What seems like ages ago I began another one of my experimental efforts... It began with a discussion with Dave Fricke, owner of Lehigh Defense. We were generally discussing shooting full bore bullets and knurling them. He suggested the name of a German, Lutz Moeller, who builds bullets and the fact that some of his rifle bullets ride up the bore on very thing rails/barbs, quite different than we often think is necessary. After reading Mr. Moeller's thoughts and listening to Dave I really wanted to try the Knurling thing that a lot of others are into and ahead of me...

This thread shows/describes my initial attempt with knurling a full bore .500 cal x 350 grain bullet that Lehigh builds...

You can see that is was quite awhile ago that I accomplished the first part of the experiment. Yesterday I was finally able to make some time to go shoot the experiment. Between hunting season and coaching time became a crunch - in fact I believe I had more spare time when I was working than I do now that I am retired.

When talking to Grouse about this experiment one of his big concerns was how do you be uniform in the amount of knurling and the resulting diameter change of the bullet. I was really un-concerned until he mentioned it - then I began to really worry about what the results of the different diameters might mean in the terms of accuracy. Yet if Moeller were correct may not much at all.

Well yesterday afternoon became the moment of truth... I took my box of knurled Lehigh's to the farm, set up the bench and the chrono and got ready to work the experiment. So right away things go downhill... The battery in the chrono is dead and the spare battery in the battery compartment is not there because the owner operator of the chrono forgot to replace it that last time he need a battery!!!!

With the failure of that aspect of the shoot I moved the target to 100 yards and began the experiment... The rifle a Knight Ultra-Lite has already been sighted in with a .458x300 gr. Bloodline so I assumed the group location might change a bit but the group should remain consistent through the shoot.

And as Grouse had predicted... not all of the 15 knurled bullets went down with the same amount of pressure - none of them were loose enough that I was worried about the bullet coming off the powder in any instance while I might be hunting. Others took or needed a punch with a short started to get them through the crown. From that description you can see there was a wide variance in diameters, however most were loaded with just thumb pressure and a decent push down with the range rod. Really most felt like I was loading a bullet in a sabot.

During the shoot I did make one adjustment in the scope after the first 3 shots. After that everything pretty much went as planned. I believe the target indicates the variance in diameters really is not having a profound effect on POI from shot-to-shot. Also remember the powder loads are thrown on site into a volume measure... Also, remember that are better shots out than me and I am interested in hunting accuracy not as much as a one-hole group although I would take if I got it. I do very little fooling around with different powder loads to tighten a group. I just want the rifle to shoot what I want to shoot.

Yet in all fairness I know some of you could shoot this same rifle with the same load and tighten things up...



Remember I only had 15 bullets with me so these 6 shots on target were enough for me - I wanted to see thing break so I took out 5 orange elk hearts and placed them in the stubble in the field at 96 to 115 yards. Then I began to systematically shoot elk hearts. after I shoot the first three a friend of mine who has never shot a ML but is a big rifle shooter, asked if he could shoot one just for grins. He did then he did the second one and yet that wasn't enough he could still see pieces through the scope so I shot pieces until we ran out of bullets.

We are going back next week with a working chrono - I really want to know the velocity of the 350 grain GOLD bullets... cuz they sure shoot good!

What a report. Sounds like you had a lot of fun and maybe another ML convert to boot!

Bronc... you might be right he is already asking when we are going back to the farm...

Well done, very instructive!
Thanks

Hey Sabotloader, I've never gone sabotless but have always been curious about something. if you ever get the time would you consider satisfying my curiosity?

Do you by any chance have a bottle of Lee Liquid Alox? If so, roll up a single sheet of toilet paper into a tight ball and dip it in Liquid Alox. Prepare a few such balls ahead of time and let them dry. Then use them instead of Sub Bases for two or three sabotless shots and see what happens.

very nice shooting. Next time the chronograph will be an interesting extra.

I am pretty sure I do have some Alox... I will give it a try and let you know. It will not be next week but I will get it in...

It is suppose to happen next week... I hope!

So You also have joined the ranks of people who retired and do not have as much time to do what they retired to do in the first place. I haven't been fishing in 13 years going on 14 and that is one thing I wanted to do. Even have a brand new 15 year old fly rod and reel never been used.

Nice experiment. I've been kicking around the idea of shooting conicals to stop using sabots and pistol bullets.

A lot of my friends have suggested that I really have failed at retirement!
