Hey everyone, I'm seeking load data for my 6mm Creedmoor. I'll be shooting the Berger 109 Long Range Hybrid Target. I have RL 16 and H4350...can I get opinions on which of those you prefer and how much you're using? I'm mainly looking for a starting point for load development as I can't find data on this anywhere. Thank you in advance!
Seeking load data for 6mm Creedmoor with new Berger 109 LRHT
- Thread starter Maverick124
- Start date
I found a node with 40.2 gr of RL 16 .020 off the lands. I got 2959 fps with a 26" barrel. Lapua brass (new) and CCI BR4 primers. SD was 2.7 but I haven't done further testing on it. Group was around 3/4"
I'm trying to order now... I can't decide since my first 6mm. Between 105 hybrids, 109 or DTAC 115. I'll be shooting in high wind and 500-1200 yards. Last year wind was 18-22mph and we were launching 168gn 308 with 4 mil holds lol. Trying to stay in the game this year.
Bartlien 7.5, 26" .183 freebore. It's got 70 rounds of Hornady ELD box and shooting great.
I think any of those would shoot. I did a ladder test up to 40.8 and found another node right there with a higher SD but it wasn't bad. Debating about whether to opt for faster speed...
I would avoid the 105s at this point though...take advantage of the higher BC options
26" PVA 8 twist 5R, 39.2 RL16, .030 off lands, BR2 primer, Peterson brass .002 neck tension,3028. 28" X-Caliber 8 twist 3R, 39.6 RL16, .030 off lands BR2 primer, Peterson brass .002 neck tension, 3038. Both very low SD/ES #s on labradar and sub half inch groups.
Just shot 38.4-40.2 RL16, 210m primers and Hornady brass. There was a node for 109 Berger's at 2940fps (39.6-39.8). Now I ran that in my ballistics software and get 70 inches (1.9mil) drift in 10mph full value wind. Now if I up the powder and spin this up 100fps to 3040 the difference in same wind is 66 inches (1.8mil). Obviously real world might change the outcome but I don't think speed on these 109 Berger's are going to change much under 1000 which is what I shoot. So I'm not gunna chase that 3100fps goal and save some barrel life.
