Hi folks,
Has anybody else purchased/loaded/tested any of the .224" 55 Gr. FMJ-BT's that RMR currently has for sale? I ordered 2000 of them to use since the Hornady 55 Gr. are all bought up, and have a question...
First off... These were sitting in my mailbox 6 days after placing the order. I did NOT expect such a fast turn-around given the absolute deluge of orders that RMR is currently experiencing. Well done Jake and Co.!
Ok... I was planning to just load these using Hornady 55 Gr. load data, thinking they'd be pretty similar to the Hornady bullets. But while seating a few of these, I discovered they're quite a bit longer than the Hornady 55 Gr. SP I use. Specifically, the distance from tip to canelure is quite a bit longer. So to load these with the canelure centered at the case mouth I have to push the COAL up to 2.250" or so, while Hornady calls for 2.200" for their SP and FMJ bullets (and I actually load them a bit shorter to center the canelure). That's a larger COAL change than I was expecting, and I wanted to see if anybody knows what bullet this actually is? I'd like to check against data for this actual bullet if possible before proceeding. I sent the question off to RMR as well and will share their answer when I hear back, but thought I'd ask here as well.
Or do folks more experienced with rifle loading think that big a COAL change is OK? I know I'm pushing the bullet closer to the rifling and reducing freebore by increasing COAL. My understanding is that for rifle cartridges that will increase pressure more than the increase in case volume will decrease it. Just want to stay safe.
Thanks very much!
