PR QT .40 235 gr
 

Has anyone had any luck with this bullet? I can't seem to get better than 3"@100yds. I am shooting 209 primer, 2-50 gr clean-shot pellets, and this bullet out of a 50 cal. 700ml. Also, recovered sabots are bases only - no petals on fired sabots remaining. Any suggestions?

PR's bullets usually provide excellent accuracy, as long as they are matched well to the gun. And that may be the problem. You would probably get better results with the .45cal QT in the 300gr range.

Your powder could also be the culprit. I love the CleanShot loose powder, but I've heard a lot of complaints about the pellets and their inconsistancies. If you can, try some loose powder with your 235's and see what happens. I would start shooting groups of 3 with 80gr of powder and work up in 5gr increments. My Knight is sighted in with 348gr Power Belts with 110gr of loose Cleanshot, and each change of 50grs of bullet weight necessitates a 10 to 15gr change in powder charge. So in order to shoot your 235 out of my gun, I would have to drop back to around 70gr of powder & fine tune from there.

Personally, I think the larger bullet will solve the trouble faster than dropping the powder charge.

Thanks guys. I think I'll try the loose powder first. If that does'nt work -then up the wt. of the bullet. I did'nt like the pellets much anyway. There is not near a tight a fit with the pellets as is the powder. I'm shooting this afternoon, I'll let you know how it goes. Any thoughts on the fired sabots? Or is that inconsequential?

ewc,

Post-mortems on sabots are somewhat inconclusive. I've heard people say that the smaller diameter bullets tend to spread the sabot petals out further and also carry them further downrange before seperation - all of which would be very bad for accuracy. Your loss of the petals might be an indication of excessive projectile speed which damages the petals, causing them to fall off once they clear the barrel. If so, the larger bullets would remedy this as they would slow down the muzzle velocity somewhat - depending on powder charge.

Shooting the loose cleanshot (78gr by weight) I grouped 4 pr qt 235's to 1 1/4"@ 100yds. Using the same wt of powder, I also grouped the 215's and the 250's to about 2-3" out of a dirtier barrel. I'm sure I can group any of these bullets. I guess it was the pellets causing the problem, not the bullet. Thanks for the help.

EWC.YOU WILL HAVE TO INCREASE THE POWDER CHARGE TO AROUND 110-120 GRAINS TO IMPROVE ACCURACY FOR THE QT'S 40'S

F.V.A. HOPE HE IS NOT USEING A POWDER SCALE

I weigh my powder on a scale. I have found that volume measurements vary as much as 3%. This way I have exactly the same amount of powder in each load.
