An important point in tuning my rifles, happened with Lapua ammo. I dished the tubes, because couldn’t no longer get a consistency up to my standards. I tried everything I knew and it didn’t shoot right. When this happens, I always went to basics. And basics in rimfire means a “clean rifle”. I do mean putting on the rifle only the basics, nothing else. I’m not going through a potential explanation, because I don’t have the needed backgrounds, but the cleaned rifle tuned immediately. Hummm…. It was the very same rifle I used on 2018, so what? Different ammo, for sure, RWS vs Lapua, and perhaps the fundamental point faster vs slower. In fact, since using Lapua all my selected ammo speed was (is) around 224~226m/s against 329-332m/s in RWS. Those velocities are manufactures box printed. I never took the time (wasted) to measure any of my rimfires. To those that still pounders to weight theirs .22lr ammo, please don’t waste your precious time, because you are putting on the same bag 5 variables. On top of that you can’t control any of them.
Until today, when someone ask me if should use a tube, a middle barrel weight, a rubber vibration absorber, I give the same answer. The more you put in the barrel the more complex it becomes to control. Keep it simple… you have enough to deal with just a tuner in front.
Find a Team, join a group of shooters with the same goal. Talk, discuss, analyze ideas, let the others shot your rifle, do the same with theirs, realize that all of you will grow faster together than alone. But always have a plan, and don’t go foul about mechanics, don’t try to explain everything, but do try to understand and how you could apply it. And, of course, have fun! A warning here, careful about burning out conditions. There’s more life than shooting.
Ah… don’t experiment on competition, there’s a practice time for it. Don’t change things before the great day, because your competitors will appreciate your move, you are going to fail.
When the gold moment arrives, the moment you pull the trigger (even if it should be done subconsciously… well, almost), you can’t have anything else floating in your brain than aiming. All else has to be automatic, already mastered. Any other thinking will change your POI. Controversial it might be, but I dare you to trust this: “if you don’t believe you’ll score, you’ll miss” … and learned since my very beginning: “aim small, miss small” …
Maybe you are wondering why I not yet talking about that Evil, eluded before in my writing? Well because now we reached two Evils…
SARS-CoV-2, the 2nd Evil
Yes, COVID-19 stroked my Country in March 2020. That was a total waste, shooting related, all closed, no matches (national or international), no more meetings, everything stopped… being a Physician I will not discuss the health pros and cons, but for sport activities, those who didn’t have a plan B (who did?) get lost, some, forever…
Nope, I didn’t either had a plan B. But established it quickly. Benchrest workshops turned online, our Team meetings also. All became virtual. Some, very few had some sort of range in their properties, but for the majority we just spared a lot of ammo.
Then I discover it could be a blessing for my technique and gear preparation. I had all the time to do what I needed. Time to define what I want from a rifle, from the bench gear and from my technique.
Quick bullet points, towards my rifle:
• Stock and all related hardware
• Action, bolt, bases, barrel and tuner
• Scope and rings
Stock and all related hardware
In our Team, Ricardo is a stock maker, and several other goodies for benchrest, like tuners, flags. We designed our own stock profile based on our experience and, among our rifles, just I have some other stocks than Ricardo’s.
I use two stock types, fiber and wood. The main characteristics I seek are the same:
• Low profile
o The lowest profile enhances the balance, because GC goes down, and reduces rolling tendency
o Remember that all you put above the action will raise GC, so be careful about scope weight
• Parallel riding planes
o A must for a perfect recoil and return to battery
• Rigidity
o These is achieved by a good wood combination and lamination
o Look for both longitudinal and transversal
• Vibration conduction/absorption
o Quite complex to have a consensus here…
o Having some luthier background, I always mix a good resonant wood with a muted one
I’m a believer that the best possible stock will not eliminate vibrations, but rather dissipate them from the barreled action.
• Hardware
o Plates, screws, all have to have a perfect fit
Use them to custom your stock
o Bedding is to be immaculate
Being so, it doesn’t matter much how much you torque as long as you don’t go lower than 5Nm
From my experience, and it strike me at first, with a perfectly tuned rifle, it doesn’t matter changing stocks. The groups will be the same, period. That observation, obliged me to tune perfectly my barreled actions, and showed me that testing at Lapua, if I knew what to look for, is reliable. In fact, since 2017, I only shot ammo coming from test centers.
A bit of flavor here… I did 1496 out of 1500 in 2018, with RWS R50 from their test center. So, I did 146 tens and 4 nines. Tell me it’s bad. However, the 1st time I went to Lapua testing with the same rifle, I picked that ammo to compare. Man… it did 17,5mm groups, I couldn’t believe. That ammo, at RWS test center did 12,1mm groups… How was that possible? Didn’t took much time to find the answer, but looked at the positive aspects it brought to me: “much better to know where to aim, than be lost in the wind with a killer ammo”.
I used 2020 to practice, at home, all the routine at the bench until the very moment of shooting. Crazy it might look, but fundamental. With such a practice everything becomes automatic, fluent, equal all the time. Developed photographic memory. Giving you an example. Once all gear is on the bench, but the rifle, I have my level perpendicular to the rifle’s line. Only once the rifle is leveled, I put the level parallel to the rifle’s line. So, if I miss leveling the rifle, a quick look to the table will show what’s missing. And for other items too. Don’t take any changes.
Still wonder what’s the 1st Evil?
And want to know about these two points: Action, bolt, bases, barrel and tuner; Scope and rings?
They will came next.
To be continued.
