300 Black Out Accuracy
I am using a 16" Noveske 300 BO top end. Want to use 110gr to 125Gr bullets at super sonic speeds with good accuracy. By good accuracy I mean reliably 1" or better at 100yds after load development. Any of you experts out there have actual experience with this idea and willing to share opinion?? I am presently using Barnes,Hornady and SMK bullets and H110 powder,but have others available to try.Is a 1:11 twist worth pursuing?? Tnx.
Re: 300 Black Out Accuracy
Moa is very attainable with load development. Many on this board have achieved it and have listed their loads. Get a 1:7 or 1:8 twist for the best range of bullet weights that you can use.
Re: 300 Black Out Accuracy
If I can do it, you can do it. All the components you mention are quality, and capable of sub MOA accuracy. You could use a 1:11, but your Noveske is probably more than adequate for the job. I noticed while using the VMAX that max velocity is not max accuracy.
I needed a decent optic and trigger to make it happen for myself. I have a 1:7 twist.
If you have more specific questions, I'd be glad to share my experiences.

Guns are tools designed for dirty work both competitive and defensive. If I meet someone with a well worn gun, I hope their barrel is pointed the same direction as mine if the lead starts flying...
Re: 300 Black Out Accuracy
With jacketed bullets the 1:7 is probably good. A good trigger makes a lot of difference but a decent standard trigger should be fine for hunting where 2 MOA is acceptable. I'm playing with alloy in cast, got 1" x 1/2" 4 shot group @ 50, ~1800 fps, 150 gr. PB yesterday. 1:7 carbine with 7# trigger. I wasn't shooting for groups, just to see if the alloy did OK. Fine for 50-100 yrd hunting. I'd say just work up your loads with the bullets you have, don't change the rifle till you find you NEED something better.
Re: 300 Black Out Accuracy
The two most accurate loads I have come across in my Noveske 10" 300 BLK are the subsonic 220 SMK and the supersonic 125 grain SMK.
Both are 1 MOA accurate out to 300 yards and are closer to 1/2 MOA at 100 yards.
Subsonic 220 SMK
Rem / AAC Brass
205M Primer
10.2 grains A1680
Supersonic 125 SMK
Rem / AAC Brass
205M Primer
17.0 grains of N110

Re: 300 Black Out Accuracy
Will be using Barnes 110g TAC-TX FB,Hornady 110gr V-MAX and SMK 125gr-HPBT. Using H-110 powder ranging from 19.0grs to 20.0(.1 gr increments)-110gr bullets. With SMK,125gr-same powder ,slightly less. COAL-2.00" to 2.230",run out less than .002. Presume I am in the correct neighbor hood??? Tnx

Re: 300 Black Out Accuracy
i dont think you'll find very many bullets out there where max velocity = max accuracy. that said you should be able to find something close to the top end where there's a node and get you respectable accuracy with good load developementScottB70 wrote: I noticed while using the VMAX that max velocity is not max accuracy.

Re: 300 Black Out Accuracy
If you want the smallest group I would work with the 125 SMK. I started at about 17 grains H110 and went up from threre. Best groups were at the high side of the charge weight. 18.2 grains.
