Yep, sure do! I have a good friend that is runnin 120 grs by volume in a 28 in TC barrel. He dropped a doe at 206 yds with 3 witnesses to prove it. Pittmans shoot great out of his 1-28 barrel probably even better out of your 1-20. When it comes to muzzleloader bullets I think if the good lord intended anything else to be better he woulda kept em for himself! He was also shooting MMP high pressure sabots and 250 gr Pittman .452.

I also have the CVA scout conversion. I want to run the parker bm 275s. What is the max load of bh 209 you can run. Will it handle 90 to 95 gr by weight. This is for an elk hunt it took me 18 years to draw. I can't use smokeless in Utah.

Mt Dutton tag in Southern Utah. I was also wondering how much if any adding a nurel to the bullet affects the BC. The parker BMs also seam to push through with almost no force without any sizing.

This is for an elk hunt it took me 18 years to draw. I can't use smokeless in Utah. For my shooting i usually call it good at 95grW of bh209 as ive seen very little fps gain per grain above that . However according to pressure traces youll Never overload that Scout conversion with bh209 . Load away !!! As far as knurling goes i prefer the accuracy and the fit to keep that bullet on the powder than any minimal bc effect honestly . First things first for that --Keep it on the powder !!! Youll be fine as i cant see any difference knurled or not in their flight . No effect of any real consiquence on bc that i can tell . The polywads are a good idea too both for weather sealing and powder burn . Both dam important on a hunt . Good luck on your hunt !!! |

I was getting 2250 fps w/95grn by weight BH209. This gun shoots the parker BM 275 amazing. I put my last 2 shots in 1inch at 200 yards one clean bore and one dirty. I would put this gun up against most rifles for accuracy I had it zeroed in 5 shots. Next to no kick. I'll take it out a few more times to insure I have a perfect cold bore shot. Thanks for the help. |

If I had waited 18 yrs to draw an elk hunt I think I would have taken that time to develop a solid copper load. Just me. I would want serious penetration on a big elk. All angles made possible with a hunk of copper that would not frag on a big bone. Just me.

Youre more than welcome . Youre also a man after my own heart . I make sure my loads shoot on a cold clean bore to Exactly where i want them to land !!! This IS the most consistant bore condition for a hunt . Some may argue that but let them . Clean is Mean . It doesnt change , only temps affect it . With a good knurl youll never see that either . Good luck and shoot a Dandy !!! |

All angles made possible with a hunk of copper that would not frag on a big bone. Just me. I can't say that I disagree with you, but the bore on the rifle is no as true as I would like. When pushing the bullet down the barrel I noticed the bullet is tight for about 4 inches and then loose then tight. I knurled the bullet so they engaged. The thin walled parker expands when shot making it more accurate. I did try the ELR but they hit the target sideways at a hundred yards. I have a friend who has shot multiple elk with parker BM through both shoulders. I shot multiple elk with a white 45 cal shooting 460 grain all lead no excuses. I bought this gun to shoot farther than the white, but my plan is to keep close, accurate, and deadly. |

Do you, by chance, have a bulged barrel?

No, from what I understand it is common with the CVA barrels.

No, from what I understand it is common with the CVA barrels. Most all production barrels leave alot to be desired honestly . This is why lapping a barrel is done to get the bore concentric from end to end . I dont know if your bore is coated or not . If not i would consider this as a option for you in the off season . Every production rifled barrel i have has been lapped . They all have been made tack drivers because of that concentric bore too as well as pretty well tooling mark free . Figured i mention this is all in case you may be interested one day . It seems a fluted barrel with a button rifled bore or a hammered one is more likely to have this going on in unevenness in my experiances . Seems like the steel relaxes in there when its done expanding a bore from residual stresses . A unsaid common thing i think . A cut rifled barrel isnt so prone to this . Myself id rather just get a slimmer contour and save more weight but its not as stunning to the eyes . Of course thats a custom job not needing lapped either . The slicked up barrel pretty well free of tooling marks too sure stays/gets clean alot better and longer too . That in itself is really nice . Loading feel is greatly smoother too . I cant help but think the bullet seals far better afterwards . Its a winner to me . |
