22 Dasher fireforming

[brfun]

Hello.
I am looking for suggestions for fire forming loads for a 22 Dasher with either 50 or 75 gr bullets. I have some H380 i would like to burn up if possible if not I also have Benchmark, Varget, W748, N133, and some old H450
Thank you!

I use 29.5 gr of Varget with a 80 SMK. You could see what load of H380 matches that. Good luck!

I've only used 55 grain moly plated Nosler Ballistic Tips for fire forming, all while bombing prairie dogs.

Most were with around 30 grains of VV-133 or H-322 with the 55's. With mine being moly and you wanting to use naked 50's, I'd start at 30 gr. and sneak up from there. These powders are too fast for a formed case, but work well for fire forming loads. It seems to build pressure fast, so go up in 3 tenths increments.

I shot 37.7 grains of H-380 with the moly 55's at 3700 fps in the formed cases. For fire forming, I'd try one case at 33 grains with the 50's and see what it looks like and go from there.

Good luck,

Al

Thanks guys!
I was thinking close to 33gr H380 for the first twenty 50gr nude bullets then going to 75s and moly for the reminder at 30gr of H-380. Doesn't look like was to far off track. Just trying to use up some old components for the fire forming.
Looking to shoot either 75 or 80gr Berger's molyed after the fire forming I was going to try H4350 for my load development. I am supposed to pick up the barreled action today from my gun smith and going to try and skim bed it this weekend. The scope should arrive Friday so with any kind of luck I hope to get out to the range next week sometime.
Thanks again!
