Why not the Nosler Partition?
I know this kind of thing has been covered before, but I had to get this out of my system as some sort of Mea Culpa to the folks at Nosler. I have used the Nosler Partition in the U.S. for everything from 90-100 pound Coues deer to a Shiras moose that would've tipped the scales in the 900-1000 pound range. The moose was taken with a 160gr NP out of my 7mm, the same was used for a number of elk. Not a single animal hit in the boiler room with these has ever made it very far except for one small elk that went a 100 yards or so leaving a blood trail that Ray Charles could have followed.
I don't know how many times I read or hear someone say that the NP is an okay bullet but lacks accuracy. I can't and won't argue with someone else's results, but it always makes me chuckle a bit because I can always find an accurate load recipe for the partition. And I've done so not just for my rifles but usually my loads work in others rifles in like caliber.
So during this year I've working on loads for my M70 in .300WM. I was bound and determined to find a load in either the TSX/TTSX, A-Frame and/or the North Fork. Eventually I settled in on a good 200gr A-Frame load that consistently gives groups right around 1", give or take a 1/4". But along the line as I cleaned my rifle I started sending NPs down the tube as just fouling rounds. On one particular trip to the range I notice the partitions were grouping well with whatever powder it was I was using. Again I wasn't trying to develop a load for these, but dang it if it wasn't finding me.
So I decided a couple of days ago to buy a box of 200gr Partitions and give them a go. This first picture is of a H4831 load at 71.0gr. Note this is a bit above max as listed in the Nosler manual but below max per the Hodgdon website. I also am seating these bullets to 3.38", 0.04" more than SAAMI.
Of the H4831 loads this was the most accurate. On to IMR7828 loads. The next pic is of the 73.0gr load. I was not using my chrony today as my tripod was devoted to using the new spotting scope that Santa brought me, so I don't know the velocity. But by the charts I'm guessing it's only plodding along in the 2700fps range, but with this kind of accuracy.....
The next pic is of the 73.5 and 74.0gr loads again in IMR7828. Noticing that the 73.5gr load POI was virtually the same, I went ahead and shot the 74.0gr load at the same target to see how they'd overlap. The three shots most to the left are the 73.5gr and those most to the right are the 74.0gr loads.
So if anyone from Nosler ever reads this, my hat is off to you. That old ancient Partition just continues to work for me.
I still plan to use my .375 with the 250gr North Fork for Eland but if the .300 is in hand and the right bull presents itself, I do believe the 200gr NP will be up to the task.
