Re: 22LR Bullet Shapers/Sizers
After reshaping some 22LR with the Waltz die using the "EPS" punch shape, I went to the range this afternoon to see whether there would be an improvement in group size. The bottom line is that reshaping made an improvement for some ammo types and not for one I tested.
My rifle is a Remington 40X barreled action in an AICS, with an original 22" long barrel and a total of about 400 - 500 rounds down the tube. I used a 12x scope and my target was at 100 yards.
For this 22LR only, I clean the barrel after every trip to the range. Before firing for record, I shot 10 rounds of each type of ammo to acclimate the barrel to that particular ammo type.
I tried the following 22LR ammo:
* Lapua Speed Ace (orange box)
* Wolf Match Target (MT)
* Federal GMM (711B)
* Aguila SE High Velocity (copper plated 40-gr round nose bullet, circa 1,250 fps)
* Eley Match EPS (used only for group size comparison, not reshaped)
Reshaping improved the group size of all of these ammo types except the Federal GMM. The group sizes were estimated by eye, not measured with a caliper. My paper targets have 1/4" horizontal and vertical lines to assist in making eyeball measurements.
The factory Eley EPS had the smallest 10-shot group, about 1/2 inch at 100 yards, one ragged hole, and was clearly the best out of my 40X.
The Wolf MT 10-shot group was 1" to 1.5"; but after reshaping, the group size decreased by about one-third or 3/4" to 1".
The Aguila SE was third and only slightly worse than the Wolf MT after reshaping. These bullets are copper plated and there was no problem reshaping them. A small dab of wax remained on the "nub" after reshaping and you should clean it off before use.
The Lapua Speed Ace was fourth, with a 10-shot group of about 1.25" to 1.5" after reshaping, better than the factory round.
The Federal GMM Target shot poorly, about 1.5" to 2". Reshaping did little to improve the group size. I suspect there were other factors that affected the accuracy of this round, such as variations in primer or powder load since a few rounds failed to fire.
My conclusion is that Eley EPS is the best ammo for my 40X if I were punching paper at 100 yards in a match. For practice or simply to save money, the reshaped Wolf MT is 1 MOA or better at the same distance. However, if I want to shoot at 200 or 300 yards, the Aguila SE High Velocity is almost as good as the reshaped Wolf MT at 100 yards and needs less elevation at the longer distances. I fired both subsonic and high velocity 22LR to 200 and 300 yards today and the subsonic required several more MOA - I didn't make notes or exact measurements, but the difference was surprising (a few mils at 300 yards). The Aguila SE performed well at 300 yards and would be my choice for hunting or long-range match use at this point over the reshaped Wolf MT.
