270 wsm Accubond and Magpro Loads

[jbadje]

I have been searching for Magpro and 140 Accubond load data. I don't see anything on their site for this particular bullet.

I'm looking to see what most are working up to on their test loads.

I have shot 74 grains but it craters the primer and groups were not good.

I have WLR primers and nickle plated Winchester brass.

I was going to do start with 72.5 and load my way up but wanted to get some more input.

thanks in advance!

This is the best combination for big game that I found in my factory 1885 Winchester with at 28 inch barrel. The Western Powders website has a pdf file of their load data. I see that 74.2 gr is listed as the maximum. I found this a little hot for my Norma brass in my single shot which does not have the camming force of a bolt action. This is my data with MagPro and 140 ABs:

140gr B-tip Magpro 73.5 gr 3302
11/7/2011 CCI 250

140gr B-tip Magpro 74 gr 3332
11/7/2011 CCI 250

140 gr AB Magpro 74 gr 3299 22.34502 12/4/2011
3272 3295 3290 3303 3333
1/2 inch group
140gr B-tip Magpro 74.2 gr 3340

140 gr AB Magpro 74.0 gr 3222 19.49872 5/7/2012 Wolf sort 3222 3201 3196 3206 3244 3226 3239 3242 3225
