Was thinking about trying BH209 powder in my Ultra Mag but thought I'd see if anyone has had any issues or tips to pass along?
Sideshow maybe do a video of you shooting 120 gr BH209 by volume out of your White and put detailed description in it showing what you've done to your White.. 120 gr by volume of BH209 would be very dangerous in a regular plunger style gun so if your going to recommend it might be best to show what you mean.
It is damn hot in a 410 !!! I didnt recomend that load . Lets be CLEAR on THAT !!!!! It IS a overload , i realize that and so do you . I TOLD you that !!! I'll see what i can do on a video . Computer genius i am not nor a movie maker !!!Sideshow maybe do a video of you shooting 120 gr BH209 by volume out of your White and put detailed description in it showing what you've done to your White.. 120 gr by volume of BH209 would be very dangerous in a regular plunger style gun so if your going to recommend it might be best to show what you mean.
The Whites are heavy tank tough so the recoil isnt that bad IMO . The nipple and lapping in the plug make it possible to ignite and seal it with the barrel . It is NOT a White breech plug , 5/8 x 18 , and has a lehigh vent liner . I use permatex thread sealant with ptfe(teflon) to seal the threads as well .The bore is sealed by a 410 shotgun wad trimmed and used as a sabot with a 330gr home made bullet of .388 diameter . I compress the powder and the bullet to 75lbs . I use Federal primers . My actual powder load is weighed @ 85 gr or if you prefer 120gr by volume , close enough . Its under MOA @ 200yds and its FLAT . Its earned its name of "Mighty Whitey" . Thats 1 load . A .002" oversized conical load of 400 gr or more will be developed as well . I know i cant make it nearly that hot . Bullet wont take it . The 410 is 1 in 16 twist . It too will be a blackhorn load . I can thank Busta and GM54--120 for that tech !!!!!Still like to see 120 gr by volume of BH209 shot in a White, not twisting anything just asking you to show us a video of it being done, especially would like to see it done in a BK-92 of which Ive owned a bunch of and there's no way on this planet I would even try it or consider it. You say you've done it repeatedly so it would greatly benefit all of us to see a video of it being done and a short tutorial on how its done to ensure we do it safely!
I don't have a BK, or a White (yet) and never saw one in person. Do you use this in it with a scope? If so how in the world do you get in there to unscrew it?
I looked at it but to me that thing would be hard to access in an MK or LK with a scope in it. It looks like the only reasonably safe way to shoot BH in a Plunger gun. For me it just looks like too much trouble to save on cleaning. Just to shoot on the bench it would be ok, but can't see it in the field. Just my 2cents.
