How far can I expect to shoot with this load?

Re: How far can I expect to shoot with this load?

Thanks. Ok so another question. I was measuring my magazine at lunch and it looks like I have plenty of room to increase my COAL. I never did jam a bullet in the lands or get any closer to the lands than my .020" off the lands when I did my first testing. This .020" load was far better than any of the others, so I'm thinking that I will load a few more up with a few jammed maybe .010" - .005", a few just touching, and a few maybe .005" off the lands and see where that gets me. From what I've read these vld's like to be jammed or touching the lands. What do you guys think?

I think that if you jam a bullet into the lands and don't shoot that round, when you eject the round you are as likely as not going to have the bullet stick in the barrel and strew powder everywhere as the cartridge case spins away. To be able to seat a bullet so that the ogive consistently touches the lands you will need a bullet comparator. I have this same issue with Berger VLDs and I just ordered a Hornady Lock-N-Load comparator set from Midway.

Just as a side note, my Ruger .270 win will only shoot VLDs well when they are loaded touching the lands. If I move 0.005" off the lands the group size more than doubles. But this varies from one rifle to another.

I didn't think of that. So what do you think about me try a few loads from .005" off the lands, .010" off, .015" off, and my allready tested .020" off and see which one groups the best? Then I shouldn't have any problem with the bullet sticking in the barrel right?

It can't hurt to try things. Typically a bullet with a tangent ogive is not very sensitive to seating depth and a bullet with a secant ogive likely will be sensitive to seating depth. There are exceptions. I don't know what bullet you are shooting.

A couple of other things to remember about seating touching the lands is that pressure goes up exponentially under this condition. You will need to back off your powder charge two tenths of a grain or so if you try loads with the bullet touching or jammed into lands. Then you can work back up to where you were if there are no pressure signs. I don't know your level of reloading experience but remember to trim cases so that you don't get raised pressure from a too long case neck being crimped onto the bullet because it was forced too far into a chamber.

Read this first before you waste a bunch of rounds. I'm working on a new load for a 30-06...Re 17, 190gr Berger and things are looking good at .110 off the lands.

Don't jam the bullet in a hunting load!

Thanks for that. I'm shooting the 168 Beger VLD Hunting bullets, so they do have a secant ogive. I am fairly new to reloading, and yes I do plan on always trimming the cases to the correct length.

Thanks again. I started at .020" off the lands and went up to .080". I need to just start over and do exactly like that article said. It did seem like the futher away from .020" I got the bigger my groups were getting, but who knows. I need to find out for sure so I'm not taking wild guess's. I've got a Bass Tourney this weekend so I doubt that I'll make it to the range, but I will post my results once I make it out. Maybe I'll take off early on monday.

Re: How far can I expect to shoot with this load?

This is my VLD seating depth test. The center is the touching the lands. The upper left is the 0.005" off the lands group. The other groups are further from the lands. Granted there is a flyer on the center target but subsequent testing showed the touching the lands loads to be the best for accuracy.
