I put a Williams Peep with front Firesight on the 336CS 30/30 that I picked up recently. With the rear peep lowered to its lowest point without touching the receiver, bullets strike 8" high at 100yds. Factory loads and handloads. My question is whether to replace the front sight, and if so what height should I go for. MidwayUSA has many to choose from. If I remember correctly, I measured the factory front sight at .340". This weekend, I'll pull the Firesight front and measure it. Any info will be appreciated. Thanks.
