In the picture are 3 versions of the same mould number. These 225438's all have different weights & diameter using the same alloy. I'm gearing up for a 22 hornet project using these and 4 other .22 cal moulds. In Cast Pics under Members articles, is piece I did last year for Beagle on the 218 Bee. In it I tested using 3 different .22 cal sizing dies. The results went against what you read about what size do you make your boolis. The standard quote is "SLUG YOUR BARREL", but the people that tell you that don't expound as to why. More than likely they haven't a clue themselves. What your looking for is a sweet spot's plural!! Not only barrel length, but amount and type of powder you use, boolit size and alloy, seating depth, etc.
The rifle I'm using this time is a very old 1930's vintage Krag with a Springfield 22 barrel dated 1937 with a 10 power Lyman Perma Center scope attached. Brophy says Springfield barrels were made with groove's, depending on year, from .2225 to .2235. Knowing that doesn't help much either. How fast or how big the boolit needs to be to shoot best can only be found by testing. In the 218 Bee piece I used a .222, .223, & .224 sizing dies. I have a .225 also, but I know from past experience it's not going to worth my time to test it.
At this point with a foot of snow on my range, I'm thinking it'll be a month or more before I get these three 225438's tested along with 4 other boolits. As you can imagine assembling them takes time. Off the top of my head, I'd say the .222 sized boolits will outshout the others, but only will tell. Last Summer I did some preliminary work with that Krag and it'll shoot half inch groups with the "other kind of boolits". The old Winchester military survival stuff chronograph ed 2900fps and grouped 1.5" Sweet spot velocity range last year was around 2100fps with cast. I did get a few 1.25" groups with several boolit styles.
My intent here is to scare the bajeebers out of the newbies. Naw, not really, as you get older and accumulate more reloading "JUNK", you can play games testing....Geo
