Default 1:20 .45 cal Hoyt barrel

This was my virgin run with my new relined barrel from Bob Hoyt. Its a .45 cal Hawken barrel with a 1:20 twist. During this range session I was also testing some bullets EdMehlig sent me (I bullet design). THANKS ED.[
I installed a globe front sight and planned on putting a vernier tang sight on it but my sight would not go down far enough. I ordered a higher globe sight for use with the vernier but in the interim I installed my Lyman 57 SML sight.
I shot one of my 350 gr FP conicals at the target and then made a sight adjustment (impact was the lowest one on the target) I then shot 70 gr each of FFFg, Pyro P, and Truple 7 at 50 yards. The T7 showing the most promise.
I pulled the target and took it out to 100 yards and fired 3 shots with the I bullet and the 70 gr of T7. Group was about 3". OK but not real good. Then using the same 70 gr of T7 and my 350 gr FP cast bullet I put the 3 just above the bull. I think This is going to be my load. At this point I don't seen any reason the invest in an I bullet mold the way mine shoot.

Always a good idea to stick with a winner. My 1:30 twist .45 caliber Green Mountain barrel Renegade loves Ed's 350 grain soft lead flat base in either the flat nose or hollow point persuasion. You just need to be mindful of trajectory when hunting with them. Check out the old 150 yard target with a note about impact at 100 yards.

(NOTE: The rifle is one of the Sinful Sisters and wears a 4X scope. And we all know "It's a Sin to scope a sidelock.")

Semi I was conversing with Ed today because I don't think its fair to make a comparison with just one group. I will be heading out again soon and do some more side by side shooting. Both bullets are very similar in weight and profile. Ed is going to send me his Accurate 45-465M mold to cast some bullets and try.
I've been considering the 45-480M mold from Accurate.

Those 465's are really nice bullets. Are you going to cast with pure lead, an alloy, or some of each?

I'd forgotten how well those 465's shot from the GM Renegade until I went back and looked through my old target file. I suspect they will do even better from that 1:20 twist.

Here's an interesting one of the old targets with the gun sighted in to be 1.5" high at 100 yards, and two shots each at 50, 75, 100, 125 and 150 yards using the same point of aim for all shots.

Probably cast them with a 1:40 alloy. If they shoot good and he doesn't want to sell me it I may just order a 45-480M mold from Accurate. If I do I'll order it with a .452" +.002 -.000 tolerance. Then I can always size it down a bit.
I just got done casting some .457" 350 gr bullets (the ones I shot in the first target) and sized them down to .451" in 2 stages. I sized to .454", lubed them then to .451".
That much sizing though takes a lot off the lube grooves.

Wow looking at your target that bullet drops 9" from 100 to 150 yards!
