Re: 1/66 turn conicals
I use the Hornady Conical and\or the Buffalo Ballett. They are essentially both the same.
Now, on the Hornady's I clean out a lot of the lube that come's on them. IMHO Hornady just over-does the lube on these things. So, I will sit with a small screwdriver and a piece of terry-cloth and clean out all of the back of the Conical's and give a quick wipe of the excess on the outside.
Now, that being said (you don't need to do this with the Buffalo's) I load 'em over 100gr. Goex FF and I always put a T\C bore button in between the powder and the conical. I do this as I believe (no proof...I just think) that it prevents any excess lube from infiltrating the powder, and I also believe the bore buttons provide a "cleaning" when loading the next conical.
Now, the Conica's do slide down the tube really easy. When I first began to use these I double checked 'em all the time to make sure they were seated. Especially when I would have a long walk, or go up a rough hill. However, I've never had a time when the conical had "fallen" away from the charge.
But, that's been my experience. I have a trust factor in them in my gun now. If you switch to these, check 'em until you build a trust factor. That's the best you can do.
I find these provide a better blood trail than the PRB. I've hit deer before with a PRB and had NO blood trail, only to find them 100 or plus yards they were full of blood.
I think the Conical's give a larger entrance wound....thus....give me something to follow. But....that's just my opinion.
