RL 17/80.5 gr Berger Full Bore
« on: October 11, 2020, 07:19:04 PM »
Worked up several loads with the remaining bullets i had left.  I started with Sierra's data for the 80 gr SMKs starting at 26.5 intending to work up to 28.5(Sierra 's max is 28.6) but i had a near full case at 27.8 even with a 4" drop so this will be my max load.  Loads started getting crunchy at about 27.4.  COL 2.28+/-

I also worked up a few with 77 gr TMK's ranging from at 27.6, 27.7, and 27.8.  Will post results once weather clears.
Hornady brass trimmed to 1.585, BR-4s, with a COL of 2.25+/-

Ran my loads for the RL 17 today and was a bit surprised and disappointed I didn't have a chrono for velocities.  I ran 6 charges ithin the range previously mentioned.i think the first group was spread due to the cold bore but the second at 27gr closed up nicely, the rest fanned back out.  I noticed ejector marks almost through the entire range starting at 27 and were very heavy at 27.8 gr. but primers looked good throughout.  Id like to retest once i get more 80gr bullets in this week, i think 26.8-27.2 could show some promise.  I will say this powder is dirty as hell but i was pleased with the .71 group at 27gr.

The 77s did ok as well, I only had 9 bullets left over do 3 hot groups with 3 charges.  27.6gr faired the best at .89.  Ejector marks on all 3 charges.

Something I will mention that may or may not be of interest,  I zeroed my my to the cfe 223 that I had previously tested.  POI remained the same with AR COMP more or less, but was 2" right and 2" high with the RL 17.

Assume your shooting at 100. Nice. Ive got 1600+ rounds on my barrel now and shot some groups at 100 yesterday for the first time in awhile to calm my nerves for load development on a new rifle. Was pleasantly surprised with several groups a dime would totally cover. Mine has been ridiculously accurate after a really tough search for an accurate load. Ended up with 25gr of Re-15 behind 88 ELDs at 2.3 ( max mag length). 24 heavy Krieger. Glad to see someone else finding accuracy. Ive shot hundreds of rounds out to 1000 yards and these tiny little bullets cheat the wind better than I could have imagined . Many .5 moa groups at 1000

That's outstanding.   RL 15 is non existent right now but I have several others try, imr 4064 is next up.  I should have bullets in later this week along with my chronograph.   correct though it was set at 100, just dialing it in for fun, varmints, and deer heads.  I tried 88s with cfe223, varget and got decent results nothing outstanding.  I'm shooting off of a heavy barreled BCA and a lower i built so I'm pretty tickled with a 3/4" group considering i got more money in my scope and trigger as I do in the rest of the upper,etc.  It seems to really like 80gr bullets but faired ok with 90s.  I tried lighter grain loads I had for 223 but several vaporized and didn't make it to target so I didn't waste anymore time. I have some 80gr noslers coming so I will post data with the 4064, but so far the 80gr smks are king in my rig
