No I'm saying if I can do it with a Varmit rifle, there's no worries about the actual sniper rifle's effectiveness.
It's an imbalance when the sniper rifle is balanced against probably the weakest humans in the game, while all other weapons are balanced with each other.
Post-patch, the sniper rifle does comparable damage to the Cowboy Repeater (using JFP ammo and Cowboy perk), with the Cowboy Repeater actually doing more damage against armored targets.
Post-patch, the Trail Carbine does up to 50% more damage than the sniper rifle.
Both the trail carbine and the cowboy repeater beat the sniper rifle in every other stat (attacks/sec, dam/AP, weight, item HP). Except spread, which is unnoticeable - e.g. the Hunting Rifle has the same spread as the Trail Carbine, but people use both to substitute for the sniper rifle, all the time.
