[bushwackr]

Hello all does anyone have the swift load data for 200 a frames, and 180 scirricos for the 300 rum that could be emailed. I checked all my usual places and no book available.

I just purchased the Swift#2

Retumbo 87.4 - 94
H1000 90.7 - 97.5

200 Aframe

Retumbo 87.4 - 94

Swift scirocco 180gr / retumbo / fed 215M

A healthy load of retumbo at that. Work up and watch for pressure but my accuracy load was well over the 94gr max.

I think it a bit odd that the retumbo data mentioned by Scottishcat uses lighter charge weights than the h1000 data, as retumbo is a slightly slower powder... Must be a rifle dependent thing... I'd guess most rifles could eat a bit more retumbo but the Swift data is what it is... tread lightly I guess.

Ya I'm also unsure what swifts load data is but I was also surprised by the low data numbers due to every other book I look at shows a much higher max load for retumbo and the 180gr pills

I find it surprising myself so much so I looked again and what I posted is what is written in the Swift #2. 24" wiseman bbl, Rem 91/2M Remington cases.

Hogdons data say's 94 to 100.5 with a sierra 180 and a lesser amount with H1000. The Swift#1 does not provide data for the 300 Remington Ultra Magnum and Retumbo so this data is new.

The data for H1000 in the Swift#1 and #2 remain unchanged. I suspect a change in testing parameters or a typo. I have not heard of any changes to H1000.

I would contact swift and ask them [email protected] or just start at 92 and work up 1/2 a grain at a time.

Good luck and shoot straight.

I have the first book and it was sort of trashed by water I believe so not all the pages are clear and I guess it's time to order the new one anyway.
How is it the two retumbo loads for two different bullets and weights are the same? that doesn't make sense to me.
Also does the Swift #2 have reloader in there as well?

That's interesting as well especially after review of RL data. Drop them an email they respond well.

For the 180 SSII

RL 19 80-86
RL 22 84.2-90.5
RL 25 87-93.5

200 AF

RL 19 74.4-80
RL 22 80-86
RL 25 81.8-88
