I just finish to build a hybrid between the 2300 s and 2300t. It s a crosman 10.1" barrel and i whant to find the best pellet for it.

This is the way i think to go.

1- pass a dry patch to remove exess lube leave by the previous pellets.

2- shoot 20 pellets to season the barrel

3- shoot 6 targets with 5 pellets, take mesurment and make a avreage.

I got 8 kind of pellet to test, from the cheaper to expensive one.

You think that way will do the job for a accurate result ?

First I would clean the barrel with some patches with lube and then pull several dry patches through. Then season the barrel as you said. Then start the testing.

By now you should know when velocity starts to drop off with a powerlet/bulb. Take all your testing shots after maybe the 5th shot on a fresh bulb and stop a couple before when the power starts dropping. This might mean you only get to test one or two pellet types from a bulb.

A pistol with iron sights is not easy to benchrest test unless your eyes are 100% and you can shoot without any movement. When testing pellets I put more trust in a mechanical rest so I clamp the trigger guard in a Black & Decker Workmate. I put the workmate on a stable surface, not on the lawn like in the pic. The Workmate model in the pic below is more sturdy than the quick folding cheapo model that wobbles. A CO2 pistol doesn't move much and can be cocked carefully without moving the frame. I once tested a Steyr LP10 CO2 in my Workmate and it produced small one hole groups that looked like a single pellet hole. My TAU-7 gives me around .20" to .25" with good pellets.

Don't limit yourself to 10m. Take your pistol out to 20 and 30 yards to compare pellets.

For the co2 the first 5 shoots of every test is shoot on a off test target.

For testing i put a pistol scope on the gun . At Every session of testing i shoot on the chrony to make sure i get enough co2 to stay over 485 fps ( the pistol shoot 495 fps with 7.4 gr).

For distance for now i only have acces to my basement, 20 yars and over should be done next spring.

Thank for the advise

When switching pellets, I've usually found no more than 2 to 4 shots are needed, to re-condition the bore to that next pellet.
I usually just fine off 3 or 4 and start grouping. Works for me. I use a sand bag and rest my hand against it, with the air-tank supported by the bag.
20 just seems a waste of CO2 to me.
Clicking on the picture will enlarge it. The gun sitting on the bag is the same when shooting., with my hands (both) griping the gun properly. This method
has allowed me to shoot 1/2" and smaller groups at 20 yards, with my sub 500fps handgun (red dot sight).

Here's the very old TAU-7 Review I put together. Accuracy during my tests was .230"ctc over 10 groups at 10m. I tested this pistol out to 40 yards and got 0.95" average at 40 with the preferred pellet.

I like that PCP pistol that Daryl just showed us! Very nice!

I imagine those searching for better accuracy beyond 10m from a rested position would benefit. I'm not convinced for 10m standing it would make much difference. I don't clean, lube or anything. I just open the tin and shoot. No testing either, just picked H&N sports from the start and haven't looked back. Some friends at the club shoot match and final match but I don't see any difference in scoring.

My real concern is to cut or minimise the flyer, may be a lw barrel do the job to.

Flyiers are usually caused by shooter error, in my opinion, if using good pellets. Chinese or other inexpensive pellets with particles of lead inside the skirt
will cause fliers, of course. Many serious shooters clean their pellets. I have not done this - yet. Guess I'm not serious. I have never had a flyer with JSB
Cometa match pellets in my .177 HW97, nor in the .22 PP700 S-A using H&H 19.09 Barracuda Hunters nor H&H Match RN's at 21.3gr.

Just finish the test with the crosman barrel.

Really surprise the crosman wadcutter 7.4 grains was the best with a .618" at 10 m follow by excite econ II at .625". The worst is h&n final match light with 0.885".

Gamo match
Winchester wc
Crosman pointed
All around 0.750"

I keep my rws hobby and rws mert... To test with the lw barrel

You could probably get down to 1/2" or less. Maybe try some H&N Finale Match Rifle, H&N Field Target Trophy, JSB Exact 8.44gr, JSB Exact Express, and JSB Match Middle. I've never tested a Crosman 1740 but with good pellets I got 3/8" and smaller with a Cr2240 and a Cr Mk1.

Is it more a 2300 serie i put the valve with the reducer, the other one i worked on it will be a 1740 i stick with the regular valve.

With the reduced valve i see liigther is the pellet better is the accuracy, the h&n 7.87 gr is far away the worst i test and it s a good quality pellet cheap 7.4 and 7.5 do lot more better.

Sometimes a heavy pellet still shoots great from a low velocity air pistol. The Mk1 I tested was only shooting 8.44gr JSB Exact at around 400fps but they grouped .32" at 10m (many groups). My old TAU-7 shot accurately with the 8.44gr Exact at 450fps. My current TAU-7 does well with the 8.64gr H&H FTT at 450fps but it also likes the H&N Finale Match Rifle. It shoots both into 1/4" groups at 10m. My P17 pistols like the 8.44gr JSB Exact and also the 8.64gr H&N FTT and they are only moving at around 385-400fps.

We can't determine the best pellet by eliminating certain options because of weight. Pellet head & skirt size consistency is very important. Sometimes a longer or shorter pellet stabilizes better. Sometimes a wider or narrower skirt or head do better. Sometimes thinner or thicker skirt walls seem to shoot best. Sometimes a lighter pellet option is made by thinning out the skirt and deepening the skirt hole (JSB Exact Express vs RS). This changes pellet balance and may or may not benefit accuracy in the specific pistol.

With pellets that your 2300/1740 likes, it should group 1/2" and very likely less. If not, then check the transfer port and the crown for burrs.
