5 of 5 CVA Accura v2/ Remington Ultimate 700 Muzzleloader July 23, 2019
Reviewer: Corbin Henrie from Pleasant Grove, UT United States  
Was only getting 1 inch groups with 90gr BH209 and no more if I loaded more than 90 gr Powder or over 100 gr pellets groups opened up to about 6 inches. Bought these and loaded 120gr BH209 and first 3 shots were touching at 100 yards. Also shot 1 1/2 group at 200 yards,  and 3 inch group at 300 yards. I am using 327gr parker productions black max 120gr BH209 Federal 209A shotgun primer with CVA blackhorn breech plug. I am very impressed with these. They also helped in my father inlaws remington ultimate 700 muzzy. Couldnt get any bullets (SST TMZ TEZ Great plains, maxi hunter, TC shockwaves, harvester scorpion) to group besides remington accutip (barnes with specialized sabot that is unavailable other than with Remington accutip bullets) using max load (200gr/4 pellets 777). He tried these and went from 5 inch group at 300 to 3 inch and 300 yards these things are legit and work great they are a must for magnum loads!!
