I used Bulletcorp when they first started. I then tried the other polymer bullets and now going back to Bulletcorp as there are no issues with Bulletcorp.
I find great quality and consistency in these bullets. My ES is very low using them. The weight is very consistent and the coating looks great. Finnish of the surface is nice and smooth and the coating does not come off. I am happy with these bullets and can recommend them to anyone who is looking for these types of bullets.
After trying out a number of bullets in my finicky Shadow 2, I finally standardized on BulletCorp coated bullets. Measurements of bullet length and weight showed low levels of deviation, which resulted in very consistent reloads (STD < 7 ft/s). The 135gr is a nice compromise between cycle speed and recoil management, and I use them exclusively for IPSC activities.
I have been using the 115gr bullets from Bullet Corp a while now for Pistol Calibre Carbine competitions and can't be more satisfied with them. I have nearly finished my first 1000 135gr match pro bullets from Bullet Corp and I must say, their quality is exceptional and they work like a charm in all 3 Glock pistols I use for competition. I can highly recommend them to any sport shooter. Bullet Corp's quality and consistency is in my opinion the best out of all powder coated bullets currently available in South Africa.
