Reloading 303, any experience with Prvi or Campro bullets?

[cosmic]

Just curious, did you bother "tuning" any loads with the Campro bullets? I wouldn't expect much out of a RN bullet myself but 2.5"/100 isn't great.

Yes and no, I generally load to mid-range load levels using RE15. For me, RE15 has consistently outshone other powders, so I stick with it. I havent investigated that new fangled Varget powder, its on the to do list. For a typical rifle, I will load Hornady 150's, Hornady 174 RN, and any other bullet I wish to compare (Sierra, Campro, etc). COAL is set to 30 thou off the lands. Based upon the results at 100 y, I will declare a preferred bullet. I will then further test that bullet by adjusting the load, say plus or minus one grain in range.
I have tested several 303's in this manner, of all action types. The odd rifle will favour the Campro, but I think its fair to say that rifle has limitations on accuracy (bedding, etc) that are governing the bullet performance - eg erratic groups, stringing, etc. In rifles that are known to be accurate, the Campro loses to the Hornady and Sierra offerings consistently. I have shot the odd 1.5 inch group with the Campro (4-5 shots at 100 y), but the norm is closer to 2.5 inches. The other mentioned bullets can go moa or less if I do my part.(ie the rifle and bullet combination is now testing me.)

Great info, thanks!

I've been shooting the Cam-pros for a few years now. In some of my rifles, they shoot better than the Speer &/or Hornadys. Some not. They all, however, shot better with the 180 gr. Sierra bullets. They all feed like greased snot in my commercial Lee Speed or Parker-Hale rifles, if you seat them to the cannelure. 42.0 grains (try 41.5 - 42.5 gr., but 12 of 15 rifles shot better with the 42.0 gr. load) RL15 & WLR primers (in most of my rifles WLR work better than Fed or CCI, although the difference between CCI & WLR is not as much compared to the Federal primers, which I now only use for cast bullet loads). RL15 is, however, temperature sensitive.

PPU brass is your friend, as it is made to military specifications & shouldn't cause incipient separations. Or see if you can find DI 43-45 brass, as that stuff is also quite good. Then again, I expand the necks before first firing, then re-size using a Redding bushing neck sizer & a .375 Fl. N.E. 2 1/2" body die.
