i thought i had my problems solved. I've got a knight master hunter that i've had for about 5 years. i've never had that great of accurcy with it. i've shot the barnes red hot 250, sbt 245, shockwave 250 superglide, 777 lose, AP loose, black box pellets, red box mags. i thought that i got it all sighted in great this summer. i doubled checked it yesterday and i was all over the place. no consistacy at all. will not hold a group at 100yds. i mean that is all over the place without touching my scope. low left, high right, low right. i don't understand how or why. everything is tight, stock, scope etc. why is this happening? what should i do? my season is next weekend. i'm half tempted to get a new gun. i clean the barrel after each shot.
also the blow back fouling is horible. i get a ton of residue coming back trough the breech plug, getting under my bolt gumming it up so bad that it's hard to close and this was after just 9 shots.
How does it load? When you push the bullet down is it snug or loose? Ml's take some pressure to load. Also 5 years is a long time. How many shots through the plug? I'd get a new one. Probably the 2 most overlooked causes of inaccuracy are loading pressure and a worn flash hole. Also do you use a bore brush? I find that helps with fouling. Are you using bore butter or oil?
i talked to knight today. this is what the guy said. I'm cleaning wrong. i clean with a solvent patch then dry patch then reload. he said i'm cleaning to much. i should only spit on a patch and that's it.
That's an opinion. I solvent patch too.
he said that a fouled barrel will shoot better then a clean one. so when i go out to hunt he said i should load up with a juck round, shoot it spit clean and reload with hunting round. that's hard for me to comprehend.
Fouled barrels do shoot better than clean ones but I refuse to hunt on a fouled barrel.
he also said something about the front scope base screw holes and the seating depth of the screws need to not be bottomed out. i don't get that either.
Some bases have too long a screw for the front hole (Weaver primarily). They have to be shortened by 1/16".The front hole is not as deep as the second hole. If the screw isbottomed out then the base could be loose.
and the last things is to help prevent the blowback i should screw in the breech plug itll finger tight (which i always did) then back it out about 1/2 to 1 turn to eleminate any headspacing that may occur on the other end witht he primer and bolt face.
sounds like alot of unnecessary stuff.
The flash hole being to large is usually the biggest culprit. I do understand the idea behind his comment but it's not neccisary.
EDIT: Forgot to add someting. Throw out the APP. That stuff is awful. It is extremely inconsistant powder.
