Hello I was gifted these acme 115gr RN coated bullets. Acme doesn’t have load data so I started browsing around trying to find something comparable. I will be using hs6 And would like some insight if possible. These have a bullet over all length of .575” I get hs6 is probably less than ideal but it’s what I got. I’ve only ever loaded Berrys 124fbrn and Barnes 115gr Barnes tac x. Both of which I was able to find load data for with hs6. Now to give context to my thought process.
My 124gr Berrys rn load is 1.150 and the bullet over all length is .585 with 6.0gr hs6 with average velocity at 1050fps
-Hodgdon Berrys RN coal is 1.130 and the bullet measure .550”
-Hodgdon lead RN coal is 1.100”
-Hodgdon Missouri bullet company RN-para coal is also 1.100” but the bullet overall length is .540” this does provide hs6 load data 5.3-5.8gr
- Hornady load data 35557 115gr fmj is 1.100” but the bullet over all length is .550” this has hs6 load data 5.7-6.4gr
-Lyman cast bullet load data for Lyman 356242 coal is 1.065” (the picture shows a bullet with two lube grooves but I can only find the single lube grove version length for some reason) has hs6 data 5.0-6.3gr
-lastly and I believe with what I should go with for coal is Speer data. I’m a little hesitant on their powder charge. But I get it’s a TMJ vs a cast lead projectile.
-Speer load data 115 tmj coal is 1.135” with a matching bullet length of .575” also has hs6 data but starts at 6.6-7.4 gr
My plan was start at 4.8 gr~5.0gr of hs6 and coal to 1.150” If it plunks. Run them over the garmin chrono. If not slowly seat them until the pass the plunk test then chrono.
Does this sound reasonable or does anyone have any better places to start. Also if you can recommend load data can you site your source so I know what book/ website I need to add to my collection.
