Has anyone experimented with knurling bullets not so much as to increase diameter but to give a better grip on the sabot for stabilization?

Yep, the 195 Barnes is generally more accurate when knurled vs unknurled. Most think it grips the sabot better in a .45 barrel.

In my sabot days my best groups came from knurled Barnes290 tez in supplied blue sabots in a Remington geniuses with90 gr blackhorn. I definitely think thekknurl helped grip and also allowed me to get fit i wanted. I also indexed sabot to rifling to be consistent shot to shot.

Right after converting the 10MLII to .45, a guy sold me experimental bullets that Knight had special ordered from Barnes. He got them from an auction Knight held here in Iowa. They were 150gr BX shaped just like the 195's but shorter. Supplied sabots were the brown MMP's, and I could not get them down that tight barrel, so ordered the Blue Harvester's.
Some of the bullets with BH's were fairly snug while others went down one handed. This is when I realized that few Barnes are actually .400, .451, etc. Groups were around four inches.......looked like I was using buck shot! Prior to going to the range again, I measured all bullets and knurled them to just under .401 which made for tough two-handed loading. Groups shrank drastically to sub-MOA. Prior to going sabotless a couple years ago, every Barnes bullet I used got knurled with very good results.

I understand if your knurling for size you roll it pretty heavy. If you just want a better grip on the sabot how much do you need? I have been experimenting with a file and rolling over an oak block for shooting the 50 cal. How heavy of a file do you normally use

I use two double cut files, one on the table the bullet sits on and hold the other. If one were going to knurl full size bullets the tool that Jeff is going to sell would be great, no worries about broken file chips imbedded in your bullets, a barrel trasher for sure. not a big deal for sabot shooters but a no no for full size shooters...

Watching for the knurling tool with great interest! If he ever gets them into production. Just from what I saw in his commercial it might help if the amount of pressure on the bullet was adjustable? It may be I could not tell in the pictures?

For a light knurl i use a file and a sheet of hard pressed felt on the bottom.

It may be I could not tell in the pictures? There is an adjustable stop between the two handles. I'm sure that Jeff will get these made when time allows.

Kyle. Thank you I could not tell in the picture. I got a feeling quite a few people will be interested.
