Speaking from competing in PRS last year with a Savage and this year with a custom, I'll drop my .02....
My savage was accurate, 1/2MOA out to 600 (furthest I have to print groups) with Eagle Eye 175gr factory ammo.
I started out shooting it because I had put it together a year or two before jumping into the PRS game. I bought a 10FP in 308 with a McMillan stock. It had their normal straight target crown barrel. I had the 10rd double stack box mags so it was a good enough starter.
Before going to my first I turned the trigger down as much as I could without it bump firing (1.5lbs), got a light bolt lift kit, and jumped in.
I wasnt really serious about it, just shooting it for fun seeing what it was all about.
Like 95% of new shooters I had a limited budged and I didnt want to get too far into it financially building a PRS specific rig not knowing
(At this point I'm $1500ish into the rifle itself.)
As I kept shooting my performance kept getting better and better, having more and more fun. And here is where Murphy that someone mentioned above popped in...
Bought a new trigger for it so that I could get under the 1lb weight. +$160
Bought some CDI bottom metal to fix the magazine/feed issues I was having with theirs and the aftermarket 10 round mags. ($220 and $160 for the AI mags)
Next match I went to (season finale), I was stoked to finally have a good ironed out setup rifle.... cleaned the first two stages of the day, get on the PRS barricade.....THERES MURPHY! The bolt came uncocked and I couldn't get the bolt closed. So after hitting my first two rounds, I had the issue. Spent a minute figuring out and fixing the malfunction and it really fucked my standings for the day. Still finished in the Top 20, but after all the money spent ($2000ish at this point) I still was having issues. I wasn't going to spend another $300-$600 re-barreling it and sink any more money into it.
Built a custom gun on a Big Horn action and havent looked back. I wish I would have left the savage alone, saved my money and just shot it how it was, and built a custom rifle while I was still improving with the savage.
I still recommend people jumping in with a budget gun, maybe something they already have. The accuracy on my savage was great, it was the reliability that really bit me the few times that it happened.
But don't go and buy a Savage, sink money into it hoping it works great eventually, and then get sucked in and end up spending $3000+ on a custom gun anyway. Save your money.
