Coated semi wadcutters

Has anyone else found that the coated semiwadcutters don't cut the nice clean holes that straight lead semiwadcutters do?
Possibly the sharp edge is just being rounded by the coating and they are losing the cutting ability, or could I not be loading them hot enough.

I frankly can't tell the difference.

Can't tell difference but use mine on steel so there is no hole.

Any diff is minimal & vel would have nothing to do with the hole in paper.

Which coated bullet manufacturer have you shot that has a minimal difference between them and lead bullets. I will be going to the range tomorrow and will post pictures of the difference, lead cuts a hole that looks like a paper punch, COATED semi- wadcutters holes look like they were shot with round nose bullets.

The 175gr 40 from Missouri. It's not a perfectly round hole, but its still a cut hole vs a punched hole from a RN. Since I shoot steel or cardboard IDPA, I am happy using even RN.

YES, coated bullets do lose some of there cutting edge!!
Reloading

I'm guessing I won't have to explain which are straight lead semiwadcutters and which are coated semiwadcutters.

Boy, you weren't kidding, with holes like that, kind of hard not to justify just loading RN.

I use Bear Creek Supply molycoated LSWC in .357 and .452 and Speer coated LSWCHPs in .357 and all make nice clean holes in paper for me. I've used uncoated LSWC and really can't tell any difference in the holes.

Precision Bullets 200gn swaged and moly-coated SWCs cut very clean holes. The old MasterBlaster cast and moly-coated bullets cut very clean holes.
Thus, coated bullets, per se, are not the problem. The particular coated bullets you have may have a problem.

Do you have a picture of these Masterblaster holes?
I truly wanted to lose the smoke and keep the holes but this isn't happening.

MasterBlaster closed several years ago. Not sure I have any pictures of the groups. Used the 115gn 9mm L-SWC from MB and, if I had known they had any possibility of closing, I would have bought as many as I could afford. At the time, I was testing bullets from various companies and found MasterBlaster and National Bullet Company bullets were excellent (the NBC bullets were no pretty, but they were very accurate out to 25 yards any way). By the time I was ready to order more bullets, both companies had closed.
Are the shoulders on your bullets sharp or rounded with coating?
Many companies are jumping into coated bullets and many might still be on a learning curve.

That was the point of my posting, I believe that the application of the coating has taken the sharp edge off the semi-wadcutter and hence, I have lost the advantage of nice sharp holes.

I have some coated and uncoated LSWC 125gn bullets. The coating definitely softens the cutting edge of the bullets. The difference is apparent on paper.

Thank you Smokey45, I am not beating up coated bullets, I really do enjoy reloading and shooting them. I have found a recipe for some coated flatnose bullets that are incredibly accurate in a 9 MM Range officer, I was looking for something as accurate and a nice clean hole when I discovered that the coated semi- wadcutters just didn't cut the holes my lead ones did. I do like the fact that all the smoke from the lube is gone.

I'm a fan of coated bullets and will continue to use them. I still have about 4k that I coated in .40 and 9mm. I like those clean, full diameter holes, but sure don't miss the smoke!

Sounds like it has a lot to do with the quality of the coating.
