Additional Experiments with Dynamic Non-Lead Pellets

Monday, August 18, 2008

A while back, I mentioned the good luck I had trying Dynamic SN-1 non-lead pellets in my Beeman R7 air rifle and RWS P5 pistol. A while later, I had the opportunity to chronograph the SN-1 pellets shot out of the P5 pistol, and I found that they were averaging 532 fps and varying no more than 2 fps from shot to shot! When you realize that the P5 is a spring-piston pistol, all of a sudden the light bulb comes on that this is truly astounding consistency.

Emboldened by this success, I decided to try the Dynamic SN-1 and TM-1 pellets in my recoilless RWS 54 .177 rifle. I set up the range in my yard at 39 yards (the farthest distance I can safely shoot at home). Shooting from a rest, I banged off a few shots with Crosman Premier Heavies (CPH, nominally 10.5 grain), the pellet that had produced the best accuracy with this rifle in the past. Then I shot the TM-1 pellets (9.5 grain) and the SN-1 pellets (7.95 grain).

Measuring the groups, I found the three different pellets produced very similar results. The groups from the CPH and TM-1 pellets measured 25/32”, while the group from the SN-1 pellets measured 26/32”. When I chronographed the three pellets from the same rifle a few days later, I got the following results. CPH: high 813 fps, low 798, average 804. SN-1: high 989, low982, average, 986. TM-1: high 835, low 825, average 832.

Okay, I thought, how will Dynamic pellets work in another of my favorite guns, a Steroid Sheridan Blue Streak? I shot groups at 13 and 25 yards with both JSB .20 pellets (the pellet that the Steroid ‘Dan “likes”) and Dynamic SPC-5 and got very similar accuracy results at both distances. When I got to the chronograph, I forgot to bring the JSB .20 caliber pellets (shame on me), but here are the results I got. At eight pumps, the Steroid Sheridan was sending Benjamin .20 cylindrical pellets (14.3 grain) downrange at 672 fps average (high 677, low 669). It was launching .20 Crosman premiers (14.3 grain) at 673 fps average (677 high, low 671). And it was blasting the SPC-5 pellets (12 grain) through the traps at 721 fps average (high 724, low 717).

I got excellent accuracy from the Dynamic pellets in my R7 rifle, P5 pistol, RWS 54 rifle and Sheridan Blue Streak, but not every airgun shoots them well. I got just awful accuracy shooting SN-1 pellets in my FWB 150 match rifle, and, oddly, the same thing happened with my modern vintage Sheridan Silver Streak.

From my small experiment, I conclude that some air rifles and pistols will shoot the Dynamic non-lead pellets very well, producing good velocity and higher penetration than lead pellets. While they are more expensive than conventional lead pellets, compared to match grade rimfire ammunition, the Dynamic pellets are a downright bargain and worth experimenting with.

Til next time, aim true and shoot straight.

    I would like to try shooting the Dynamic pellet in my air rifle team’s Daisy 888 and 887 rifles. I like the flat head of the PPP1 (easier for scoring) but it is shown as a pistol pellet. Can I shoot the PPP1 from a rifle? Is a heavier pellet always better? What is your recommendation? We are shooting on a 10 meter indoor range.


    1. Jock Elliott says:

      I believe you can shoot the PPP1 from your Daisy 888 or 887.

      As to whether a heavier pellet is always better, the best pellet is the one that shoots most accurately in your particular airgun. I would recommend trying some of the Daisy flat head pellets first. Unfortunately, you may have to try a variety of pellets to find the one that works best.

    Hi Jock,

    I recently bought a FX Royale from AoA, and love it. I’m blasting through so many JBS 18 grain pellets I’m starting to worry about all the lead I’m leaving in the embankment where I shoot. I use a trap about 20% of the time and need to increase that %, but I just love shooting other targets. I plan to pick up a tin of the TM 2 pellets to try them out but I’m wondering if shooting a pellet made out of a harder metal could hurt the guns barrel?
    Any thoughts?

      I have spoke several times with Cliff Tharpe, producer of the DVD on hunting the california ground squirrel. There are many locations where he is forced by law to use non-lead pellets. He frequently uses the Dynamic pellets and reports no adverse effects, and Cliff is a real fiend for accuracy.

      Bottom line, I wouldn’t worry about using the TM2 pellets in your Royale.

    Thanks much Jock! I’ll try to let you know how it goes.

    I’ve been using the pcp2 pellets in my R9 .22 with good accuracy and penetration. I plink at random ranges and targets (leaves, chunks of bark) as well as pop the occasional nuisance ground squirrel around my property and have never been too happy doing that with lead pellets. I’d say give ’em a try! John

      John, thanks for your comments.

    I agree.
