranges. This is in a 1-10" twist barrel and Richard felt that 1-8" would be better. Sometimes you just have to try things to see if they work. I am not saying they work great yet. I will reserve that until after I see what they do at a little longer range.
I can tell you one thing I noticed as soon as I started shooting them. I had shot some 169.5 Wildcat ULD RBBT rounds just prior to trying the 200 grain rounds and I can tell you that the 200's really disturb the terrain when they land.
If you've got a 7mm and are interested in the big 200 grain Wildcats, give them a try. They just might work. /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif
