I have a 750+ old Remington .224" bullets. They are in the the old red boxes with white and green writing on them. They are listed as 55gn HP Match Power Lokt #B22958. I was wondering if anyone may have some old data for them using IMR 4064 powder. Money is tight right now and I need some bullets so figured I'd shoot them up out of my Savage .22-250. I'd just work a load up for them but these have a concave base to them instead of a flat or boattail so I'm not sure how that would effect pressures and was hoping to at least find a starting point for them. I can post a pic of them if needed by anyone.

Thanks

You don`t need to worry about who made the bullets just what they wieght. Flat base or boattails not a problem either, some group better than others in some rifles. The only time you need to watch are with some of the specalty bullets such as Barnes VLD. As long as the seating depth is proper work up a load for your rifle with the powder you have, good to go. Never seen any with a concave base but shouldn`t matter.
 
That bullet use to be Remington's Match bullet. I used the 80 grain in a 6 mm Remington. Very accurate and devastating on groundhogs. I also used the 50 grain in a .222 Remington.
 
My cortrdige conversion book lists a 55gr Spire Point loaded over 35 gr of 4064, giving 3575 fps at the muzzle. It does not say if that is Max, Min or Best for the load though from what I have seen in loads I have used, they are usually at Max in this book, so I'd recommend starting at least a few grains lower and working up.

I don't have my recipe book handy to see what I was loading for my uncle, but I know i was a compressed load that he had worked up for his 22-250.

Regardless, any reload book showing 55gr bullets will give you a starting point to work from.
 
Thanks for the replies guys. I have all kinds of data showing starting loads for 55grn bullets. I just asked about these as they have a concave base and after doing a bit of reading the idea is for that base to expand and help seal the barrel better. I did some comparison of other bullets with botjh flat and concave base and the concave bullets seemed to run at higher pressures which makes sense. In some cases quite a bit.I loaded some last fall witrh what. I figured as a mild load and noticed some primer flattening but want sure as I saw the same with that batch of primers in my regular loads. Was just hoping someone had some bullet specific data I could use as a reference.

Thanks and Merry Christmas

With 4064, you should find a home in between 35 and 36 grains. My M-700 would shoot half inch groups with any 55 gr. bullet with about 35.5 grains. I believe it was the accuracy load in the sierra manual. (or within .2 gr. or so) . Let us know how that works out. Seating distance might make a difference in your gun, I had to be fairly close to the lands for best accuracy .
