Colonel. Major C.W. Williams-Wynn was promoted to succeed him, and in turn was replaced in June 1878 by Sir Watkin's nephew, Sir William Granville Williams, 4th Baronet of Bodelwyddan, The Montgomeryshire Yeomanry had been re-equipped with the Westley Richards .499 calibre breechloading carbine in 1871, and was rearmed again by 1881 with the Snider .577 carbine. Captain Aubone G. Fife, formerly of the 6th Dragoon Guards, appointed adjutant in 1882, laid great emphasis on musketry training, but this was hampered by the lack of suitable ranges for these more powerful and longer-range weapons. A partial solution was provided by Capt R. Pryce Jones, who refurbished the old volunteer ranges at Penarth at his own expense. The Snider was replaced by the Martini–Henry .455 calibre carbine in 1886, and in 1889 a new range was built at Llangedwynn for the Llangedwynn and Llanfyllin troops. Regimental headquarters (RHQ) was fixed at Welshpool, and Newtown was not used for training after 1885 because there was insufficient space there for squadron training. In March 1885 Aubone Fife was promoted to command the regiment, and was succeeded in turn on 2 February 1889 by Sir Herbert Williams-Wynn, 7th Baronet of Wynnstay. Because of difficulties in finding sufficient officers, the Caersws Troop was disbanded in 1889, and the personnel were transferred to the Newtown Troop. However a new F Trp was raised at Guilsfield in 1892. A reorganisation of the Yeomanry in 1893 saw the troops formally reorganised into squadrons. For the Montgomery Yeomanry this gave the following organisation: RHQ (Welshpool) – Lt-Col Sir Herbert Williams-Wynn A Squadron (Llangedwyn & Llanfyllin) – Capt Robert Williams-Wynn B Squadron (Welshpool & Guilsfield) – Capt A. Williams-Wynn C Squadron (Newtown & Berriew) – Capt N. Robinson As part of the reorganisation, from April 1893 the Army List showed the Yeomanry regiments grouped into brigades for collective training. They were commanded by the senior regimental commanding officer but they did have a Regular Army Brigade major. The Montgomeryshire Yeomanry together with the Denbighshire Hussars formed the 15th Yeomanry Brigade, part of 8th Division. The brigade first came together for training in 1895 at Welshpool under the command of Sir Herbert Williams-Wynn. Brigade camps were held at Rhyl in 1897 and at the Williams-Wynn estate of Wynnstay in 1900. In 1896 the Montgomeryshires were among the first yeomanry regiments to be re-equipped with the Martini–Metford .303 calibre carbine; reduced charge ammunition
