Help with load data for the 55 Berger .204

Post by jam1e »

Hi folks,
I generally use 32's and 40's in my .204. But I've just got hold of some Berger 50's and 55's, and wanted to give them a go.
My problem is finding any load data. I've found some for the 50 Berger's, but nothing for the 55's.
Can anyone help with some data? I have IMR8208XBR, Hodgdon's BLC2, Viht N133, and Viht N135.
Thanks.
Jamie

Jamie, unless you have a fast twist barrel, your factory barrel is most likely a 12 twist and will not stabilize a 50gr bullet. Bullets in that range will require something like a 9 twist, and then your velocity will be then be something like a 223. There are much better cases for .20 cal heavy bullets than the 204R.

Save that valuable powder for the bullets you've been shooting. :D

Thanks for the reply Rick.
I bought my rifle as a 1 in 9, but have only ever used 32 and 40 grain VMax, which work great.
I do have a .223, but I don't want my .204 to replace it. The 50's and 55's, are more of an experiment than a long term plan. I only have around 50 bullets of each, and just wanted to try something different.
Cheers.

jam1e--the .204 Load Data link at the top of this Website lists loads for the 50 gr. Berger HPBT bullets for Hodgdon powders and for IMR powders.

I'm in the process of working up loads for the 55s also. I emailed Berger asking for some load data and here is what they sent me. I'm getting my most accurate rounds with a COAL of 2.480".
