Good lord yes those should be easily attainable without gear and MANY have surpassed that witout ever touching gear.
It all boils down to you how you are built. lenght of arms legs torso etc. Me for instance. I have LONG arms and a shorter torso. It make DL's my strong point Currently just below 250% of my BW by a few lbs. and benching HARD currently just below 150% of my BW. Squat is 200%+ of my BW and I have never touched gear.
How about you not ask what is doable in a year and just set those as your goal and do your DAMNEDEST to not only reach that point but surpass it.
Good luck, Work hard, eat BIG/right for your goals.
