Well got to shoot the new conversion for the second time today. The first outing was a bust as I have a loose bore on the cva. After speaking with the experts on doug's I learned a quick knurling will tighten up the bullet in the sabot & dramatically increase pressure. It took 4 shots to get it sighted in with the new scope. The first shot was at 2450 fps. After the barrel dirtied a little I was seeing 2500+ with the last 4 shots ranging between 2550 & 2570 fps.
This gun is quite the shooter as I shot a 4 shot group at 100 and they were all touching & 2 almost in the same hole (see pic below). I finished the day with 3 shots on a sign I set up at the back of the property at 187 yards. it was definately sub moa. I will stretch it out to 300 yards next weekend.
The sabots all opened perfectly (see pic) as I waited about 10 minutes between shots. Want to thank tar12 as he was alot of help getting me set up.
I can't wait to get my encore barrel in so I can send it off so both my boys will have a 300yd killin ML :grin: I guess I will be stuck shooting the 50 cal.

Steve now that you have the knurling figured out you can bump the N120 up to 62-63 grn with out fear of blowing sabots.This will put you in the 2650-2700 fps range. With a 200 yd zero you will have a hold on hair deer killing machine to 300 yds. I have taken it up to 70 grn @3000fps plus BUT would blow sabots all the way down to 35 degree weather and with as little as 65 grn of the N120.Personally I do not like shooting in hot weather as the dynamics are different than your actual hunting conditions.Now all we need is some tail gate pics!

Here's a group I shot at 187 yards (length of my back yard). I believe shot #3 was my fault as i felt myself flinch. Had a 10-15
crosswind. same load as weekend.
