Default VLD chamfering 17rem cases

So I bought one of the VLD chamfer tools and used it on some 17 rem brass. I noticed right off that the bullets loaded with almost no resistance. There was zero bullet brass scrapings to which is what I was trying to stop.

My question is how much velocity loss would be expected if any with less tension on the bullet?


Im going to crony them in a day or so but just curious on thoughts

Same load in new brass using the old RCBS chamfer runs about 4000fps

Not sure what the difference will be. I would hope that the biggest difference will be a reduction in the deviation. In other words, greater consistency. Let us know.

Just because the bullet is easier to seat doesn't mean there is less tension on the bullet. If less brass is scraped off there is probably more tension. Larry

Can't answer your question, but I've read numerous times that the Lyman VLD tool is the go-to tool for the 17 cases. I've always used the RCBS, but I started hand loading on the 17 Rem, so I don't know any different. When I can get ahold of new Rem brass again, I'm hoping to buy the Lyman tool to see what all the fuss is about.

Keep us posted... I'm curious if you see a difference in speed or such.

Are you chamfering both inside and out?

I have both. My RCBS is a little more aggressive cutting.
The Lyman taper is blunter, if that is the right term.

The VLD tool sourced and sold by Sinclair does a great job.

I have the 17 VLD from Sinclair also, and it works great. As I recall, the VLD tools are designed to put the shallow chamfer on the case mouth to make it easier to seat the long taper BT bullets.

Custom Reloading Tools sell a good one.

K & M Precision is one of the better ones out there. It is adjustable to do 17 cal. up to
.243 cal. I've had mine for several years still does a good job.

The feel you have now is less resistance due to not scratching/ cutting the bullet as it starts to enter the neck, like Larry stated.

So now with the VLD chamfered neck, the total surface contacting the neck is maybe .020" shorter than before you chamfered them with the new tool, so if you want the same "resistance" seat the bullets 0.020" deeper, lol.

Have you ever seen velocity changes between seating variations of say 0.060" ?If so, I would be surprised.

Now your bullets are not marred as they were before when you had a lesser chamfer, they now should be closer to smooth and I would suspect the only difference you might see is a more accurate round. The rings and shavings we see from not using the VLD tool are a direct indication we are/ were wrecking the bullet. I hate paying $30 a hundred for custom bullets and then scratch them up with poor reloading practices.
