I want to reduce the weight of the cast bullets for Dad's 45/60 rifle
As ( he will not admit it ) the steel butt plate on his rifle is't easy on his 79 year old shoulder
Also cutting the stock is a NO NO as is about anything else in his mind
I tried sub 300 gr bullets , but the groups opened way up ... IMO maybe bearing length was the problem
So I tried putting HP's in a 300 gr GC bullet
I went and made 250 gr GC bullets
I had to seat them deep because of the bullet design , but the groups I shot were good
So I am planning on making him a HP GC mold .... I was thinking a GC to reinforce the base so I make the HP any depth I wanted
I was thinking of a 300 gr length to stick to what normally loaded
But making the HP stem so I can change the weight
My questions are
Also how close to the base of the bullet could I go and not be afraid of the base blowing through ?
How thin could I make the sides of the HP and expect the bullet to hold up ? .... last resort is to go real thin
Thanks
John
