Reloading help! 125 and 150 grains

[bangbangping]

In testing my bolt action rifles (2 Ruger American Ranch Rifles), the CCI400 was more accurate than the BR4's (100yd groups were 1/2" - 3/4" smaller).

Interesting. Is this with a specific load or across the board? Do you have a post of how you tested?

One test I ran focused on ES, not accuracy. viewtopic.php?f=141&t=97658

Bangbang, what manuals would you recommend. I have a handful of older manuals but none have blackout data. My go to has been speers number 12

id recommend hornady's 10th.

its the largest 300blk compilation in a published manual that i'm aware of to date, with 9th edition being the 2nd.

Hornady's only has their bullets in it, which is the drawback of any bullet MFG produced manual.

Lyman's 50th would be my choice. I only have the 49th (no 30blk) but it's my go to.

Specific load: LC formed brass, Barnes 110gr black tip, 20.0gr H110, mild crimp, no case anneal, 2.25" oal. Ruger American Ranch Rifle, 2-7x scope set at 7x. Target at 100yd. Sandbag rest front and rear. Crux Ark30 suppressor.

Normally I use CCI 400 in the RARR's (hard Wolf/Tula primers give some failures to fire), but I was given some BR4's from a ex-reloader he had left over. Thinking the BR4 HAS to be better, I fired some 5 shot groups with each primer, alternating between CCI 400 and BR4. Not only did the BR4 groups shift lower and to the left, they were also bigger. Now I was only given around 600 of the BR4 primers, so I simply used the rest of them up in pulled bullet plinking loads instead of working towards an accurate load with them by varying the powder charge since my RARR is a 1" rifle with the above load and CCI 400 primers. I did not chronograph the loads in that session. No failures to fire the BR4 in the RARR. Other testing/rifles could give different results.

I have 2 RARR's in Blackout with the discontinued short stock and rotary mags. They both shoot identical or close enough that I can't tell a difference. They both like the same loads and give similar velocities with the same ammo. It's like they are twins.

The Hornady #10 has a good breadth of 300 black loads. The Lyman 50th has some with the common powders.
Lyman 50th lists Hornady 150gr FMJ-BT 2.075" H110 start 14.5-16.2 max (2060fps on max load) This is 16" barrel length you will get less in 8".

I found the CCI 450's to work especially well when running compressed charges. Low SD and nice groups with several bullets of 150 gr variety. The BR-4's have never been the best in my SRP applications, including BLK and the .22 cal cases from .222 to .22-250. Dunno why, just had better accuracy with 205M and WSR. It seems some rifles/calibers will prefer a specific primer and not the one you think should be best...who knew

I Use Rem 7 1/2... there are videos out there that show the difference visually of the different primers... Remington are always consistent.

[Dolomite_Supafly]

I would try Lil'Gun as well. It gives some of the highest velocities and it has always been consistent for me. Only drawback is it may not work with cast bullets.

On another note. I cant find a agreed upon load recipe for hornady 150 fmj bt and h110

I’ve been loading them with 15.2gr @ 2.07” using LC brass and CCI standard SRPs
This is in an AR15 w/10.5” barrel. The load for your rifle might vary.
