223 barrel length?

Tikka 1:8 standard length barrel
80 amax 2800
80 targex 2880.

savage model 10 with 18 inch truflight 1 in 7 barrel.
75gr Amax 25.5gr 2208 2830 fps

65gr gamekings 23.5gr BM2 2880fps

but shoot to same POI at 100meters

chop it to like 14 inches

Not the heavier pills you are asking about but my 13.5inch barrel shoots 52g pills at 3000fps

I still have a large drum full of empty brass (watch this space) Prefer a bit more horsepower now.

Now where did I put my rangefinder....................................... .................................................. .....................

I never said I invented it [emoji12] and see you still have one, so you can't be completely silly!!! Hehe GO THE .223!!!

Didn't see my mention. I have found you just need to experiment. Different bullet and powder combos give wildly different results in different guns. Some numbers off the top of my head for different loads:

68gr Hornady BTHP, 26gr 2206H, ADI brass, Murom primer, 16" Colt barrel = 2864 fps

65gr SGK, ADI brass, compressed load of 2208, CCI 450, 16" Spikes = 2750ish fps. Max charge of 2206H gives mid 2650ish.

75gr Hornady BTHP, ADI, compressed load of 2206H, CCI 450, 16" Colt = 2750fps

I struggle to get most cheap 55gr bullets over 2900fps with adventurous loads and the above barrels. Have had 53gr V max in the 3100fps territory but it shot like poo. Remember with a "fudd" stick you probably can't load as hot as I do and get away with it. Both the above Hornady loads are very accurate and fast. I have killed a few goats with the 68gr and never witnessed a more effective killing .224 bullet. Have shot exactly one deer with a .223, and it was shot in the face at about 10yds with the 65gr SGK. Predictable results. Keen to shoot something with the 75gr, by all accounts it is a savage bullet. Most interested in the new 77gr TMK bullets, when they are actually a thing on the shelves. A heavy plastic tipped bullet that fits inside an AR mag and has a G1 over .4 will take things to another level.

wtf is a fudd stick??

A run of the mill bolt action

I have one of those and an AR and I think the BA would stand up better than the AR :) + I wopuld not like to rupture a case on the AR as no gas handling

Yip

Yeah I'm happier loading hot in a bolt action than an AR15 I think? What's your theory?

Thanks Beavis. That's a bit of stuff I was after.

I might have to go have a look at what differences there are between the 75 amax and bthp.
What is a 77gr TMK (tipped match king?)
The only thing I shot with robs 223 with 75gr amax was a rabbit at 150m. It was umm quite dramatic, head was 3m of hill and the ground was painted red

I shot a couple of goats at like zero meters with the 75gr BTHP at 2350 fps and was not impressed


e:75gr amax kicks ass tho

Righto thanks @gimp

My theory is that a 5.56 AR will run safely at higher pressure than a SAAMI spec rifle by default. I'm certain an AR will catastrophically fail due to a hot load before a bolt gun will, but if the AR is designed to run higher pressure loads off the bat... Proper mil spec guns are proofed with a 70k psi load. Ramshot manual lists 5.56 loads running in the 60k psi range versus 55k for a normal .223.

I'm also super keen to try the 155gr TMK in my shorty .308

But eg a remington 700 comes chambered in say 7mm rem mag as well as .223 with a 65k psi operating pressure and a larger case head so more force overall on the same size lugs etc

Pressure specs can be a bit meaningless?

Sort of, it really comes down to the rifle. I don't think you would have much worse than a sticky bolt, maybe a blown primer running warm 5.56 loads. What I meant was you may run into those issues with bolt gun if trying to hot rod it like I do. But those loads above are out of the book anyway.
