With light varmint bullets the dasher will give you plenty of speed. Question is how long are you going to run your barrel, and are you considering suppressed?
In regards to brass, just buy Alpha and be done. I'd recommend running detachable mags for excellent feeding--either the MDT 6BR mags...
I wouldn't fret over 100 fps difference with these long bullets. Just dropped my 175EH profile 100 fps in my solver and it added 0.1 mils of wind (full value, 10 mph) at 1000....and the wind is what you need to be most concerned about.
I have 198 Ct Nosler accubond bullets, 200gr/30 cal for sale.
Half of them have been HBn coated. Used to shoot a lot of HBn and decided not worth the effort but also no ill effect and I’d switch back and forth.
Anyway, don’t need these. Asking $225 shipped. PayPal FF, Zelle, Venmo or...
How well do Bat's handle dirt and weather? Obviously speaking to past tactical/hunting models, not ther BR/F-class stuff...Hammerhead action is interesting, but it has to handle the elements.
