7mm-08 quickload request 168 Accubond Long Range

[justramit]

I was wondering if someone could run quickload for me with 168 accubond long range in 7mm-08. Winchester Brass 2.880 Coal. 20" barrel. I was thinking Ramshot Hunter, H4350, or reloader 16.

thanks

Pretty sure RL16 will get you the highest velocity out of those powders...

Reloader 17 would be the fastest.

Reloader 16 would be fine.

Want it to be temp stable. Can get hot down here in texas, but want to be able to shoot in cold weather too. That was why I didn't look at 17. I have H4350, Hunter, Reloader 17. Will have to try and find some 16. I think Hunter may produce good velocity too though. Actually just noticed ramshot shows about 60 fps faster with Big Game. Might try that too. I think it is faster burning for short barrel

Not quite what your looling for, but should give you an idea. I asked for this a while back and saved it....

I think your pick of the 168 LRAB is a good one for that 20" barrel. "usually" one will get the best results ( accuracy, good speed, less muzzle blast) in a short barrel with "heavy bullets & slow powders". Now, in that cartridge, I suppose the "4350" range of burn rates is pretty slow. QL data helps with it all 'except" perceivable muzzle blast. If its an ear splitter, look at slower powders for that weight. BTW, I am planning on working up a load in my 7x57 with that same bullet. It shot wonderful in 2 .280s and a 7mm Rem Mag. It is one beautiful bullet!

if you want speed why not try the 150 ablr I get 2850 fps out of a 26 inch with h4350 and using litz tested .575 g1 bc it is pretty good to 600 yards

Thought about that too

See attached file. These are max load predictions; start low and work up. Sometime QL is wrong, and we don't know your actual case capacity and lot of powder burn rate.

As a fellow 7mm08 hunter, RL-17 has worked well for me (1/2 MOA) with 140 sierra PH, 150 hornady eldX, 154 SST, and 160 partitions. Win 760 is my second go to powder.

If the 168 ABLR don't work out, I would suggest you try the 150 eldx.

RL16 is so bulky, you run out of case capacity (108% in my experience is max) before you achieve max pressure.

Thank you!!!

glad to help.

I noticed you mentioned H4350 in your original post - updated file attached with that data (its 100 fps slower than RL17).

After splitting the seating stem in my forster die trying to compress powder in a 7mm08 case, I gave up on bulky powders like H4350 and stuck with RL17 and W760.

RL17 dose vary some with temp, but its not too bad. If you are overly concerned, usually a 0.2 grains adjustment is needed for summer and winter loads.

Honestly, I think most worry too much about temp sensitivity. As long as a point of impact shift does not occur, a modest loss in velocity (50fps) is negligible at distances out to 500 yards (2" impact difference ). Once you get to 600 yards, it definitely starts to matter for deer sized game.

I'm surprised you had so much trouble getting enough RL16 in a case. I have some 140gr E-tips loaded up between 48gr up to 50gr to test, just waiting for a good weekend. They are probably as long as a 160gr Accubond or other similar bullet.
