One thing I believe I’ve learned about shooting sabots is that my bore will allow me to use a variety of sabot sizes, with a difference in the effort it takes to seat the sabot onto the charge. In two separate calls with two different CVA reps I was given slightly different diameter of my Accura bore. I got something a little different than that when I talked to the folks that sold the gun.
It seems ”might” be somewhere around .499-.500-.501. I was told that the bore on my Accura is considered a tight bore and that BarnesT-EZ 250 gr. Would be a good start. I shot a dozen or so of them yesterday at 25 yds. To get on paper. Compared to the effort I’ve seen folks needing to seat their bullet the T-EZ seemed quite easy to manage with one hand.
I switched to a Hornady 250 gr. SST to begin sighting my scope at 50 yards. For whatever reason, the accuracy of the Hornady was significantly better than the Barnes. However, I noticed that seating the Hornady was as easy to seat as the Barnes, if not easier. I guess the biggest boo-boo I made on my first day is that I did not clean my 209 breech plug. Needless to say, I suppose that’s why I had dirty primers and a lot of powder residue in that area. Lesson learned.
As for the easy seating sabots, I suppose I could have experienced far less compression in the bore than needed. Is it possible that if the sabot is too loose that it allows part of the compression in my charge to escape and contribute to the residue in the bore or around the breech plug?
Harvester is sending me a sample of bullets with a smooth black sabot to try. I’ve seen where Thor (?) has a set of bullets used to find bore diameter, or I can take the gun to a machine shop equipped to do such measurements. Anyone else find the same issue in an Accura? If so, what sabot did you switch to?
I understand from some readings that tighter compression of a sabot in the bore can improve accuracy. If true, how significant is the improved accuracy? Lastly, when looking for that middle-ground sabot that is neither too loose or too tight, how will I know if I’m trying to seat a sabot with my ramrod that is just too tight to be forcing down the barrel?
