Need some help with bullet search

[artjr338wm]

I've been looking for a bullet suitable for use in my 45 caliber Knight. Specifically a bullet of .400ish diameter that will still work in a Harvester smooth blue sabot that weighs anything between 225 grains but doesn't exceed 300 grains.

I don't at this time wish to spend the money on the equipment needed for resizing bullets so I can go sabot-less.

Thanks,
Art.

I will throw you a curve but i know several guys shooting385 paper patch hard lead bullets with extreme accuracy up to 1800 fps . What twist is your knight45?

[7mmfreak]

I will second the paper-patch and I know for a fact the Green Mountain .450/.458 barrels with 1-30" twist will shoot up to 425gn bullets if you go that route. At least mine will; those are full bore, lubed lead not paper-patched.

Is there a reason the 195gn Barnes (that everyone loves in the SML) won't work for your purpose?

Knight 200 gr Bloodlines

Thanks for the suggestions of PP/lead bullets, bit I'm planning on using max charge of BH209 so a all lead bullet will likely not work at those MV's. I eas hoping someone knew of a copper clad expanding bullet 325 grains or under made for say a .404 Jeffry or .416.

I was reasonably sure such a bullet doesn't exist but wanted to know for certain by asking here.

I have been considering the Blood Lines, has anyone know their performance at 300 yards?

[bestill]

300 yds and a 200 gr bullet at appx2200 fps is not going to perform well on deer. Might want to run ballistic numbers on that load . And wind will be game breaker.

North Fork makes a 300gn .411" soft point

[artjr338wm]

Thanks again for the info. I susppected Northfork might make a bullet that
possibly might work, but I could not recall their name, thanks for solving that problem for me. Was hoping to get in the mid 2300's with the bullit of my choosing using a heavy charge of BH209, will make use of a friend's recently aquierd chrono to be certain of my MV

Its going to take100 gr by weight blackhorn to reach 2400 fps and updated breech plug with carbide bushing to handle flame cutting. And make sure your knight is a bolt gun. Plugger gun wont like these pressures. And full plastic jacket will leak terribly. Go with bare primer setup for sure.

[lakeplainshunter]

84 gr by weight (120 gr by volume) of BH 209 will just get you to 2300 fps with a 200 gr bullet. I am not sure that I want to shoot another 16 gr to bring it up to 100 gr by weight.

Thanks for the data. My Knight is a bolt action Extreme that has had it's bolt updated so as to eliminate the need for the red primer jackets. It also has the BH209 compatible convex BP sold by Knight.

Will this set up safely handle 84 grains measured by weight of BH209, without suffering flame cutting? I don't at this point wish to go with so heavy a change of BH 209 to force me to by a special BP.

Thanks again,

The convex plug is the old style bare 209 primer plug. The new one has a Lehigh type vent liner brazed into a shallow pocket. The old convex plug did not work well with BH209.

Ooops, my bad. Meant to say CONCAVED as you pictured with the VL permanently installed. Thanks for correcting me.

[bestill]

Gun will work great and new plug will also eventually vent will burnout then you can replace vent liner. Good machinist will be needed to remove old one and thread for new liner then good to go.

I have shot up to 91 gr by weight of BH 209 without any issues. The recoil got a little harsh and accuracy was not as good so I dropped back to 84 gr by weight. 84 gr by weight always shoot better for me that 77 gr by weight.

[artjr338wm]

Thanks again 84 grns max it is. Will of course work up to it. Also will order 3-4 back up BP from Knight.

First, i am not a machinist. However, i have managed to remove three of these brazed vent liners. What i tried to do was learn a better way each time, however the last one went about the same as the first one even though i changed my procedure. These projects dulled several of my tools. The brazed in vent liner is very hard, very hard. Chances are i will never remove another, but one day i may attempt the task again.

Have you a nice clean way to remove the brazed vent liner?

[bestill]

Carbide end mill 4 flutes in Bridgeport mill with coolant

[ronlaughlin]

Thank you for the information. The end mill beats anything i tried, and should allow me to remove most of the brazed vent liner. Then i guess i would use a 3/8" carbide 82 degree spot drill to finish the counter sink for the new vent liner; would you?

Wow, that was some fine shooting you did today at friendship!

[bestill]

Yes 82 degree spot drill exactly rite

[ronlaughlin]

Thank you for your help!
