Yes. Even if you check again in 2 weeks.

Some don't realize that loaded to similar power factors heavy bullets shoot softer. The heavier bullets produce recoil more like a push than a slap. Some loadings reveal this character
more than others. I typically shoot blaster grade 9mm 115 grain loads. Yesterday I shot 150 grain Syntech ammo, a 30% heavier bullet to similar factor. The difference is night and day
in recoil manner and tracking.
That makes sense. I picked up a box of 240gr xtp and a pound of h110 at bass pro last night just because they had it. After checking I realized h110 calls for a mag primer.

No worries I just loaded them up with 18gr of 2400 and federal 150# primer. Shot one today and noticed some unburnt powder in the chamber and case. The lee recipe called for only large pistol primers but Iím wondering if a mag primer would benefit the slower burning powder?

I had a lot easier time coming up with a load my 6.8 likes but half the fun is experimenting right? I think I got my crimps where they need to be.

Magnum primers are typically used for the slower powders. 2400 swings both ways from reading and those I have talked to through the years. Winchester sells primers labeled for standard and magnum loads. Typically, there will be unburned powder in any magnum load. My experience anyway. Some powders more than others. I’ve actually seen velocities decrease slightly with magnum primers with everything else the same.

The slower ball and coarse extruded powders benefit most from magnum primers.

Figured I would give you guys a update. Iím still learning what works for me as far as shooting a single action but Iím getting better not pulling my shots to the left.

By far my favorite load so far has been my Lee 240gr swc sized to .430 with a gas check. 9 grains of unique. Itís been nice to shoot and accurate if I do my part. I like the nice clean hole it puts in paper.

I loaded up some 240 xtp with some lil gun the other day. Definitely letís you know itís a magnum!

I have a first production year (1956) S&W 44 Magnum and I load 9.0 gr of Unique under a 240 gr flat point that I purchased from Mastercast. If I do my part I can put 6 rounds in one raggedy hole at 25 feet. That’s my go to load for that revolver.

In 44 Magnum it seems you can't go wrong with 8.0 grains to about 11.0 grains of Unique with any good 240 grain bullet.
My previously mentioned load of 10.5 grains with a240 cast SWC has shot great consistently for over 3 decades...from
one powder lot to the next.

Good shootin, trickg. Nice piece of ordnance history also with the 1956.

The Lee 240gn bullet is a good bullet (and 6 cav molds are inexpensive) but I don't use it because it won't feed in my Model 92. I considered modding the cartridge guide slots but I'm too lazy in my old age. I use Lyman 429215 and RCBS 245K molds for my three .44 guns. The Lyman 215 bullet is a good all around slug that doesn't beat you up as much as the 240's. Lee has a similar 215gn bullet but I haven't looked closely enough to see if it is the same Thompson design.
