We investigate the spectral norms of symmetric $N \times N$ matrices from two pseudo-random ensembles. The first is the pseudo-Wigner ensemble introduced in "Pseudo-Wigner Matrices" by Soloveychik, Xiang and Tarokh and the second is its sample covariance-type analog defined in this work. Both ensembles are defined through the concept of $r$-independence by controlling the amount of randomness in the underlying matrices, and can be constructed from dual BCH codes. We show that when the measure of randomness $r$ grows as $N^ρ$, where $ρ\in (0,1]$ and $\varepsilon > 0$, the norm of the matrices is almost surely within $o\left(\frac{\log^{1+\varepsilon} N}{N^{\min[ρ,2/3]}}\right)$ distance from $1$. Numerical simulations verifying the obtained results are provided.
