Have a 336 in 35 Rem. It will shoot first shot close at 100 yds, but then they start to climb. All of the shooting is done off of sandbags and a table. I can let it set for 45 minutes to an hour and it will shoot back on target. I have read the tips on accurizing, relieve the forearm, loosen the barrel band etc. and have done all of this. Still it comes out of the safe and shoots first shot right on and then starts climbing, as much as 8 inches. There is even a difference if I leave it out on the sandbag rest or if I put it inside for the waiting period. If it is out in moderate heat it will continue to shoot high, bring it in to the A/C it will shoot closer. Any thoughts or suggestions. I had been shooting Hornady factory loads,but got enough empties to start reloading, Leverolution and Hornadys FTX 200 gr.
