B14R .22 LR Ammo Test

[WVRJ]

I wasn’t going to say that, but since we went there, where is your support hand? It’s real easy to flex the barrel if you get on it any little bit at all.

Also, is it recoiling straight back the same each time when you are holding it? Do you have the rear in a bind pulling the crosshairs where you want them? That won’t let recoil be consistent and straight back.

Shoulder pressure consistent even if we are recoiling straight back?

Just a couple of things to think about.

I'm shooting it on a front rest with a lobe bag and I have a flat 3 inch bag rider that screws on using the holes for the front swivel studs.The rear is in a Protektor bag that sits on a block that has sharp studs sticking out the bottom of it.I use the adjustments on the front rest to line up the dot reticle on the x-dot of a regulation 22 benchrest target.I use very little shoulder into the rifle and try to let it slide back as straight as I can.I've shot a fair amount of centerfire benchrest,but the 22 is a different game in some aspects.The B-14 is very capable of one hole groups at 50 yards if it's operated right.I've got several 100 yard groups in the 3/4 inch class with it.I shot it at 300 yards this past Sunday,and that was a humbling experience.I have a B-14 HMR in 6.5 Creedmoor that I also shot Sunday at 300 yards,and it was shooting groups around an inch right along.The rimfire was shooting patterns that were minute of milk jug at the best,but I'm making progress.

Then you're good to go, stop overthinking it, it will come together.

.22s do have more dwell time though.

test a variety of ammo.

Nice shooting.

I wonder how CCI Standard Velocity would compare?

Fired today @ 50 yards.

It's kinda interesting to see the dot in the scope move and have the bullet land in the same direction as the movement.I'm going to install a 2 ounce trigger in it this weekend.Just the amount of tension it takes to get the 1.5 pound Trigger Tech I have on it now to break will upset the rifle enough to cause fliers.The 22 will bring out any problems in the shooter's form and follow through a lot more than center fire.Hopefully a lighter trigger will make me more consistent.Concentration and follow through have been problem areas for me for years,no matter if it's rifle,shotgun or bow.I want to be the guy shooting a surprise release with a bow that doesn't even blink when the shot breaks,but it seems like I don't have that level of concentration.

My target .22 has a BiX'n Andy TacSport Pro (TT is just as good, just a different feel) set at around 7 (IIRC) ounces. My old Benchrest rifle has a two ounce Jewel.

And contrary to popular belief, the break of the trigger doesn't need to be a "surprise" to shoot great groups.

Back when I shot in registered Benchrest matches I knew when I was concentrating well when I got done with a group and realized I had not heard any of the shots from the benches next to me.

Man ... I really want one of those rifles. I've been holding myself back from getting one though. I really don't want to go down that rimfire rabbit hole again.

I didn't see where you tried CCI standard velocity. It wasn't the best in any rifle I've ever owned but far from the worst and good for golf balls and peppermint at 100.

The best way I've found to do this sort of work is indoors with no wind.

Several more I need to try including CCI Green Tag and Standard Velocity.

I agree, if the shot is a surprise you don't need a fast lock time and in my opinion don't know what you are doing.

Nice shooting now enter that thing in the Dayattherange Z Challenge WOW way to go looks like you got a shooter. NICE.

I totally agree with this, especially with rimfire where the bullets are ultra sensitive to wind conditions, which can change from one second to the next. I want my shot going off when I need it to.

Spent some time last Friday back at the range with the B14R and a variety of ammo, purpose to get some velocities from the ammo I shot in the original test. Took me a while to figure out how to situate myself relative to the Labradar so that it would reliably pick up the rimfire, but once done, it missed very few. I'll post a pic of the data table soon. One of the strengths of the Labradar quickly became apparent.

Have you tried to find ballistic coefficients for various .22 LR ammo to plug into a calculator? Well, the Labradar reads velocity at multiple user-set distances. Since I was shooting at a 50 yard target, I read velocities at the muzzle and at 45 yards. With the two data points and the JBM Ballistics Ballistic Coefficient calculator I was able to computer BCs for several different types of ammo. I did the calculations after the range outing.

In addition to shooting for velocity, I also moved out to 100 yards to get a sense of drop. The RWS R50 ammo dropped an observed 1.8 mils (about 6.5 inches) at 100. When I got home, I had the observed muzzle velocity (1125 fps) and a calculated BC (0.168). With those, I ran the data through the JBM Ballistics Trajectory Calculator, which projected a -6.5 inch or -1.8 mil drop at 100 from a 50 yard zero. Happy for the confirmation.
