Cool Suhl — Rimfire Benchrest Rig with Home-Built Stock

Suhl 150 IR 50/50 cedar stock

Forum member Evan K. (aka “Katokoch”) has crafted a nice rimfire benchrest rig using a Suhl action fitted into a handsome home-built cedar and carbon fiber stock. This shows what a skilled hobbyist wood-worker can create in his garage. Evan tells us: “Here is my Suhl 150-1 with a factory 1:19″ twist barrel, Leupold 36X scope, Harrell tuner, and my handmade cedar/carbon fiber stock. I started working on the laminate blank a couple years ago and finally finished it earlier this year. I’ve been using it in my IR 50/50 matches this summer. I haven’t shot a 250 with it yet but I know the rifle is very capable — as usual, I am the weak link!”

We think Evan did a great job on his stock, though he has limited stock-building experience. Evan explained: “The stock is my first attempt at making a very lightweight laminate and also gluing both vertical and horizontal seams in a blank. The wood is Spanish and Red Cedar and I made the trigger guard and buttplate with carbon fiber too (great use for small scrap pieces). The finish is hand-rubbed spar urethane and the action is semi-glued-in with Devcon 10110 and stainless pillars.”

Turnkey Rimfire PRS Trainer from Masterpiece Arms

MPA BA rifle .22 LR rimfire
Don’t worry — you can get this gun in eight different Cerakote colors: black, bronze, flat dark earth, gunmetal, marine red, NRA blue, green, and tungsten.

To succeed at the PRS game you need position shooting practice — and lots of it. Thankfully you can train affordably using a .22 LR rimfire rig. Decent rimfire ammo can be purchased for 7 to 10 cents per round, an order of magnitude cheaper than centerfire ammo. For the best results, you’ll want your rimfire trainer to sport the same ergonomics and “feel” as your centerfire match rifle. You can get just that Masterpiece Arms 22BA, a “turn-key” PRS rimfire cross-training rig. The MPA 22BA Bolt Action Rifle combines the proven CZ 455 action with a custom Spencer barrel and modern MPA modular chassis. With this chassis you can easily adjust length of pull, butt-pad height/cant, and cheek riser position. Chambered in .22 LR, the MPA 22BA Bolt Action Rifle can change to .22 WMR and 17 HMR through a simple barrel change. So, this gun can do double duty as a .22 LR trainer and a 17 HMR varmint slayer. Basic MSRP is $1599.00.

The MPA 22BA Bolt Action Rifle is available with numerous rugged Cerakote finishes: black, burnt bronze, flat dark earth, gunmetal, marine red, NRA blue, sniper green, and tungsten. Custom Cerakote colors cost $135 extra for the chassis body and/or $65 for the barreled action.

MPA 22BA Bolt Action Rifle Specifications:
Caliber: .22 LR (.22 WMR and 17 HMR via barrel change)
Action: CZ 455
Chassis: MPA CZ455 BA Chassis, 13.50″ – 14.75″ LOP
Barrel: 416RQ Stainless Steel Spencer / MPA barrel, 1:16″ twist
Barrel Length/Countour: 16-24” (customer specified), 0.920″ straight
Barrel Muzzle Thread: ½-28 TPI (if requested)
Trigger: CZ 455 Trigger (yoDave Trigger Upgrade, 1-3 lbs.)
Magazine: CZ 455 10 round polymer magazine with DIP floorplate
MSRP: $1,599.00

The CNC-machined MPA chassis has some very cool features: enhanced vertical grip, thumb notch, built-in bubble level, MPA trigger shoe, and spigot mount with lower-mounted Picatinny rail. The rig comes with a D.I.P. +25 MOA Picatinny scope base and you can add side Picatinny rails, as well as increase the distance from the spigot-mounted bipod to the rear support. The chassis is also compatible with a barricade stop system, an extra-cost option.

Masterpiece Arms centerfire chassis systems have won 5 out of 12 recent PRS matches (story HERE).

Why rimfire cross-training? Because this stuff is ten cents per round. Premium handloads can run $1.00/round (counting brass depreciation), and the best factory ammo can cost over $2.00/round.

A Rifle is Only As Good As Its Barrel
The key to accuracy for any rimfire rifle is a great barrel. The MPA 22BA Bolt Action Rifle includes a precision drilled, reamed, and honed Spencer / MPA rifle barrel made from 416RQ stainless steel. The hand-lapped barrel is inspected with a video borescope. The chamber is indicated within 0.0001” or less to the bore of the rifle.

Or do you just like the extra performance you can get from a specialty cartridge such as a 20 Vartarg or 22-250 AI? Well, if you love wildcat cartridges, you’ll probably enjoy this book. Now available for the first time since 2003, The Handloader’s Manual of Cartridge Conversions explains the processes and tools needed to convert standardized brass into hundreds of different rifle and pistol cartridge types. A vast variety of case designs are covered — from vintage cartridge types to modern, cutting-edge wildcats.

This classic reference guide has been revised with an easy-to-search format, complete with a full index of hundreds of cartridges. This book belongs on the shelf of any hand-loader who enjoys making and shooting wildcat cartridges. However do note that much of the text is unchanged from earlier editions. For some cartridge types, the author recommends “parent” brass brands that are no longer available. In other situations, there may be more convenient conversions now offered. Nonetheless this is an important resource. As one verified purchaser explains: “Great reference for making the cartridges that are hard to get or no longer in production. Offers an alternative to the the time, expense and effort of having to re-chamber a classic. Saves ‘Grandpa’s shooters’ from becoming safe queens.”
