Anyone have/use a recipe for a reload for an RMR 62gr FMJBT W/C on a std 1.75" case, CCI 400 primer?
I'm going to load up about 100 on top of 25gr of H335 with an OAL of 2.25" light crimp mid cannelure based on what info is on the powder container for a 55gr round. This load seems to work well and is accurate with 55gr bullets at 2.22" OAL light crimp at mid cannelure. Interested to see how the 62 grain will react with same load. Just checking to see if anyone has used these bullets and what type of powder seems to work well. I may try some ARComp and Reloader 10x I have, but not sure on how much powder to use. I shoot different ARs, 16" and 20", but all are 1:9 twist, one being a Wylde. Any info is greatly appreciated. |

I'm not familiar with RMR 62 grain fmj bullets but think you should lower the powder charge at least one full grain below what you use with 55's and proceed from there. ARComp should be useful in this application, RE-10X is a little too fast but will work in a pinch.
Hodgdon has data online for free. Don't start at the top unless you like things that go boom right in front of your face. |

Quoted: Do not waste a 100 rounds on pulling a load out of the thin air. Do a proper load work up and look for the best of all three world Safety Reliability Accuracy Do not copy loads! Reload properly and save yourself grief and frustration Don't begin at 25.0 grs. That's what I worked up to in my rifle for SS-109's (62 gr FMJBT). Your rifle is different than mine, and I used different cases and primers in my loads. Be safe, work up your load. You can get by with 3 to 5 rounds at the lower steps, but this is important to do.

The RMR 62 gr are pulled "Fusion" bullets.
If you have a chrony dial them in at 2800 fps. That's where the original Federal Fusions are. (shot from a 20" AR 1/9 twist) Since they are generally considered "plated", don't push them too hard. disregard, I didn't see the FMJBT part... |
