Blackhorn 209 and sabotless loads

[doulos]

Interested in smokeless but really intrigued with sabot less rifles. Anyone using Blackhorn 209 for sabot less loads?

 

[GM54-120]

Yes, and sofar it appears to work just fine. My best results have been with thin jackets and softer lead cores such as the Parker BE and Sierra 458 300gr JHP. I size the Sierra down in 3 steps to fit my bores. The Parker needs only 1 step.

84-91gr by weight works for me. A little less if using a 250gr bullet.

At the range I shot the 460 gr No Excuses bullets behind 90gr of BH209, also using a fiber gasket. I've gotten good preliminary accuracy, but am a little worried about how easy the bullets go down the barrel. It seems possible the bullet could shift off the powder with a good bump, and everything I have read tells me BH209 likes to be compressed as much as possible.

90gr...ouch. I stopped at 80gr with big lead.

For big lead, size them .001 to .0015 over land to land and you should not have a problem with them moving off the powder. I checked the little 451 350gr over several days which included lots of walking. It never moved. My bore is very slightly under .450

I shoot a custom fast twist 45 and blackhorn with sabotless bullet. Extremely accurate .
Keys are proper breech plug for blackhorn and hot 209 primer, snug fitting bullet seated firmly on powder with a veggie wad.
I use a sized Parker bullets or hornady sst or hornady ftx. You will need a adjustable sizing die to obtain proper bullet fit with different bullets.
Imo it takes a 100-120 gr by volume load to swell thin jacket bullets.

thanks bestill, Thats what I was asking about. I should have been more clear in what I was asking. I was most interested in sabot less jacketed bullets . But thanks for all the replies.
