I just picked up the RCBS Rock Chucker Supreme Master Reloading Kit this weekend. Now I just need to build a bench and buy components. I need to work up a load for my new Encore 22-250 for prarie dogs. Plan on starting with 52 grain Speer HP's. What powder would you guys recomend I start with? I have read the Speer manual and all of the manuals that came with the kit, any other peices of info you guys think I should know before I get started?
Thanks for any info,
SWAT
I would recommend that you start with H4895, if you do you may have no need of WW 748, IMR3031 or H380. 36.5 is listed as maximum in my Speer manual with 35.5 as listed maximum in my Hodgdon manual. I would say start with 32.0 grains and work your way up until you get really small groups - that is going to happen between 33 and 34.5 grains (my educated guess). Don't wory about velocity you will have more than enough to do what you want to do with your gun. Just get a load that shoots under 3/4" at 100 yards (you will probably find a load that shoots to 1/4" or slightly larger).
If you need a small, portable bench let me know I have plans that are in dimensioned drawings that you can build in about 1 1/2 hours and take with you where-ever you go. I have three of them - one for pistols, one for rifles and one for shotgun reloading. I got tired of leaving benches behind when I moved. My brother needed one for his apartment and I wanted one that traveled easily. It takes up about 2 1/2 x 4 feet of floor space. It is great for loading just a few different kinds of rounds or if you have to have something that fits in an apartment or one that you can take with you when you move. These benches are rock solid with no flex even when forming cases and have an optional cabinet for bullets, powder and primers. There is room for trimmer, press, scale, powder measure and extra dies and miscellaneous tools.
Send a request to paulstephens2@comcast.net with "reload bench" in the subject line. I will email the drawings back to you immediately. You can feel free to send donations if you feel so inclined - They will go to my church.
